"Dylan was great! He responded right away, and explained my options clearly. He showed up on time for both the estimate, and for the work. The estimate was very reasonable, and I paid him more than he asked for, because I felt he deserved more. Very pleasant personality, and I enjoyed meeting him. If I ever need an electrician in the future, he would be the guy I’d call for."

"Wes knew what he was doing. My project was more challenging than normal. To install my antenna he had to work in the crawl space under the house and find the base of an interior wall. He got the job done and the results were I had great reception and he stayed with his original quote."

Electrical questions, answered by experts

With AC wiring, which is the kind most likely you’ll find at home, the black wire is “hot,” and the white is “neutral.” The bare or green wire is considered the safety ground wire. If you encounter DC wiring, it’s relatively easy to tell positive or negative wires apart. red wires are used to indicate positive voltage and black wires indicate negative voltage.

Labor, materials, job complexity, and urgency affect costs for switches and outlets; expect from $150 for simple sets to $600+ for significant upgrades.

Yes, the National Electric Code (NEC) requires at least one GFCI outlet in each sectioned-off portion of an unfinished basement, partly to ensure a power source is available for a sump pump in case of flooding. If you install multiple outlets in your unfinished basement, all of them must be GFCI-protected. For finished basements, standard outlets are generally permitted, but at least one GFCI outlet is still required per circuit. Keep in mind that local municipalities may have additional codes, so it's best to consult a licensed electrician to ensure your home is fully compliant.

Old electrical systems may have more problems than newer ones. In some cases, like if your home has aluminum wiring, it may be necessary to update your electrical system. You should also update your home’s wiring if it still has knob and tube wiring, which is considered dangerous by modern building standards. If that applies to you, get in touch with an electrical professional near you to obtain a quote.

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.
