In NFPA there are many places it lists 50v as the cut off point for voltages where we need all our special PPE to be worn. As far as the context, it seems to only be specific to AC voltages. Where is the point for DC voltages and where can I find it in print?
Thanks,
Jerry

It is the same, all voltages listed in the 70E are DC or AC RMS unless otherwise noted.

Thanks Zog, for some reason, I thought they were different.

Thats a common question, it is not clearly stated, I had to ask the 70E commitee myself.
