"Paul arrived on time, quickly identified a workable solution to my electrical need. He noted equipment and wiring I already had installed and used that knowledge to give me an estimate that was much less than previous estimates. He is very knowledgeable, got the job done quickly and I would heartily recommend him for any electrical work."

"I will recommend Champion Electrical Services to anyone interested in hiring competent, reliable and honest electricians. It starts with salesmen Jayron Diaz who submitted the job estimate to upgrade an electric panel to code. There was no surprise costs. Jayron was very professional and honest about the work. On the day of the service, Matt Wood and Sean arrived at the scheduled time as promised. Matt explained what they were going to do, how long it would take, and if I had any questions. Matt estimated the job would take approximately 6 hours. It actually only took 4 hours from start to finish and that included cleanup and minor repairs. I think Champion did an awesome job and I will call upon them for my next project."

Electrical questions, answered by experts

To install an outlet from existing wiring, you’ll need to choose a location where you can already access existing wiring. The easiest way to do this is to install an outlet on the other side of the wall of an existing outlet. 

Since the wiring is already in place, all you have to do is connect a new cable to the existing wiring and then connect the correct wires through the wall—to the new electrical outlet. Place your new outlet into the opening in the wall and then connect the correct wires to the appropriate terminal screws.

No, it doesn’t matter which of the two wires goes on each of the two switch terminals. Just be sure to put the ground wire in the correct terminal. The ground wire is either green, bare copper, or green with a yellow stripe. The other wires are hot wires and are typically black. They can be used interchangeably.

It’s possible to distinguish a positive black wire from a negative black wire if you know what type of circuit the wires are in. If it’s an alternating current (AC), then black wires are positive. If it’s a direct current (DC), then black wires are negative. 

Sometimes, a circuit has two black wires. In that case, the positive black wire will be solid black while the negative black wire will have a white stripe on it. If you’re still unsure, you can use a multimeter to check.

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

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.
