How many amps can a GFCI handle?

The number of amps that a GFCI switch can handle depends on the type of GFCI you are working with. Most GFCIs are either 20-amp or 15-amp, and can handle up to that specified amount.

Choosing Between a 15- or 20-Amp GFCI

When considering the amp level to feed a GFCI (Ground Fault Circuit Switch) in your home, consider the feed areas. Where will the GFCI be located, and what type of appliances will it be used for? 20 amps are needed for the most powerful appliances in the kitchen (toaster ovens, mixers, etc.), whereas 15 amps might be okay in your bathroom for smaller appliances (hair electronics, etc.).
