#14 Tails

[dm9289]

I recently worked with another Electrician doing trim outs and we were connecting plug to plug wiring on a 20amp circuit. He was using #14 for tails stating it was easier to work with and OK by code because #14 is actually capable of 20amp. 310.16 did back up the ampacity but had an asterisk next to it regarding circuit breaker size. So basically what I am asking is it OK to use #14 jumpers on a 20 amp ckt? Also is it Ok to use 15amp receptacles on a 20 amp ckt?

Thanks for your help with the references as always

Your friend is wrong about the tails. #12 if hooked to a 20 A breaker.

Drag him to 240.4(D)(3) &(4).

Ask where he thought the verbiage in 240.4(B)(1) was headed? Now about the other question-

Also is it Ok to use 15amp receptacles on a 20 amp ckt?

Yes.

Take a trip over to 210.21(B).

Also take a look at 210.19(A)(2).

Cool. Another electrical issue with no gray areas put to bed in 4 posts. Now if we just get the rest of the code this easy to handle....

Now we just need to figure out how to stretch this out to 100 posts. :grin:

Did he backstab those plugs? That should stir up something.

Ground up or down? Wrap with tape? :grin::grin::grin:

Match the rest of the place! And tape only if it's in a metal box. Just my opinion.

Here is an illustration that applies, note that210-19(d) ex 1(c) is now 210.19(A)(2).

And with that, let's close this thread.
