"Lowest price among multiple quotes and significantly more attention to detail and the least visible and least intrusive installation of new wiring from the existing panel. Would definitely recommend and use Mark H. Anderson Electrical Services again!"

Customers say: Quality work

"From start to finish, Long Electric had our backs. We didn't have to hire sub-contractors or to obtain permits -- Long Electric took care of everything. Our go-to person in the main office, Melissa, answered all of our questions and kept us apprised of everything we needed to know. Everyone we had contact with throughout the installation project treated us with the utmost in professionalism. Not only will I call upon them for future electrical needs, I have referred Long Electric to a friend who is also interested in a whole house generator."

"Ash Electric installed a level 2 Tesla charger for us. We went with Ash as their quote was very reasonable. From the beginning, it was clear that customer service and communication were both excellent. Noah kept me informed at every step and was honest and prompt with responses. Even when he was away from home, he kept in touch. Installation was done by Vince who was extremely professional and did the job perfectly and in a reasonable time. Inspection was scheduled by Noah and went through quite easily. I would say Ash Electric went above and beyond what was required to satisfy a customer. Most companies could learn a thing or two from them. If you are planning on installing a charger, look no further. I would highly recommend them to anyone."

"I had a wonderful experience with Electrical Connections. My project ended up being much larger than I anticipated it would be and they were excellent at explaining everything and helping me understand what needed to be done. Customer service was top notch and clearly a priority for everyone I talked to from the scheduler to the owner of the company. Brian was excellent and stayed until the job was done even though it made an extra long day for him. Highly recommended!"

Electrical questions, answered by experts

Doorbell wires typically won't spark because they carry low voltage. However, if there's a short circuit or damaged wiring, sparking could occur. Always turn off the power at the breaker box before working with doorbell wires to prevent any risk. If you notice any sparking, it's a sign of a problem that a professional electrician should address.

If you have a garage heater that is 1,500 watts or more, it will need its own breaker. As a good rule of thumb, no appliance should exceed 1,500 watts per outlet for best outcomes. Consult a local garage heating service to determine the power needs for your outdoor or indoor space.

Although homeowners can turn off a breaker, it’s vital to follow safety precautions when doing so to prevent serious and potentially fatal injuries. For instance, you want to ensure there is no water on the floor when you touch the breaker and wear protective gear such as safety glasses. Anytime you deal with anything electrical, it’s always best to be as safe as possible.

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.

Though they may seem similar at a quick glance, outdoor electrical outlets are different from indoor electrical outlets in that they have extra safety precautions to prevent electrical hazards. These include GFCIs, which some indoor outlets have, and a watertight cover that allows you to use electricity from the outlet even on a rainy day.
