"My husband and I highly recommend Jeremy. We had power issues and Jeremy walked us through everything that was going on. He went over the pricing and stuck to it. He is quick to respond to communication. We are very happy with the work he and Austin did to correct and upgrade our electric service. We will definitely be using him for future electricity needs and recommend him highly!"

"This was by far the best contractor experience I’ve had in many years. Rob is friendly, knowledgeable and professional. He was able to work within my budget and kept me informed during every stage of the process. My generator was ordered and installed in only one week, which was also very impressive. I would highly recommend Buckley & Son Electrical Contractors."

"Roberto Suarez ( A and A Electric) was excellent. He showed up in the pouring rain and installed the wiring for an electric range on a Mobil home. The job entailed running cable approximately 50 feet under the unit in pvc, installing the outlet and connecting it to the breaker box. He gave me the best quote, did excellent work and was a total gentleman! All on a Sunday in a torrential storm. HIGHLY RECOMMENDED!!"

Electrical questions, answered by experts

It’s not a good idea to mix LED and incandescent Christmas lights if you can avoid it. LEDs and incandescents can have significantly different electrical current needs. This difference can lead to a higher risk of problems and failure for both light strands. When possible, switch all your lights over to one kind or the other for the best results. Do not connect the different types of light strings to each other, and avoid linking them to the same circuit. 

Many wire nuts can accommodate three wires of various gauges; you should check the packaging of the nut to confirm you are buying the correct size. In addition, there are screw terminals that accommodate various numbers of wires; these might also be called “terminal blocks,” and exist to connect multiple wires. 

Using a wire stripper/cutter, strip about 1/2 inch to 1 inch of sheathing from electric wires, depending on the application. A self-adjusting wire stripper/cutter works best, but a standard wire stripper/cutter with holes for different gauges of wire works as well to cut and strip away the sheath without damaging the copper wire inside.

A piggyback circuit breaker, also known as a tandem or double-stuff breaker, combines two separate circuits into a single slot in a breaker panel. This design allows adding more circuits without a larger panel, making it a space-saving solution. Each breaker in the piggyback unit operates independently, protecting two circuits in one standard breaker slot. This is especially useful in older panels with limited space for additional breakers.

A faulty light switch can trip a breaker due to circuit overload or a short circuit. A faulty light switch may not always trip a breaker, so don’t use that as your only sign that something’s wrong. Always investigate the cause of a switch that isn’t working properly, feels hot to the touch, or is making unusual noises.
