Regarding NFPA70e and similar - please push me to a different forum (topic) if there's a better place...thanks in advance for any insight...
Just using a generic example, say 50kV - NFPA70e says 8' to exposed circuit parts.
What if my "exposed circuit part" is inside of a fence? Is it still "exposed?" Considerations about fence height, gap size, and material come to mind - but if a "fence" isn't good enough to say "it's no longer exposed" - then why is a transformer case good enough? And so on...
Bottom line - we're trying to protect a prototype / test area with a fence. Safety people insist on putting it at the approach boundary - which means a minimum room size of 16 foot square, plus test (usable) area. A normal "barricade" - say, a rope-line or tensa - is not meant to prevent access - and is not capable of preventing access - so 8' still makes sense. Not so, with a tall tight fence.
So - does my test area need to be 8' from the INSIDE of my fence? Any reference in NFPA (or other) where I can at least have the conversation?
