Hello,

I am trying to install a 50 amp 6-50R outlet using a 50 amp breaker and 6/3 AWG wire.

The wire is 6/3 and has 3 #6 wires and an associated ground. The outlet is a 6-50R, there is a one wire connector cap to cap off the (unused currently) white wire (using black, red, and ground to the outlet). No internal wire clamps.

Wondering if a single gang deep box (20 cubic inches) is enough or if I need a larger box. I can't figure out how to count the 6-50R or even if it's legal to put it in a deep single gang box.

From what I have come up with so far

3 x #6 wire = 15 cu in
1 x ground = 1 cu in
2 x 2 6-50R = 4 cu in

The outlet counts double, is this correct?

Is this correct or am I way off? I ask because it says on this diagram that this outlet (not a 6-50R but it's cousin) won't fit in a single gang box.

You are correct that you are quite a bit off...

3x5=15 conductors
1x5=5 ground
4x5=20 device

40 in^3 minimum

OK...so...

I see the 3 x 5 ci for the 3 #6 AWG.
So you count the ground as 1, but times 5 for #6 AWG ground, makes sense.
Recep is normally counted as 2 x 5 (for AWG 6?) but is counted double because it's a larger recep?

Next thing, how close can my two outlets be? I would be running the 42 cubic in box on the left to attach to stud. Can I keep the single recep in the middle? I cannot find online any reference to min distance between outlets.

Thank you sir

This is for a welder, max of around 25 amps but didn't want to install a 30 amp breaker and wire on a 50 amp plug in a home. You never know who will buy it in the future, plus it looks sketchy.

Right, but it says single gang box. Not single gang deep box. Wasn't sure if one was different than the other. I was reading it literally.
