Electrical System FAQs

AFI. GFCI. Circuit breaker. Fuse Box. What does it all mean? Electrical jargon can get confusing at times especially for homeowners that have never been in the industry. All of the technical terms and processes can leave people with tons of questions so we’ve put together some of the most frequently asked ones for you:

What’s the difference between a breaker panel and a fuse box?

Both devices are designed to turn off, or trip, any time there is an electrical overload. The major difference is that breakers are mechanical and can be reset whereas fuses must be replaced. You can find fuses in older homes, but many new homes use circuit breakers because they are more efficient and offer greater protection.

What is a GFCI?

A GFCI, or ground fault circuit interrupter, is a type of outlet used whenever there is a chance it may come in contact with water. This device will shut off power to a circuit when it detects that current is flowing along an unintended path.

Why are my lights flickering?

Flickering lights could be an indication that there is loose wiring or a voltage fluctuation. Both of these reasons are extremely dangerous and need to be tended to right away. Be sure to call in an expert electrician with years of experience to take a look.

What is an AFCI?

Similar to a GFCI an AFCI, or arc fault circuit interrupter, breaks the circuit when it detects a dangerous electrical arc. This is to prevent electrical fires or other electrical hazards that may occur.
