Electrical questions, answered by experts

Single-pole light switches are the most common light switches on the market. Their simple features make them easy to install and use. For more powerful applications that require 30 or 40 amps, you may need to use a double-pole switch. Some homeowners may want multi-way switches like three-way or four-way switches to control a light fixture from opposing ends of the room.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

There are a few reasons your lights may be on, but the rest of your electrical outlets and appliances are not working. The first is that while one circuit blew out, the lights may be on another circuit than your other electrical fixtures. Alternatively, your powerless appliances may be plugged into a GFCI outlet that was tripped and needs to be reset. If these issues aren’t responsible for the problem, you may have dead outlets or a wiring issue. Either way, you should contact an electrician to identify and fix the issue.

If you need to run a wire from the meter to the breaker box, start by turning off the power using the main switch to avoid injury risks from live wires. Then, locate the ground wire from your meter and connect it to the ground bar of the breaker box. Connect the neutral wire using the same method to improve your circuit efficiency.

Next, locate the hot wires running from the main switch to the meter. To connect them to the correct terminals from meter to breaker, unscrew the nuts of the breaker hotwire terminals, insert the positive hotwire, and ensure it’s firmly attached. Finally, secure the wires with electrical tape and wire tie cables before re-securing your breaker box. Keep in mind that this process can be dangerous, so don’t hesitate to hire a local electrician.

Yes, a light switch still has power even when switched off. Switches only interrupt or continue the flow of electricity into a fixture or outlet; they do not shut off the power flowing into the wire. The only way to shut off power in a light switch is to turn off the power at the circuit breaker.
