I've read Can I add a standard receptacle on a GFCI circuit and have a similar situation in that I need to add a receptacle to an existing GFCI circuit, but when I pulled the existing GFCI plug from the wall, it looks substantially different than the version described there.

What I have looks like this, with connections on both sides:

first side second side

I suspect they're chained to a receptacle at the second vanity in this bathroom, but unfortunately it's across the room from where I need the new outlet to be (which is right underneath this one). What's the correct way to make this happen, short of calling in an electrician?

You can use twist-on wire connectors (or other approved connector), to create a "pigtail".

  • Turn off the power.
  • Remove the LOAD side wires from the GFCI.
  • Using a twist-on wire connector, connect the white wire you removed from the GFCI with the white wire feeding your new receptacle and a short bit of the same size wire (6-8" should do).
  • Do the same with the black wires.
  • Attach the bare ground wire from the new cable, with all the other grounds in the box.
  • Connect the other ends of the short bit of wire to the appropriate screw terminals on the GFCI.
  • Reinstall the GFCI.
  • Turn on the power.
  • Worked like a champ, and nothing blew up or burned down. Thanks!
