"I am an Electrical Engineer by education and trade, working for several high-tech firms in Silicon Valley over a 45-year career, so I've never felt the need to call an electrician. But I know my limits and repairing an electrical open circuit routed in underground conduit is one of them. After trouble shooting the issue, I knew there was a break in the line so I called Mike at M3 electrical. He put me on his schedule, showed up on that date (even a little early) and in less than two hours had the issue fixed. Not only that, but he advised the type of 2-wire Romex that had failed was not the proper wire for an underground application. He pulled about 75 feet of the proper wire through the conduit and even installed a junction box at my street light for a clean installation. Costly you think? Not in my opinion! If I ever need electrical work done in the future, Mike is the guy I will call. I suggest you do as well. Mark S. A very happy customer"

"Dr. Wattz Electric came in the same day he contacted me and provided a quote I could not refuse. We arranged for him to come back a few days later to install various switches and outlets in my garage as well as 3 Ring security camera/floodlights around my home. He delivered on the various activities and assignments with distinction. He installed everything perfectly. I will use him again in the future."

"The Huft technicians knew their stuff. They arrived promptly in the morning, removed the existing units, and installed the new units without a hitch. The systems were up and running by the afternoon, and have served me well over the last three years, working great in both summer and winter. Huft provided free semi-annual maintenance visits for two years. There was a minor problem with the rooftop unit recently, and they repaired it under warranty at no charge. The cost was not cheap, but for me it was worth it to go all-electric."

Electrical questions, answered by experts

You can install a three-prong outlet without connecting any ground and plug in three-prong electronics into that outlet. The devices will function normally, but you won’t get any of the protection that grounding provides, so there’s an increased risk of serious problems if something goes wrong.

GFCI stands for Ground Fault Circuit Interrupter, a standard safety addition to home power outlets. In rooms where moisture is more likely, like the bathroom and kitchen, GFCI outlets stop the current when certain kinds of shorts are detected, preventing shocks. Both GFCI and the similar AFCI (Arc Fault Circuit Interrupter) outlets are polarized and have clear indicators on the receptacle where hot wiring should go.

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.

No, it is not safe to use an outlet that sparked. A spark from an outlet could indicate a short circuit, loose or frayed wiring, or other serious damage. Continuing to use an outlet that sparks can increase the risk of electrical shock, electrical fires, and other hazards. It's important to turn off the power to the outlet at the circuit breaker if possible and avoid using the outlet until a licensed electrician has inspected and repaired it.

Yes, but our analogy with the water hose doesn’t really work here. You see, electrical flow isn’t constant: It ebbs and flows like waves, coming in pulses of power. Hertz measures the rate of change in the flow of electricity, or how often it ebbs and flows. For example, 60Hz means that the electrons pulse through wiring 60 times per second. When they are pulsing, they’re in a brief retreat. Almost all United States equipment is rated for 60Hz.
