Electrical questions, answered by experts

Smoke detectors come in two different options: hardwired or battery-operated. While hardwired units are attached directly to the home’s electrical system, a battery-operated smoke detector only needs a simple battery for operation and can be placed virtually anywhere in your home. Some homeowners may mistakenly think their battery-operated units are hardwired in because all their units are interconnected, but many battery-operated units can operate within a smoke alarm network in your home.

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.

Appliances in the United States are often bigger than other parts of the world.

Updating your old outlets, or adding grounding clamps to a metal box are two methods. Each home is different. Consult an electrician for advice on grounding a wire without doing extensive work to dig into the ground.
