Electrical FAQs, answered by experts

A two-way switch is also called a single-pole or single-throw switch. These switches only have an on-and-off function and only control a single light or series of lights wired together. A three-way switch has no “on” or "off” position and works with a second switch in the circuit to control a single light or light series from two locations.

Using a wire stripper/cutter, strip about 1/2 inch to 1 inch of sheathing from electric wires, depending on the application. A self-adjusting wire stripper/cutter works best, but a standard wire stripper/cutter with holes for different gauges of wire works as well to cut and strip away the sheath without damaging the copper wire inside.

A breaker won’t always trip if an outlet burns out. If the outlet is overloaded or has a short circuit, the breaker is designed to trip and discontinue power to the outlet. However, some wiring problems that can burn out an outlet may not cause the breaker to trip, so don’t rely on it as a signal that something is wrong.

The purpose of pigtail wiring is to connect multiple wires to a single terminal on a device. Pigtailing involves splicing a short length of wire, called a pigtail, into the multiple wires that need to be connected. The pigtail wire is then connected to the single terminal on the device, allowing all of the wires to be connected at once. This practice helps to simplify the wiring process, reduce clutter, and ensure a secure and reliable electrical connection.

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.
