110.14 & Table 310.16

[mcjacobsend]

I am asking this question for testing reasons and not real life. My understanding has always been 100 amps or less use the 60 degree column unless all terminals are marked 75 degrees, and over 100 amps use the 75 degree column. I have been recently told it does not apply to motors, is this true? I am taking my Mn Journeyman A test for the second and I hope the last time. If you could Please lend a hand in this. If you can think of any other things that are simple that would trick me up for a test please let me know.

Thanks

Todd

I will yield to Tom Bakers's knowledge in an earlier thread he stated:

NEMA assumes motor conductors and terminations are made from the 75 deg c column.

Got a link to that thread?

Thanks Gus, a little disappointing though, I was expecting to see a link or text from a NEMA bulletin.
