This is why we pull a ground wire in EMT down here if So. Florida. This conduit is in an semi-enclosed stairwell, as you can see they used some chemicals to clean the stairs and the salt content in the breeze has deteriorated the conduit and sprinkler riser in this stairwell. EMT is a listed for use as an equipment ground in 250.118, but we should still pull an equipment ground anyway. South Florida common sense.
I happen to take this picture yesterday in WPB.
Keep sending me those crazy electrical pictures.
Till next time be safe work safe
