Receptacle and wiring question


I have two questions.

1. I went to buy some receptacles. The receptacles said 15 AMP, but I am putting them on a 20 AMP circuit (12-2 wire). I was talking to the sales guy and he said they were rated for 20 AMP pass through and they would be fine on a 20 AMP circuit as long as they weren't the only thing on the circuit. Is this correct?


2. When wiring outlets in a room, what is the best method..pigtail?

Thanks!!

One or more 15 amp duplex receptacles on a 20 amp circuit is code compliant. Pigtailing is more reliable and makes future trouble shooting easier.

Go for backwire outlets (Not backstab outlets). Easy to install. You slide the stripped end of the wire under a clamp and tighen it down with the screw.

Don't confuse this with backstab outlets, where you just stick the end of the wire in a hole and it "locks" it into place. Those come out over time.

Yup 15a duplex (2 places for plugs) is OK on a 20a
I've bought a few 20a outlets & GFCI's....price a few years ago was close

If the box is smaller & only 2 cables I will use the screws on the receptacle
All my new boxes are 3" deep & I usually pigtail
On MWBC I think pigtail is required on the Neutral now ?

Yes, pigtailing the neutral is required on a MWBC.

Thanks SD.

Price difference was a little over a dollar at Home Depot for regular outlets. I am going to have around 40, so this will save me a little money.


When you pig tail do you just wire nut the incoming and outgoing hots together and then run a pigtail to the hot side and the same with the neutral side? The screws are bonded so it doesn't matter which one I attach to, right?

What is MWBC? Is it multiwire branch?

You have the concept of pigtailing correct. Either top or bottom screw is acceptable.

MWBC = multi-wire branch circuit. Normally done using a 3 wire + ground cable. Both the black and red are hot legs fed from opposite legs in the panel. The neutral is shared between the black and red. Under the 08 NEC the breaker needs to be a 2 pole breaker and the wires need to be grouped to identify this as a MWBC in the panel.
