"Mr. Klaus arrived at my house within 2 hours of calling. He made me aware of everything he had to check out and the possibilities of what could be wrong. Within a very short amount of time he was letting me know what he found and what he would have to do to fix the problem. He gave me different options and recommended the best solution to me. By the end of the day my kids had electricity back in their bedrooms and it did not cost me anywhere near what most other companies quoted me to even come and diagnose the issue. I recommend Resolute Electric to everyone out there reading this! Absolutely the most knowledgeable, courteous, and prompt company I have had to deal with in any of my home repairs."

"Mark from Duke's Electrical Services was recommended by a friend in the home improvement business whose referrals have always been A+, and Mark certainly lived up to that reputation. Mark and his son were professional, punctual, and communicative. They texted before arriving and showed up exactly on time. Mark performed a thorough electrical inspection, took photos, and reviewed everything with me so I understood the condition of our system. I also asked about a few smaller projects, including a dock light switch and a deck remote-control switch that weren't working. Mark followed through on his promise to return, contacted me within a week, and scheduled the repairs. During that visit, I added two more switch replacements, and they completed all three jobs in under an hour. What impressed me most was their attention to detail. After finishing, they vacuumed the work area. As someone who appreciates cleanliness, that meant a lot. Professional, efficient, cleanliness, very rare find."

"On August 2025 I had two Hunter ceiling fans installed by Mike and was very pleased with the results. The installations were done efficiently and professionally, with both fans mounted in the second-floor loft and bedroom with 8’ ceilings. Communication was clear throughout the process, and he made sure everything was working perfectly, including the wall controls for each fan. I highly recommend their services for anyone needing reliable and quality electrical work."

"I hired W B Lighting Rods/William Burden to install lightning rods on my home. I spoke to William on a Monday and by Thursday before 1 PM the lightning rods were installed on my home. William explained everything he was going to do before he did it. The lightning rods were affordable and most of all it gives me peace of mind knowing that my home is protected against lightning strikes and fire damage. I couldnâ t be happier with this company!!"

"Very professional and efficient. Arrived timely, very knowledgeable, and efficiently repaired appliance. Our General Electric large refrigerator was not properly cooling. Found door leakage, ordered the part, and returned to replace the seal. No markup on the part, no added time to repair - entire transaction was very fair. Could not ask for a better experience."

Electrical questions, answered by experts

Many wire nuts can accommodate three wires of various gauges; you should check the packaging of the nut to confirm you are buying the correct size. In addition, there are screw terminals that accommodate various numbers of wires; these might also be called “terminal blocks,” and exist to connect multiple wires. 

When power is restored to your home, the transfer switch will return to utility power after about 10 seconds. Your generator will then run for a few more minutes to cool down before automatically shutting itself off. In most situations, your home will stay powered by the generator for at least five minutes, even after your power comes back on.

You can install a dimmer switch on almost any light as long as the switch, bulb, wiring, and wattage are compatible. Check what kind of light you have, the type of light bulb, and the total wattage of the bulbs to ensure your dimmer is a match. You’ll want to choose a non-neutral wire dimmer if you don't have neutral wiring. Homes built before 1985 that don't have updated electrical systems may not have neutral wiring.

Smart light switches are designed to work with most traditional light fixtures and wiring. However, there are several compatibility factors to consider. Some smart switches require a neutral wire to function, which may not be present in older homes (typically built before 1985). If you plan to use a dimming feature, ensure your LED bulbs are specifically the dimmable type. Additionally, a stable Wi-Fi connection is necessary for remote control, though some models may use other standards like ZigBee, which would require a compatible smart home hub.

The NEC prohibits the installation of electrical panels within clothing closets. Closets are filled with flammable items like clothing, mothballs, shoe polish, plastic containers, and exposed light bulbs. If the panel develops a small electrical fire, it won’t take long to bloom into a real disaster. If you have an electrical panel in one of your home’s closets, move it as soon as possible with the help of a professional electrician.
