Electrical questions, answered by experts

Type S or T fuses don’t require any special removal or installation tools. However, replacing a cartridge-style fuse is easier and safer when using a fuse-puller tool. All of these tools should be available anywhere you can buy fuses.

The process of hiring a reliable electrician begins by searching for local professionals and verifying that they hold a master electrician certification and the proper licensing for your area. After that, you should read through reviews from past customers to see the kind of service you can expect from the contractor, as well as look at the Better Business Bureau’s (BBB) website to check for a history of company complaints. You can also ask for customer references to make sure you’re choosing a reputable professional.

Homeowners should avoid replacing a circuit breaker without turning it off. While you technically can replace a circuit breaker without turning off the main breaker—and professionals can and do—it’s only safe for electricians to use this process. Working with a live panel is extremely dangerous if you don’t have experience working with electricity. Always follow safety measures to avoid electrical shock.

Yes, the majority of appliances that run at 240v will work with a 220v outlet, but will often run slower and may have a slight delay in turning on. This could also cause long term damage to the appliance being used, so it’s recommended to always use the correct voltage for your appliance and upgrade to a 240v outlet if needed.

There are a few signs of a faulty or failing dimmer switch. This includes your dimmer overheating or feeling warm to the touch, buzzing or clicking noises coming from the dimmer, your dimmer failing to properly dim the lights, and flickering lights. That said, these signs could signal other electrical issues. You’ll need a pro to figure out if your dimmer is the source.
