"We had an issue in our house, with some of our electricity being off and some remaining on. we were told, on the phone, that it could be one of a few things. Don and Pat came the next day, promptly at the time we were told. They checked out the system and told us that it was a line issue. Don told us that PSE&G should take the amount of his bill off our electrical bill. His bill was reasonable, even if we weren't able to have it deducted. We would hire DLP again."

"My experience with Apollo Electric was wonderful. I needed some normal electrical work done, and also some detailed more involved work. He handled everything with care as if it was his own home. He was very detailed oriented, neat, clean and very honest. Mike worked hard during the entirety of the job, I was very pleased and I would call him for any job I need involving electrical work for the future"

"We had an excellent experience with this electrician at our 120,000 sq ft office building. He came out to perform repairs and upgrades on our electrical systems and delivered truly professional, high‑quality workmanship from start to finish. His knowledge, attention to detail, and clear communication made the entire process smooth and efficient. It’s not easy finding someone who can handle large‑scale commercial electrical work with this level of skill and reliability. He showed up on time, worked safely, and made sure everything was done correctly the first time. I highly recommend him for any commercial or residential electrical needs. Outstanding service and professionalism"

Electrical FAQs, answered by experts

Yes, a faulty or broken light switch can be a serious fire hazard. Malfunctioning switches often result from loose wiring, exposed connections, or other electrical problems that can cause overheating or sparking. Warning signs include crackling, popping, or hissing sounds when you flip the switch, which indicates live electricity that could ignite nearby flammable materials. If you suspect your light switch is faulty, immediately turn off the power at the circuit breaker and contact a qualified electrician to remedy the issue.

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.

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.

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.

Yes, it’s safe to strip a wire if you follow the proper safety precautions. First and foremost, you must always disconnect the power and never try stripping a live wire. Using wire strippers is another safety precaution, but don’t forget to keep your fingers away from the blade. It’s also critical you only remove the insulation and not accidentally cut into the conductor, which is unlikely as long as you’re using the right-sized wire stripper.
