Electrical questions, answered by experts

Yes, you can use a 3/0 AWG wire for a 200 amp service, but only if it is made of copper, as 3/0 copper wire has an allowable ampacity of 225 amps. If you are using aluminum or aluminum copper-clad wire, you need to use at least 4/0 AWG.

An electrician can handle wiring issues with the garage door opener, like faulty connections, circuit problems, or sensor malfunctions, but they’re not the right person to hire for mechanical repairs. Garage door specialists handle things like broken springs, tracks, and panels, while electricians step in if there’s an issue with power supply, motor function, or safety sensors that aren’t responding correctly.

Yes, an AFCI (arc fault circuit interrupter) outlet also has line and load terminals, although it uses different technology than a GFCI and offers a different kind of protection. AFCIs monitor for internal arc faults, a type of wiring problem that can start an electrical fire.

A piggyback circuit breaker, also known as a tandem or double-stuff breaker, combines two separate circuits into a single slot in a breaker panel. This design allows adding more circuits without a larger panel, making it a space-saving solution. Each breaker in the piggyback unit operates independently, protecting two circuits in one standard breaker slot. This is especially useful in older panels with limited space for additional breakers.

You should never wire neutral and ground wires together at a light switch. Not only is it unsafe, but it’s also incorrect. The neutral and ground wires perform separate functions in an electrical circuit and should never be swapped or wired together at a light switch, light, or outlet.
