Electrical questions, answered by experts

GFCI stands for ground fault circuit interrupter, which means it has the ability to detect a ground fault and shut the circuit down before it creates hazards. General breakers may also do that because ground faults can cause overloads, but they’re more focused on amp overloads from any cause. GFCIs are often installed in specific outlets, but breakers can come with GFCI capabilities built in for broader ground fault protection.

Yes, the National Electrical Code (NEC) requires that outdoor Christmas lights be plugged into a ground-fault circuit interrupter (GFCI) outlet to prevent hazardous electrical shocks or an electrical fire. It’s a code violation to plug outdoor Christmas lights into a non-GFCI outlet, so be sure to follow these guidelines for a safe and successful installation.

Yes, many professionals offer surge protection to safeguard equipment from power fluctuations.

Most 200-amp panels are allowed 40 breaker slots, though they can accept more circuits with the installation of tandem breakers. To determine the right number of breakers for an electrical panel, panel manufacturers will give their products a rating. That rating is used to limit the number of electrical circuit breakers on the panel. You can check your panel for a rating or ask your electrician to weigh in.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.
