a electrican wants to wirenut 14 wireconductor to a nunber 12 conductor in order to wire a15 amp device in the same enclosure.his explanation is that a 20 amp plug on the end of the cord would not fit in the 15 amp device.an the most current would be 15 amps which the device could handle . in the event of a short the braker would trip weather it was a 15 2o or even a 30 amp breaker. you see this all the time with lites padle fans etc a16 or 18 wire on a 15 0r 20amp circuit. give code article if it can be done or not be done. this question may have been posted before on the site

What size CB is actually being used here?
If it's a 15A CB, no issues whatsoever.....if it's a 20A CB ~ then you have a problem: 240.4(D)

This is not covered by the NEC ~ MFG's spec.
 
The entire branch circuit would require an OCPD of 15 amps if any portion of the branch circuit feeding the receptacles were wired with #14 conductors. Appliances and fixtures have different rules.
 
Under normal circumstances, I'd guess his 15 amp "device" might be a duplex and one could then plug (2) 15 amp cords in.
The "paddle fans, etc" woild be covered under "fixtur wire" where this is allowed,

Your post is a little hard to follow but if you're saying that 14 AWG is going to be ran on a 20 Amp breaker then it isn't allowed.

However, despite the fact I'll get beat up for this, the reality is, a short (you know a few inches, hell, even a few feet) of 14 AWG can easily handle 20 amps. There are two reasons. One is that a peice of conductor that's rather short doesn't start heating up anywhere near as fast as a longer conductor of the same size.

That's the one that's gonna bother everybody.

The other point is that 14 AWG is actually rated for 20 amps. Don't worry, they wont like that either. :smile:

Either way, I'm not condoning this as a practice, just annunciating a couple facts.
