Equipment electrical enclosures
(OP)
Just received a large tool to install that has a large area open for ventilation. I would be fine with that except a 6" wide by 36" tall part of that area leads into the electrical controls at 480V. Are there requirements for electrical cabinets to be enclosed, finger safe, and of sufficient construction to be able to contain an arc blast up to the rated fault current.






RE: Equipment electrical enclosures
As for being arc-blast resistant, that is almost certainly not a standards requirement unless specified at time of purchase.
If you can provide more info on the equipment and relevant standards, there's probably someone here who can provide more details than I can.

JLS - the manufacturer used a heavy gage piece of sheetmetal with a few bends to form the electrical backplane. It is enclosed on all but one side and that side is a 6x30" rectagular opening. To me it is like have a circuit breaker enclosure with a dead front panel and one open side mounted to a unistrut rack.
