Perhaps the person who put this here was used to European standards or something? I don’t know. But I challenge anyone wishing to remove this to actually do their research before they just remove it just because some idiot used to be at this IP address who did some stupid things.

OSHA has a threshold at 50 V. The NEC has a lot of rules for 1000 V and less. And then there are limited energy systems but the rules for those are not just about voltage and even in those I don’t see 100 V threshold. IEEE calls low voltage anything under 1000 V, medium voltage anything over 1000 V and high voltage starting at 35 or 50 KV. Don’t know where this idea came from undo Tags: Reverted section blanking Visual edit Mobile edit Mobile web edit
