[j rae]

do they make mc cable conductors in brown orange yellow conductors?? Is required by code for 277/480??

I'm pretty sure you can find mc in B,O,Y Gry. Only if more than 1 nominal voltage is supplied within the same building -- I don't believe the specific colors are required but it has been the general markings for 277/480 as long as I can remember. Orange is req for high leg in a 4 wire delta system 110.15.

Yes, been installing thousands of feet of it. :slaphead:

I'd rather be running pipe.

And if you have two different voltage high-leg delta systems in the same building, you have to find a way to distinguish the two orange conductors.
