"DC electrical did an awesome job. They rewired the knob and tube in my home with minimal impact to my plaster walls. The job wasn’t easy and they spent all the time required to get it done right. I wholeheartedly recommend them."

"This was the worst experience i have ever had with a company. They came and damaged my house and kept us without AC for days. They admitted to the extensive damage and went weeks before attempting to repair it. The services were never fully completed and they were paid over 90% of the job. I disputed the last 10% and provided overwhelming evidence of their negligence. And after a year their last ditch effort was to send collections letters. Don't walk, RUN from this company. I will provide pics and my my experience to anyone who is planning on using this company. Used to be family owned and was amazing. Second they sold it went downhill fast."

"I had an electrical issue in my kitchen and the power to main floor went out. I ended up having a back switch that needed to be replaced. I was quickly contacted to understand the issue, and DLP Electric was willing to come out today, however I had already just hired a technician from another company to handle (right before I spoke to DLP). Having said that, DLP Electric was professional and very helpful, and I would hire them if I ever needed electric work performed in my house. Great customer service and very responsive."

I offer a one year warranty on parts and labor (excluding lamps)

"Overall, Dave's service was excellent. Dave was punctual, professional and provided a fair price. He was available via chat to agree on appointments and helped me with the town permit. He upgraded my kitchen lighting by adding more circuits, running two electrical lines for the cooktop, wall oven, and updated the electrical panel. He cleaned the area after work was done. He is friendly and courteous. I highly recommend Dave."

Electrical questions, answered by experts

Systems should be checked every 2-3 years or whenever signs of age appear, maintaining network integrity and safety at all times.

It's recommended that you only use your circuit breaker for your water heater. Tacking on additional appliances, especially large ones like refrigerators, can overload the circuit and lead to electrical fires. Therefore, it's best to have separate circuits for each major appliance, particularly continuous load appliances, which use a lot of energy over prolonged periods of time.

The most common reason a GFCI outlet would trip even when nothing is plugged in is if there’s a problem at the circuit breaker end. This could be an overloaded circuit, with too many appliances plugged into it, or another type of fault. If a GFCI outlet keeps tripping, it can also be because it is faulty and needs replacing.

A two-way switch is also called a single-pole or single-throw switch. These switches only have an on-and-off function and only control a single light or series of lights wired together. A three-way switch has no “on” or "off” position and works with a second switch in the circuit to control a single light or light series from two locations.

A wire stripping tool is the easiest way to strip sheathing or plastic insulation from electrical wires. A self-adjusting wire stripper cuts and removes the sheathing without damaging the core wire.
