"I hired Brite Electric to expand the electric capacity at my house and to add a 240 volt outlet for my ev car charger. Pete did an excellent job performing these tasks in a timely manner. He effectively communicated in detail the job tasks and answered all my questions. Pete was dependable and did not vary above the quoted price. I would definitely call Brite Electric for any future electrical work."

"I highly recommend Thundercolt Electric. Gerardo came out, provided a bid and when I advised I was ready to get started they quickly got started on the project which included recessed lighting, new electrical outlets and switches, changing out electrical outlets and light switches, installing a surge protector for the home, installation of ceiling fans and a ring doorbell. Thunderbolt did an excellent job and I would hire them again for any work I may have and Iâ d recommend them to family and friends."

"Outstanding communication and very professional service. I would highly recommend Mr. Electric. Received both e-mails and texts on appointment to include a photo and short bio of the actual electrician (Brad Mason) who would be doing the work. Wish all home service providers did the same. Brad was on time (actually a few minutes early). He installed 30AMP breaker and associated RV plug in our garage. To avoid any sheetrock repairs it was necessary for him to drop the line to the house electric panel through a wall with foam insulation, with very limited head/body clearance for him to work. No mess left behind from the actual plug installation on another wall."

"I recently had a light fixture installed in my office and an electrical outlet relocated to a different area, and I couldn’t be happier with the results. The electrician was professional, punctual, and paid close attention to every detail. The installation was clean, the work was completed efficiently, and everything looks and functions perfectly. It’s clear they take pride in their craftsmanship and customer service. I highly recommend them to anyone looking for quality electrical work. Thank you for doing such an amazing job!"

Electrical FAQs, answered by experts

Outdoor outlets should be at least 15-amp, but preferably 20-amp. The exact rating will depend on the electrical load of the devices that will be plugged into the outlet and the capacity of the circuit. It's important not to overload the circuit, which can cause safety hazards such as tripped breakers or electrical fires. In general, a circuit rated for at least 20 amps is recommended for outdoor outlets, while each outlet should be rated for at least 15 amps.

Grounding is an essential part of installing an electric fence. Without grounding, the electrical circuit will be incomplete. That means the fence won’t work and will fail at delivering shocks upon impact. Even grounding the fence improperly can cause faulty shocks, if any. To ground the fence, you will need to use ground rods, ideally made from copper or galvanized metal, that are at least 4 feet high, for best results.

Yes, a water leak poses a major fire risk at your home because water is a conductor of electricity. Water that comes into contact with sparks or electrical wires can instantly ignite flammable materials. Additionally, any type of exposure to water can cause wires and other electrical components within your home to corrode. When assessing categories of water damage, it's important to know that even a small amount of moisture near wiring could cause sparks that lead to a fire.

On average, the cost to wire a new home ranges from $2 to $5 per square foot. The cost to rewire a house is around the same, ranging from $2 to $4 per square foot. Often, though, new wiring comes with lower overall costs since it’s much easier to access a home’s foundation. 

A ground wire is not required for GFCI to work. A ground is a third wire in an outlet in addition to the live and neutral wires. It serves as an escape conduit for electricity in case of a short circuit. If a ground wire is present, installers should connect it to the appropriate terminal. Otherwise, a GFCI will work fine without it.
