The missing cover can be easily corrected, but the rusty fitting in these runs of metal raceways, that show the affect of dampness and the possible heat from the piping systems used for that purpose leave me with a chill!

The code should call for a separate EGC in the form of a wire sized per Table 250.122 in cases like this one.

I applaud those who are in the design area when they make sure that this is done as a regular method.
