Help - Adding a third outlet off of 1 outlet, shallow box so no pigtailing


Thanks Jim but what about using the push pins in the outlet like the guy at the hardware store suggested?

"Pass through" wiring is not proper wiring practice per the 2011 code.

"pass through" is when you just cut the insulation off the wire and wrap it around the screw and keep going with the wire. Commonly found with ground wires.

What you might want to try is to replace the box with a 2 gang box, and blank the one side out to use as a junction area for wirenuts and pigtails. This is what I would personally do.

Then just get something like a Pass and Seymour TP-138 (color) wall plate to cover it!
I think it's a bit of a stretch to say that the push in connections will "burn your house down". Receptacles are UL listed for this. Is it a great connection method? No. But a properly installed receptacle would not "burn your house down" should the connection come off.

While the backstabs on the devices are listed by UL for use with #14 wire, many feel that they are not as reliable as a screw terminal connection.

Good point about AWG for backstabs. They are limited to #14 AWG and I personally hate them... The OP may be able to use a device with a backwire clamp, though. I've seen some of the newer Cooper and Leviton devices that allow two 12/14 AWG solid wires to be clamped under a single screw, which could potentially eliminate the need for pigtailing. They cost slightly more, but do allow two wires under a single clamp and are not restricted to #14 AWG. They also provide a much more secure connection than a traditional backstab.

DO NOT use those push ins.

I dont care if the engineer has 3 doctorate degrees.

Those connections become loose with repeated use. Im referring to the ones on residential outlets that are spring loaded, not the commercial pressure plate/screw down rear wire.

They WILL become worn, they WILL ARC and they will eventually cause an issue, HOPEFULLY just a dead outlet, but they are known to cause fires. Most if not all of the reputable electricians in my area REFUSE to use them. Some larger new home electricians (I know of one) took a hit on labor when he told his guys to only use the screw terminal.

Also, you cant feed through from the rear push in sites.

Commercial grade switches and receptacles have this design.

@ Detroit, I was a professional firefighter for 5 years, I have experienced poor electrical work and seen what it does. Trust me, outlets get used and worn out. Push in connections will become loose. Copper degrades with repeated excessive heat. When you bend the wire (push in then shove in the box) you create a hot spot. Just trust me, spend the extra time using the screws and learning good wiring practice.
