"Start to finish the A To Z Electrical Company is the best electrical team we have hired. Millie is such a pleasure to work with. She is efficient, courteous, and friendly. She helps to make things work seamlessly. Bob Iovino understood exactly what needed to be done and did everything in a professional manner. He squeezed me in although he had a very busy schedule. He is courteous, friendly, and in no time he had the job done and it was done right. It truly was a pleasure doing business with him and the company. We recommend them highly."

"J&M Electric was great! They updated my electric panel box, fixed some light switches, and installed a beautiful chandelier/ceiling fan and new light fixtures outside. The whole team was professional and courteous. The fees for all the work done was fare! I recommend them to anyone needing electrical work done and will use them again when the need arises!"

"Dave was willing to work with my limited availability. He created route from my electrical panel to the garage that was most direct and efficient, saving me money on the cost of supplies. I have already spoken to him about another project I need an electrician for."

Electrical questions, answered by experts

No. Blue wires and black wires are different. Even though both are used as hot wires, they serve different functions. Black wires are far more common in residential properties. They are always hot, can be positive or negative, and usually carry electricity from a power source to an outlet. Blue wires have a specialized usage in residential properties, generally as traveler wires, and are more common in commercial properties.

There are three main wires on a doorbell, typically color-coded white, black, and green, that are connected to a transformer box in your home. One wire runs to the doorbell button, another wire runs to the door chime, and the third wire runs between the doorbell button and the door chime.

Homeowners should avoid replacing a circuit breaker without turning it off. While you technically can replace a circuit breaker without turning off the main breaker—and professionals can and do—it’s only safe for electricians to use this process. Working with a live panel is extremely dangerous if you don’t have experience working with electricity. Always follow safety measures to avoid electrical shock.

You shouldn’t try to touch the electric fence, as it will shock you. Typically, the shock is low enough to be uncomfortable to humans or animals that come into contact with the fence. But an electric fence with high voltage, or a faulty fence, could shock you and cause serious injuries when touched.

The Occupational Safety and Home Administration (OSHA) requires an electrical panel to have a minimum of three feet (36 inches) of room from the front of the panel to the closest obstacle. In this case, the word obstacle refers to nearly everything, including walls, machines, and other fixed objects. Additionally, panels require at least 6½ feet of headroom in the area directly in front of the fixture. These requirements help ensure safe use of the panel and allow electricians plenty of room to work.
