I have a Junction box with incoming 120v coming into it. I want to Install a GFCI recpetacle in this location. From this same location I would like to splice the load side of the GFCI in order to protect planned receptacles which will be located to the left AND Right of this location. If I splice the load and carry load in 2 different directions, will this protect properly?

Yes. That's what pigtails are for. No problem at all.

  • Incoming (from panel) wires -> LINE side of GFCI
  • Outgoing wires - short pigtails (colors matching the outgoing wires, normally black & white) -> LOAD side of GFCI
  • On the other end of each pigtail, wire nut the two matching wires to the other locations.

All grounds (both sides) are connected together.

Yes, as long as you're connecting the wires at the load end, the GFCI doesn't care how it's connected.

You'll have to install a large enough box to accommodate 9 wires coming into it though.

According to this chart https://www.bhg.com/home-improvement/electrical/how-many-wires-in-an-electrical-box/ You're not going to be able to use a standard 3 x 2 box (even the 3 1/2 inch deep one), since your outlet counts as 2 wires, so you need a box that can accommodate 11 wires.

GFCIs themselves take up a lot of space, so be sure to size the box correctly, otherwise you'll never fit the number of wires in it safely.

    4 grounds together count as 1 wire. – Harper - Reinstate Monica Oct 16 '20 at 20:14
  • will the 4 inch square 21/8" deep box be big enough? I could either change the box out or put an extension ring on it if its not. – journey Oct 16 '20 at 20:41
  • @journey That sounds plenty big. – Steve Sether Oct 16 '20 at 22:34
