20a recpt & #4

[Alwayslearningelec]

Can you terminate #4 or #6 THHN on the terminals of a 20a receptacle? THanks.

#10 is the largest you can use. You would have to splice to a smaller gauge.

Thought so...thanks.

What are you working on? Voltage drop?

I can't wait to see a pic of a receptacle back-stabbed with #4

Be an interesting box fill calculation too.

YUP. I know sometimes at the panel they will put a terminal block and run smaller wires to the panel....but i dont know about at the receptacle. Thanks.

No kidding - it would require minimum 6" boxes, based on a set of 4's coming in and a set of 4's leaving!

Horsegoer, is this a hypothetical or is it relevant?

See #6, it is a project that he is working on/out. Why does it matter?

Am I blind? I'm not seeing that. :?

my bad. i am mistaken.:ashamed1:

We have had to run 4 AWG for 20 amp receptacle circuits, no big deal, make a splice on each end to 10 AWG.

Relevant. I had some 20a site receptacles that said to use #6 due to VD.

Is that all you do?

 

[jumper]

That's it. no biggy.

I'm not seeing how you would comply with 314.28.

ETA: of course, I'm not seeing how to size a box with a single entry in it, either...?

Good catch. #4 does present a problem. Mostly I have done pole lights and used this application.

Use a 4 11/16" box, 1" conduit, and feign ignorance.....:angel:
