"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."

"Cawiamca Heating, Cooling, and Electrical was professional, knowledgeable and nice from the very first call. The owner Ron came out within a day to scope out the project and provide very reasonable quotes. From there, he quickly scheduled the install of the new Furnance and had his team out very quickly. His team worked diligently, were knowledgeable and very nice. They were efficient and clean during the install, leaving no debris leftover. I would highly recommend using this company as I know I will continue to going forward."

"If you are looking for an excellent electrician, start with this company first! I found Ben to be knowledgeable and professional. He did an inspection of our electrical issues and came back promptly and took care of the repairs. He made sure that everything was safe. I also feel that he did not overcharge me. He promptly provided a report to the Bldg Inspector, which was required for occupancy after our fire."

Electrical FAQs, answered by experts

Some types of electric fireplaces use more electricity than others. Models that produce 1,500 watts will have more of an effect on your heating bill than 750-watt models. 

Electric fireplaces use an average of $1.85 of electricity every eight hours. These minimal operational costs aren’t likely to make a big difference in your electric bill—unless you’re using it as a primary heating source for your home and it’s running most of the time.

Yes, you can use a 3/0 AWG wire for a 200 amp service, but only if it is made of copper, as 3/0 copper wire has an allowable ampacity of 225 amps. If you are using aluminum or aluminum copper-clad wire, you need to use at least 4/0 AWG.

Technically, an outdoor outlet can be on the same circuit as an indoor outlet, but it's generally not recommended. Outdoor outlets should ideally be on a dedicated circuit that doesn't share power with other indoor or outdoor outlets. This helps ensure that the outdoor outlets are able to handle the additional electrical load without overloading the circuit. Additionally, outdoor outlets are often exposed to the elements, which can increase the risk of electrical shock and other hazards. If you must have an outdoor outlet on the same circuit as an indoor outlet, be sure that the circuit has the capacity to handle the additional load.

While you can technically live in a home while it's being rewired, prepare for some debris and dust if your electrical contractor needs to remove parts of walls, floors, and ceilings to access wires. If you stay home during the project, ask your electrician to cut the power supply to all exposed electrical wires to keep your family safe.

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.
