Need to make a public comment, mostly in my company, but need to know, are we supposed to use MCM or kcmil.
Is there a reason to NOT use KCM? What article will/does cover this?
Personally, I have always preferred to use MCM. But this would be incorrect. There is no code article for this, however the NEC "Style Manual" covers this. It says very clearly that the proper term for thousand circular mils = kcmil.
I hope this helps.
The NEC Style manual is free, and available in pdf format, online. We refer to it when we have to write code.
Just google it.
