Electrical questions, answered by experts

You can run a small or basic standard-size refrigerator on a 15-amp circuit. But you should plug a modern, standard-size refrigerator into a 20-amp dedicated circuit. The refrigerator needs to be on a dedicated circuit, meaning it is the only appliance and outlet on that circuit breaker. This method prevents tripping the breaker and reduces the chance of an electrical fire

If one plug in your outlet works but the other doesn't, it could be due to a few reasons. The outlet might have a loose or damaged internal connection on the non-working side. Another possibility is that the outlet is a split receptacle, with one half controlled by a wall switch that might be turned off. Additionally, debris or damage inside the non-working plug could prevent a proper connection. If you can't identify the issue, remember to prioritize safety. Replace the outlet or consult a professional electrician to ensure safety and proper functionality.

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.

If you have a tank-type electric water heater, it runs regularly to keep the water at the desired temperature. If you live in a home where you don’t use much hot water, it could seem wasteful to run power to heat water that you’re using infrequently. You could save some power by using a smaller tank, insulating the tank, or lowering the temperature of the water heater.

A GFCI outlet can be 15A or 20A. The average American home power outlet is 15A.
