"Had an electrician out to give me an estimate on replacing my electrical panel. Decided against replacing it because that wouldn't have solved my issue. My house was built in the 60's so it needs all new wiring. I just had him show me which outlets were on each of the channels so that I could spread out my devices that needed a lot of power, specifically my space heaters."

Electrical questions, answered by experts

A gas stove doesn't always need a dedicated circuit. Unlike an electric range, which uses 240 volts and requires a 240-volt receptacle, a gas stove only uses 120 volts. In some cases, your electrician will need to replace the existing two-pole circuit breaker with a single-pole circuit breaker as well as swap out the existing 240-volt receptacle with a 120-volt replacement.

You should hire a licensed electrician who is insured to perform any electrical work on your home, including lighting installation. States have different requirements for licensing and certifying electricians, so use Angi’s state licensing tool to review local guidelines.

Here are a few questions to ask electricians before hiring:

  • How many years of electrical experience do you have?

  • Are you licensed, bonded, and insured?

  • Do you work with subcontractors?

  • Do you provide a guarantee or warranty on your work?

  • What is the timeline for completion?

  • How do you handle change orders?

  • Can you provide at least three customer references?

The easiest way to determine the amperage of your electrical outlets is to check the corresponding breaker in your home’s breaker panel. The number is likely noted on the circuit breaker. If that fails, it’s possible to tell 15-amp and 20-amp outlets apart by looking at them. Fifteen-amp outlets have two vertical holes, while 20-amp outlets have one vertical hole and one T-shaped hole. 

Typically, refrigerators should not be plugged into GFCI outlets. This is another appliance with a motor that can be prone to a little current leakage. Using a standard outlet saves nuisance tripping and the potential of waking up to a refrigerator full of warm food. The only exception is when the refrigerator is in a garage, where all outlets must be GFCI.

That depends on your setup. If a circuit breaker already has GFCI protection, then everything connected to that specific circuit is being monitored. You don’t need additional GFCI outlets on that breaker.

However, if the breaker is not GFCI, then you should have GFCI receptacles for at-risk outlets nearby water sources, because they are not receiving protection. Breakers in a breaker box can vary between GFCI and non-GFCI. Look for GFCI labels on the breaker or try to find the breaker model number to look it up if you aren’t sure.
