Electrical FAQs, answered by experts

It's possible to get power from an outlet for a light switch. However, you must install additional wiring to get current from the outlet to the switch and from the switch to the load it will control. Also, you must ensure that the outlet's electrical circuit can accommodate the additional demand. 

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

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.

A ceiling light will usually have two or three wires: black, white, and sometimes green. Black wires are positive, or hot, while white wires are negative, or neutral. The green wire is the grounding wire. 

When you’re wiring the light, connect black to black, white to white, and green to the grounding screw.

While washers and dryers do not require a GFCI (ground fault circuit interrupter) outlet to function properly, electrical codes often mandate their use for safety. The National Electrical Code (NEC) requires GFCI protection for all outlets within six feet of a water source. This means a washer and dryer must be plugged into a GFCI outlet if they are installed in locations like a laundry room, utility room, garage, or basement. In other areas without a nearby water source, there is no specific requirement, but using a GFCI outlet is still recommended for extra peace of mind. It is always best to consult your local codes and regulations to ensure compliance and safety.
