Electrical Equipment Tagging

[Chan]

Mike/ All,
Are there any standards that call for the tagging of electrical equipment...I am familiar with instrumentation being assigned an instrument tag, with a stainless steel id affixed to the transmitter, valve body or other type of instrument is this as per a particular standard, and if you know the standard and also are there similar standard requirements for IDs for electrical equipment, lights, pumps etc?

Thanks looking forward to your reply

I moved this to the NEC forum. The question is more general than hazarous locations.

I don't know of any standards. The only places I've seen "everything" tagged is power plants... and no two power companies I know of use the exact same convention. I believe engineering created the companies' conventions.

Take a look at this article in NFPA 70, it talks about identifying the disconnecting means. However, there are exceptions. OSHA in the USA also requires the same. I find it a good practice to identify every electrical enclosure for what it is and what are it sources. Both the major supply and if control power comes from another source.
