Working With Us

## Working With Adrian Electric

How much does electrical work cost, like a panel upgrade?

It depends on the scope, the condition of your existing wiring and what the permit requires. Service call and hourly rates are on our [Rate Sheet](https://jladrianelectric.com/rate-sheet?hsLang=en), and typical ranges for projects like panel upgrades are in our [Cost Guide](https://jladrianelectric.com/cost-guide?hsLang=en). Your actual price is the one in your written proposal.

Do you give free estimates?

Yes, by phone or from photos you send. That's a rough estimate, not a final price. For an exact proposal we schedule an on-site consultation. The fee is on our Rate Sheet and credited in full toward your project when you accept the proposal.

Are you licensed and insured?

Yes. J.L. Adrian Electric LLC holds Texas electrical contractor license TECL #39231 and is led by Texas Master Electrician Jacob Adrian, TMEL #630657. Here's [how to verify any electrician's license in Texas](https://jladrianelectric.com/adrian-electric/verify-a-licensed-electrician-in-texas-adrian-electric?hsLang=en).

What's the difference between a licensed electrician and a handyman?

A licensed electrician has passed Texas-required training, testing and licensing, and carries the insurance and code knowledge to do electrical work legally and safely. A handyman typically isn't licensed for electrical work, and using one for anything beyond very minor tasks can cause failed inspections, permit problems and real safety risks.

What areas around El Campo do you serve?

All of Wharton County, plus Fort Bend, Jackson, Victoria, Matagorda, Lavaca and Colorado counties. Not sure if you're in range? Just call.

Do you offer emergency or after-hours service?

During business hours, Monday–Friday 8–5, call us at [(979) 559-3684](tel:9795593684). After hours, send a request through our [contact form](https://jladrianelectric.com/contact-us?hsLang=en) and choose "Emergency / same day." We take emergency calls when someone is available, but we can't guarantee an after-hours response time. Work outside normal hours is billed at the after-hours rates on our Rate Sheet.

**If you see smoke, fire or a downed power line, call 911 or your utility first.**

Do I need a permit for electrical work, like a ceiling fan?

It depends on the work and your city or county. Swapping a fixture or fan on existing wiring often doesn't need one. New wiring, new circuits, panel work and service changes usually do. Where the local authority requires a licensed electrical contractor to pull the permit, we pull it, and the permit fee is passed through to you.

How long does a whole-home rewire take?

It depends on the size of the home, attic and wall access, and whether you're living there during the work. It can be a few days for a smaller home or a couple of weeks for a larger or more complex one. We'll walk you through the expected schedule after an on-site consultation.

Is your work warrantied?

Yes. Our workmanship warranty and how to make a claim are spelled out in our [Terms of Service](https://jladrianelectric.com/terms-of-service-v7?hsLang=en). On equipment we supply, like generators and EV chargers, we also register the manufacturer warranty for you.

Breakers & Panels

## Breakers, Fuses & Electrical Panels

What's the difference between a fuse and a circuit breaker?

Both cut power when a circuit is overloaded or shorted. A fuse has a metal strip that melts, so a blown fuse has to be replaced. A breaker trips, snapping to "off" or a middle position, and can be reset. Breakers are safer and more convenient, which is why modern homes use them.

Why does my circuit breaker keep tripping?

The usual causes are an overloaded circuit (too many devices on it), a short circuit, a ground fault, or an appliance that draws more than the circuit can handle and needs its own dedicated circuit. Spreading heavy loads across circuits helps with overloads, but a breaker that trips again and again needs to be traced by an electrician. Read more: [the real causes of a tripping breaker](https://jladrianelectric.com/adrian-electric/circuit-breaker-keeps-tripping-real-causes-el-campo-tx?hsLang=en).

Can I reset my own breaker? What if it won't reset?

Yes. Unplug a few things on that circuit, push the breaker fully to OFF, then back to ON. Resetting once or twice is fine. If it trips right away, won't stay on, or keeps tripping, leave it off and call an electrician. That usually means a real fault.

What should every homeowner know about their breaker panel?

Know where it is, keep the area in front of it clear, and make sure the circuits are labeled so you can shut one off quickly. Know how to reset a tripped breaker. Have it looked at if you notice heat, buzzing, scorch marks, breakers that won't stay on, or a brand known for problems.

What's an AFCI breaker, and do I need both AFCI and GFCI?

An AFCI (arc-fault) breaker detects dangerous arcing that can start fires inside walls. A GFCI (ground-fault) device detects current leaking to ground, which causes shocks. A standard breaker only protects against overloads and short circuits. AFCI and GFCI protect against different hazards, and current code requires both in many parts of the home. Dual-function breakers combine the two in one device.

Should I replace my fuse box with a breaker panel?

Usually, yes. Fuse boxes tend to be small, 60 to 100 amps, and can't add modern AFCI and GFCI protection. Some insurers also look at them closely. Upgrading makes the most sense when you're adding central AC, an EV charger or other big loads. A load calculation tells you what size you actually need.

When should I upgrade my electrical panel?

Common reasons are adding central AC, an EV charger, a hot tub, a shop or solar, running out of breaker spaces, having a 60 to 100 amp service in a growing home, or having a problem-prone panel brand. Read more: [100 vs 200 amp panel upgrades](https://jladrianelectric.com/adrian-electric/100-vs-200-amp-electrical-panel-upgrade-el-campo-tx?hsLang=en).

How many amps does my house need?

Most newer homes have 150 to 200 amp service. If you have or plan to add central AC, an EV charger, an electric range or other major loads, 200 amps is usually the safer choice. The real answer comes from a load calculation of your home, which we include in any service upgrade proposal.

What is a subpanel, and when do I need one?

A subpanel is a second breaker panel fed from your main panel. It adds circuits in a specific area without running every circuit back to the main panel. Subpanels are common for garages, shops, additions and detached buildings.

What's an overcrowded or double-tapped panel?

It's a panel with too many wires crammed in, or two wires under a breaker made for one, which is called a double tap. Loose or overheated connections and code violations are the result. It's usually a sign the panel has outgrown the home and needs more spaces or a subpanel.

Is my panel a problem brand, like Federal Pacific or Zinsco?

Federal Pacific panels usually say "Federal Pacific," "FPE" or "Stab-Lok," often on breakers with red stripes. Zinsco panels may show a Zinsco or Sylvania/GTE-Sylvania label and brightly colored breakers. Both brands have widely reported breaker problems, including breakers that may not trip during an overload. If you have either one, have it evaluated by a licensed electrician.

Is it normal for my breaker panel to hum?

A very faint hum can be normal. A loud buzz, crackling, or a hum that keeps getting louder isn't. It can point to a loose connection, an overloaded breaker or a failing part, and should be checked promptly.

What is a smart panel or smart breaker, and is it worth it?

Smart panels and breakers add real-time energy monitoring and remote control of individual circuits from an app, and sometimes automatic load control. You don't need one, but they're popular with homeowners who want detailed usage data, or who are adding solar, batteries or an EV charger.

Outlets & GFCI

## Outlets, GFCIs & Plugs

What is a GFCI outlet, and where do I need one?

A GFCI (ground-fault circuit interrupter) shuts off power in a fraction of a second if it detects current leaking somewhere it shouldn't, like through water or a person, which prevents shocks. Code requires GFCI protection in higher-risk areas such as bathrooms, kitchens, laundry areas, garages, outdoors, crawl spaces and near sinks.

An outlet stopped working but the breaker isn't tripped. How do I reset a GFCI?

Look for a GFCI outlet with TEST and RESET buttons and press RESET firmly. One GFCI can protect several outlets downstream, sometimes in another room, garage or outside, so check nearby bathrooms and the garage too. If it won't reset or trips again right away, there's likely a fault in the outlet, the wiring or whatever's plugged in, and it needs an electrician.

What's the difference between a GFCI outlet and a GFCI breaker?

Both detect ground faults and cut power. A GFCI outlet protects itself and anything wired downstream of it. A GFCI breaker protects the whole circuit from the panel out. Which one makes sense depends on the circuit and where it's easiest to reset.

Can I put a GFCI outlet anywhere, or only where it's required?

You can add GFCI protection anywhere for extra safety. Code only requires it in specific areas, but adding it elsewhere is never wrong. One exception is equipment like a freezer or sump pump, where a nuisance trip could go unnoticed. Talk to us about where those should go.

Why does my outlet spark when I plug something in?

A tiny, quick spark can be normal as the plug's contacts meet, especially with something that's switched on. Bright, loud or repeated sparks, scorch marks, or an outlet that's quit working point to loose wiring, worn contacts or water damage. Stop using it and have it checked.

Why is my outlet hot to the touch?

That's a warning sign of an overloaded outlet or a loose, overheating connection. Unplug everything from it, stop using it, and call an electrician. If you smell burning or see smoke, shut off the breaker if it's safe to, and call 911 if there's fire.

Why do plugs fall out of my outlets?

The metal contacts inside have worn out and lost their grip. A loose fit can also cause heat at the plug, so the outlet should be replaced.

What's the difference between two-prong and three-prong outlets?

The third, round prong is the ground. It gives stray current a safe path away from you and protects your electronics. Two-prong outlets are ungrounded. Don't just swap in a three-prong outlet. The proper fixes are running a ground or adding GFCI protection with the correct labeling, which an electrician can do.

Why don't my outlets have enough power for my devices?

Older homes often have just a few circuits shared across many rooms. Space heaters, microwaves, gaming PCs and window units can overload them. The fix is usually a new dedicated circuit for the heavy load. Just putting in a bigger breaker isn't safe unless the wire is sized for it.

How do I know if my home has too few outlets?

If you rely on extension cords or power strips for everyday use, or run cords across rooms, you need more outlets. Adding them is usually a straightforward job and safer than living on cords.

Are extension cords, cube taps and outlet extenders safe?

Only for light, temporary use. They aren't meant to replace permanent outlets. Running high-draw devices through them, or using them long-term, is a common cause of overheated plugs and house fires.

What is a tamper-resistant outlet, and do I need them?

They have built-in shutters that only open when both prongs go in at once, so a child can't push a key or paper clip inside. They're required in new homes and are a smart upgrade if you have kids.

Should I install USB outlets?

They're not required, but they're handy in kitchens, bedrooms and offices for charging phones and tablets without adapters. They're a common add-on when we're already working on outlets.

Why are some of my outlets upside down?

Some electricians install them with the ground pin on top, and you see it often in commercial buildings. Either direction is allowed. Sometimes it's also used to mark the outlet a wall switch controls. It doesn't need fixing unless you prefer it flipped.

Lighting

## Lighting, Switches & Dimmers

Why do my lights flicker or dim?

A loose bulb or an incompatible dimmer is the harmless explanation. Flickering in several rooms, or lights dimming when the AC or another big appliance kicks on, can point to a loose connection, an overloaded circuit or a problem with your service. Those need an electrician. Read more: [what's harmless and what isn't](https://jladrianelectric.com/adrian-electric/why-do-my-lights-flicker-or-dim-el-campo-tx-electrician?hsLang=en).

Why do my lights flicker when it's windy?

Usually a loose connection at the overhead service line, or tree branches rubbing the lines. Call your power company first. If they find the problem is on your side of the meter, such as the weatherhead or meter base, that's work we can do.

Why do my lights flicker during storms?

Brief flickers during storms are usually voltage dips or surges on the utility lines as equipment switches or lightning hits nearby. If it happens in clear weather too, it's more likely a problem in your home's wiring. See [surges and storms](https://jladrianelectric.com/frequently-asked-questions#surges) below for ways to reduce surge risk.

Why do my light bulbs burn out so often?

Common causes are bulbs with too high a wattage for the fixture (overlamping), vibration from a ceiling fan or garage door, cheap bulbs, a loose socket connection, or voltage problems. Switching to quality LEDs fixes most cases. If bulbs keep failing in several fixtures, have the voltage checked.

What is overlamping, and why is it dangerous?

Overlamping means using a bulb with a higher wattage than the fixture is rated for. The extra heat can melt the socket and wire insulation and create a fire risk. Match the bulb to the maximum wattage printed in the fixture, or use LEDs, which run much cooler. Read more: [overlamping and fire hazards](https://jladrianelectric.com/adrian-electric/overlamping-light-fixture-fire-hazard?hsLang=en).

Why do my LED lights buzz or flicker on a dimmer? Can I dim any light?

You can only dim bulbs labeled "dimmable." Even then, older dimmers made for incandescent bulbs often make LEDs buzz, flicker or stay faintly on, because LEDs draw far less power. For smooth dimming, you need both a dimmable LED and an LED-rated dimmer switch.

How do I upgrade to LED lighting without problems?

Use dimmable LEDs with LED-rated dimmers wherever you dim. For fluorescent fixtures, use LED tubes made for your setup, or have the ballast bypassed or the fixture replaced. Pick the color temperature you want before buying in bulk.

What's the difference between color temperature and brightness?

Color temperature, in Kelvin, is the color of the light. 2700K is warm and yellowish like an old incandescent bulb, and 5000K is cool, bluish-white like daylight. Brightness is measured separately in lumens, so two bulbs can be the same color and very different in brightness.

Do recessed lights need to be IC-rated?

If insulation will touch the fixture, yes. "IC-rated" means it's safe for direct contact with insulation. A non-IC can covered by attic insulation can trap heat and become a fire hazard.

How do I safely replace a light fixture?

Turn off the breaker, not just the wall switch, and confirm the power is off with a voltage tester before touching any wires. Make sure the box can support the new fixture's weight, especially a ceiling fan. If the wiring is old, brittle, aluminum or confusing, stop and call an electrician.

Why does my light switch flicker, buzz or stop working?

Common causes are a worn-out switch, a loose wire connection or an incompatible LED and dimmer pair. A switch that's warm, buzzes loudly or crackles should be replaced. With the power off, a multimeter continuity test confirms a bad switch.

Why do smart switches need a professional install?

Many smart switches and dimmers need a neutral wire in the switch box, which older homes often don't have. They also need the right load rating and multi-way wiring setup, and a good Wi-Fi signal. An electrician can confirm your boxes are compatible or run what's needed.

Wiring & Older Homes

## Wiring, Inspections & Older Homes

Is aluminum wiring safe in older homes?

Aluminum branch-circuit wiring was used in many homes in the 1960s and 70s. It expands and contracts more than copper, so connections can loosen, overheat and become a fire risk over time. It can be made much safer by repairing the connections with connectors approved for aluminum, or by rewiring. Read more: [aluminum and knob-and-tube wiring](https://jladrianelectric.com/adrian-electric/aluminum-knob-and-tube-wiring?hsLang=en).

What is knob-and-tube wiring, and when should it be replaced?

It's very early wiring, common from the 1900s through the 1940s, run on porcelain knobs and tubes. It has no ground, its insulation gets brittle with age, and it wasn't designed to be buried in insulation. Plan to replace it during any major renovation, or sooner if it's damaged or your insurer won't cover the home.

Copper or aluminum wire for new circuits?

Copper is the standard for household branch circuits. Aluminum is still commonly and safely used for larger feeders and service-entrance conductors when it's sized correctly and terminated with the right connectors and torque.

What are the signs of outdated or faulty wiring?

Watch for breakers that trip often, flickering lights, warm or discolored outlets and switches, buzzing, burning smells, two-prong outlets, cloth-covered wiring, aluminum branch wiring, no GFCI or AFCI protection, and an undersized or problem-brand panel. Any one of these is worth having checked.

How often should I have my home's wiring inspected?

There's no single required schedule. Good times to have it checked are when you buy a home, when the home is 40 or more years old and hasn't been looked at, before a remodel or addition, after a flood, fire or lightning strike, when your insurer asks, or any time you notice warning signs. Our [electrical safety inspection](https://jladrianelectric.com/residential-electrician?hsLang=en) is a licensed electrician's evaluation of your system. It isn't a real estate inspection.

Does my old wiring have to be brought up to current code?

Generally, no. Wiring that met code when it was installed is usually allowed to stay, which is often called being grandfathered. New work, renovations and additions typically have to meet current code, and grandfathering never covers wiring that has become unsafe.

How can I find out if my home meets current electrical code?

Schedule an electrical safety inspection with a licensed electrician. We'll walk through your panel, wiring and protection, explain what we find, and tell you what's urgent and what can wait. Any repairs are quoted in writing.

What's the problem with uncovered junction boxes?

An open junction box leaves live connections exposed to touch, dust and pests. Every box needs a proper cover, and it has to stay accessible, not buried behind drywall.

Why does part of my house lose power, or work only sometimes?

Check the panel for a tripped breaker and look for a tripped GFCI first. If those are fine, the usual cause is a loose or corroded connection, often at a "backstabbed" outlet where the wire is pushed into the back instead of wrapped on a screw. These get worse over time and need an electrician.

**If half the house is out, or lights suddenly get much brighter or dimmer,** you may have lost a utility leg or neutral, which can damage electronics. Unplug sensitive equipment and call your power company right away.

Surges & Storms

## Surges, Storms & Generators

What causes power surges?

Lightning, utility switching and power restoration after outages are the big outside causes. Inside the home, large motors cycling on and off, like AC compressors and well pumps, create smaller surges all day long that can wear down electronics over time.

What is a whole-house surge protector, and do I need one?

It's a device installed at your main panel that limits voltage spikes coming into the home. We recommend whole-home surge protection for most homes, especially with expensive electronics, smart appliances, HVAC equipment or an EV charger. Pairing it with quality plug-in surge strips for sensitive electronics adds another layer.

When a home's electrical service is replaced or upgraded, current code requires a surge protective device as part of the job. Surge protection reduces risk, but no device prevents all damage from surges, lightning or utility problems.

What should I do after a lightning strike or house fire before turning the power back on?

Don't restore power yourself. Have a licensed electrician inspect the panel, wiring and affected circuits first. Heat and surges can damage wiring and parts in ways you can't see, and re-energizing damaged wiring can start a second fire.

My home flooded. Is it safe to turn the power back on?

Not until it's been checked. If water reached outlets, the panel, wiring or appliances, leave the power off and have a licensed electrician inspect before anything is re-energized. Flooded breakers, outlets and some wiring usually need to be replaced, not dried out.

How do I safely connect a portable generator to my house?

The safe way is a generator inlet box outside and a transfer switch or a code-approved interlock on your panel, installed by a licensed electrician. Then you plug in one cord and run the circuits you choose.

**Never backfeed a generator through a dryer or other outlet with a double-ended cord.** It can electrocute utility workers and your own family, and it can start a fire. Always run portable generators outdoors, away from windows and doors.

Should I get a standby generator?

If outages here have meant spoiled food, a hot house, a dead well pump, or someone at home who needs power, a standby generator starts on its own within seconds of an outage, with no cords or refueling a gas can. We're an authorized Generac, Briggs & Stratton and Cummins dealer. See our [standby generator installation](https://jladrianelectric.com/standby-generator-installation?hsLang=en) page and [hurricane season guide](https://jladrianelectric.com/adrian-electric/whole-home-generator-hurricane-season-guide?hsLang=en).

Safety & DIY

## Electrical Safety & Do-It-Yourself Work

Is it safe to do my own electrical work?

Simple tasks are fine for most homeowners, like changing a bulb, swapping a cover plate, resetting a breaker or GFCI, or replacing a plug-in device. Work inside boxes and panels, or new circuits, carries real risks: shock, electrocution, fire, failed inspections, and trouble with insurance claims or selling the home.

When should I call an electrician instead of doing it myself?

Call any time the job means opening the panel, adding or changing circuits, working with aluminum or old cloth wiring, or connecting a generator. Call right away if you see signs of a problem: burning smells, heat, scorch marks, buzzing, or breakers that won't stay on. Start simple troubleshooting at the panel, then outlets and fixtures, and stop there.

Can Texas homeowners do their own wiring?

Texas law generally allows homeowners to do electrical work on the home they own and live in. Your city or county may still require permits and inspections, or limit what you can do, and the work has to meet the National Electrical Code and local amendments. Check with your local building department before you start. Insurers and future buyers may also ask who did the work.

How can I prevent electrical fires at home?

Don't overload outlets or rely on extension cords long-term. Replace damaged cords and plugs right away. Use the right bulbs for your fixtures. Make sure you have AFCI and GFCI protection where it's required, and keep smoke alarms working. Have warning signs like heat, buzzing or flickering checked instead of ignored.

What should I do if I smell burning near an outlet, switch or panel?

A burning or hot-plastic smell usually means overheating wires, melting insulation or arcing. Unplug what you can, turn off that breaker if it's safe to reach, don't use the outlet or switch again, and call an electrician.

**If you see smoke or flames, get everyone out and call 911.**

Energy, EV & Solar

## Energy Use, EV Chargers & Solar

What uses the most electricity in my home?

In a Texas home, heating and cooling are almost always the biggest share. After that it's usually the water heater (if it's electric), refrigerators and freezers, the washer and dryer, pool pumps, and lighting.

What's the best way to save energy with my electrical system?

Switch to LED lighting, use a smart thermostat, replace old inefficient appliances when it's time, seal air leaks, and add timers or smart controls for pool pumps and outdoor lighting.

Why is my electric bill so high?

The usual causes are an aging AC system, poor insulation, old appliances, devices left on standby, or a pool pump running more than it needs to. A failing appliance or a wiring problem can also raise usage.

Check your rate too. In areas where you choose your provider, plans often jump to a higher rate after the contract ends. You can compare plans on the state's official site, [Power to Choose](https://www.powertochoose.org/). Electric co-op members don't choose a provider, so this doesn't apply to them.

How do I install an EV charger safely? Why does my charger breaker trip?

A Level 2 charger needs a dedicated 240-volt circuit sized to the charger's rating. Because it's a continuous load, the circuit is sized above what the charger draws. For example, a 40-amp charger goes on a 50-amp circuit. A charger breaker that trips usually means the circuit is too small, is shared with other loads, or has a bad connection. We include a load calculation with every EV charger proposal so your panel isn't overloaded.

Can I add solar panels to my home's electrical system?

Usually, yes. It may require a panel or service upgrade, the right inverter and disconnects, permits, and your utility's approval to interconnect. We handle the electrical side, including the panel work and the tie-in. We don't promise any tax credit, rebate or savings. Check eligibility with your tax professional and your utility.

Appliances & Troubleshooting

## Appliances, Motors & Electrical Basics

Why did my appliance suddenly stop working?

Check the simple things first: a tripped GFCI or breaker, a loose plug, or a dead outlet. If the outlet works with something else plugged in, the problem is likely inside the appliance, such as a blown internal fuse, a failed part, or surge damage.

Why does my appliance keep blowing its fuse?

A blown fuse inside an appliance usually means an overload or an internal short. Replace it only with the exact same rating. If the new fuse blows too, the appliance has a fault that needs repair. Never use a higher-rated fuse.

What is a thermal fuse, and why does it blow?

It's a one-time safety device that cuts power if an appliance overheats. It's common in dryers, coffee makers and space heaters. A blown thermal fuse usually points to a real cause, like a clogged dryer vent or a failing motor or heating element. Fix that cause, or the new fuse will blow too.

What are common motor brush problems in tools and appliances?

Carbon brushes wear down over time. Signs include heavy sparking inside the motor, a burning smell, power that cuts in and out, or the motor not running at all. It's common in older vacuums, drills and saws, and brushes can often be replaced.

What reading should I get between a motor's windings and ground?

Insulation resistance between each phase and ground should be very high, typically in the megohms when tested with an insulation tester (megger) at the right test voltage. A low or falling reading means the insulation is breaking down and the motor should be checked before it's put back in service. A standard multimeter can't reliably test this.

How do I do basic circuit troubleshooting?

Turn the power off at the breaker and confirm it's off with a non-contact voltage tester. Then check for loose or damaged connections, and use a multimeter to test continuity, working through the circuit by process of elimination. If anything involves the panel or looks burned, stop and call an electrician.

What is a short circuit?

A short circuit happens when electricity takes an unintended, low-resistance path, usually hot wire to neutral or ground. Current spikes suddenly, which trips the breaker or blows the fuse. Repeated shorts mean damaged wiring or a faulty device.

What is an open circuit?

An open circuit is a break in the path, like a broken wire, a loose connection or a switch in the off position, so electricity can't flow and the device doesn't work.

What is electric current, and how is it measured?

Current is the flow of electric charge through a circuit. Its basic unit is the ampere, or "amp."

What tool measures electric current?

An ammeter. Electricians usually use a clamp meter, which measures current by clamping around a single wire without disconnecting it. Many multimeters can also measure smaller currents directly.
