Snapped this pic this morning where I buy gas. Tough to see in the pic but this old recep and intercom speaker have been repeatedly painted over. Raceway is EMT with a set screw connector.
No; with 15 or more coats it probably meets a Section 500.7(J) Protection Technique. Just kidding.
What makes you think it would need to be explosionproof? See Figure 514.3; it appears to be out of the classified location. Section 514.7 is also relevant, but it looks OK.
Well, it just shows that painters are the same everywhere. I don't know how many times I have gone out to survey an installation only to find every nameplate, vent and gauge painted.
