Turning 1 outlet into 4
Hi all. I have an outlet box for the sump in the basement with a single circle electrical outlet. I want to take that and turn into a 4 outlet box. The junction box is a 4 outlet size already, so I should just need to but a couple outlets. Is there a diy wiring guide for this. I'm sure its pretty simple, but a diagram would be great. Btw, this is the end of the line, no other boxes connect from this box.

assuming you've read the disclaimer

And that you know how to safely disable power (heck just go ahead and kill the main to be safe...)

Gut the old box, you should have just one bundle of wires, with a black/white/bare ground wire.

Run the black to the darker brass screw on the outlet. There should be an identical screw right below that one, take a small piece of wire and go from there, to the 2nd outlets' brass screw.

Do the same for the white,

and then the same for the bare ground screw.

you have a 4-gang box with one single receptacle in it? typically when a single receptacle is used it means that its a dedicated circuit and the single is used so you cant plug anything else into it besides what the circuit is dedicated to but since its in a 4-gang i dont think it was a proffesional installation. make sure the existing outlet is gfi protected since its in the basement. then you could just daisy chain the hots(black) from gold screw to gold screw and the neutrals(white) from silver screw to silver and the ground(bare) from green to green and so on. or you could pigtail the existing wires into 4 wires with a wire nut, (pig tail the blacks into 4 and the nuetrals into 4 and the same for the ground) and connect each color to the screws like above. i cant say ive ever seen a quadruple duplex cover plate but im sure you can find them somewhere.

Sorry for the confusion..I have a double gang box with a single outlet in the center. Theres one outlet instead of the four you would normally have in a double gang box. And yes, I'm sure it was just meant to power the sump and nothing else, but theres no other boxes in that area. So I could either tap off of that box and make a totally new box, do an entirely new run of the power panel, or do what I plan on doing, just replace the singe outlet with 4.

Thanks for the help guys! I'll post a pic when I get done, I'm sure I'm just confusing you guys due to my lack of knowledge of the lingo.

The box is 4" x 4"? (2 gang size) If you do this, you will have to get a 2 gang plaster ring to adapt the box. GFCI protection if this is an unfinished portion of the basement. Either 2 GFCI recepticles, or 1 GFCI and a duplex from the load terminals of the GFCI.

Am I correct in assuming you want 2 duplex outlets?

if it is a single recepticle, it's probably like that for a reason...meaning check the amp draw of the sump pump before doing this, the first thing you plug into the duplex may trip the breaker when the pump is running.
