Electrical questions, answered by experts

You should aim to replace your electrical outlets every 15 years, although some GFCI outlets can last as long as 25 years. On the other hand, outlets can go bad much earlier if:

  • The wiring is in poor condition.

  • Your circuit is overloaded.

  • There are loose plugs in the outlet. 

  • If the outlet wasn’t installed properly. 

  • If the outlet wasn’t grounded. 

How far you can run underground electric depends on the wire gauge (generally AWG) and the circuit voltage. Too much voltage drop in an electrical circuit can negatively affect performance, so the smaller the voltage drop, the better. Ideally, it shouldn't exceed 3%. The smaller the wire and the longer the run, the more significant the voltage drop. 

For example, with a 120-volt circuit, you can run 60 feet of 12 AWG cable without losing more than 3% voltage. With a 240-volt circuit, you can run 120 feet of 12 AWG wire while maintaining a voltage drop of 3% or less.

Pool pumps use a lot of electricity, depending on the size of the pump, how energy efficient it is, and how long it runs. Most residential pool pumps use about 1 kilowatt-hour of electricity every hour they run, which makes them one of the biggest energy uses in a home. Lower the amount of electricity your pool pump uses by choosing an energy-efficient pump, running it only for the time needed to keep the pool clean, and sizing the pump to your pool.

You can bury underground electrical wire six inches deep—but only if you use a rigid metal electrical conduit. For rigid, non-metallic conduits, bury the wire at least 12 inches deep. If using an underground feeder cable rated for direct burial, you'll need to place it at least 18 inches deep, as it has no conduit for extra protection.

Yes, it’s safe to strip a wire if you follow the proper safety precautions. First and foremost, you must always disconnect the power and never try stripping a live wire. Using wire strippers is another safety precaution, but don’t forget to keep your fingers away from the blade. It’s also critical you only remove the insulation and not accidentally cut into the conductor, which is unlikely as long as you’re using the right-sized wire stripper.
