Hi,
Nice post. I am agree with you that The most colorful equipment is electrical bus duct and bus plugs. We’ve seen a thousand manufacturing plants over the years and many, especially the older ones, have painted their old electrical bus duct and bus plugs specific colors to identify the specific electrical system or the specific load being fed.Thanks for sharing all the useful information with me.

@Bryan We do not know of OSHA specific text that says plugging a bus plug into a live bus duct is live work or not live work. We would be surprised if OSHA would be that specific. We do know that OSHA CFR 29, Part 1910.309 through 1910.330 mandates “Safety–Related Work Practices” … “be employed to prevent electrical shock or other injuries resulting from either direct or indirect electrical contacts, when work is performed near or on equipment or circuits which are or may be energized.” The danger of shock or arc blast hazards must be reduced to a safe level such that the person would not be seriously injured or killed… as per OSHA’s General Duty Clause. MIDWEST believes removing and installing a bus plug on an energized bus duct, even if it is classified as not “Hot Work,” is not safe. MIDWEST recommends de-energizing the bus. Because of the actual physical work required to remove or install a bus plug in a live bus duct, there is an extreme arc burn hazard.
