GFCI outlets have two sets of terminals, line and load. Line is meant to take hot & neutral from the mains panel. For load, you can run wire from there to downstream regular outlets, and it will give them GFCI protection too. This is annoying when the outlets are in different rooms and it's not clear what's connected to what, but can save money when wiring up a bunch of outlets in a kitchen, for example, since a GFCI outlet can be $20 or more, while regular outlets usually only cost a couple bucks. |
