"Kope Electric just finished installing a Generac generator at my house and their work was top notch. They actually got me in their schedule 1 week early and finished as timely as they said they would. I highly recommend them to anyone interested in a generator."

"Excellent job. The owner was able to diagnose the problem with our generator. He made a sound recording and video documenting the problem and sent it to the generator company enabling us to receive new parts under the warranty. Mr. Byrne then installed those parts and fixed the generator. We have since used New Grange for all our electrical needs."

"The experience I had with Antonio and his men were nothing but spectacular and world class… Antonio came personally to my home to scope out the project, suggested what I needed, and his men delivered they were professional. They were courteous. They cleaned up after themselves, and they were very cautious in respecting my home even to the point where they put drop cloths down on the floor because it was raining outside….. This ladies and gentlemen is how you want to be treated as a customer with the utmost respect, courtesy, fairness, and knowledge of the job!! thank you Antonio and the two gentlemen who came and did the electrical work from my house House you guys were amazing… if I ever need anything else from my home as far as electrical, you guys will be the first person I call.. I wish I could’ve gave them 10 stars… thanks fellas all the best.. Dino"

Electrical questions, answered by experts

The cost of fixing faulty wiring depends on the type of repair required. Replacing an electrical service line, for example, can cost up to $500. Rewiring an entire house will cost at least several thousand dollars. Replacing old wiring like knob and tube wiring will be even more expensive, but fortunately that kind of outdated wiring is fairly rare. Always get an estimate from a reliable electrician to learn the cost details. 

Do not touch electrical wires in your home without first turning off the power at your circuit breaker and testing the wire with a voltage meter or multimeter. Electricity still flows through wires even when a light switch is powered off, and touching wires with the switch on can result in electrical shock.

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.

Local building codes typically require conduit around exterior wiring. Conduit protects the wire from moisture, extreme temperatures, sun exposure, and harsh weather conditions to prolong its lifespan. When a wire is worn out, it can be dangerous as the risk of electric shock or fire increases.

In many cases, yes, upgrading your electrical panel can lower your electric bill. Upgrading an outdated electrical panel can make your home more energy-efficient, so you consume less electricity and spend less on utility bills. However, to see these savings, you’ll need to invest quite a bit. On average, installing a new electrical panel costs $1,200 to $2,000, with most people paying around $1,600.
