What do you guys think?
Does a resistive (electric heaters) load bank require a disconnecting means near or at the load bank?
What about an inductive load bank?
What if the disconnecting means is three floors up and 200 yards away?
I started to look at this issue and came to the conclusion the the NEC does not require one. But I wonder if some other code might. Or if I interpreted the code sections wrong.
Article 470 does not apply since the resistors and reactors are component parts of another apparatus, and in any case does not seem to require a disconnecting means at all.
Articles 424, 426, and 427 don't apply.
It's not covered under NFPA79.
Could a fuse block be used as a disconencting means?
Just curious what you all think.
