I think the use of AC/MC is only one issue here amid probably a half dozen other violations that are just as bad. Obvious DIY/hacker job that all needs to be torn out.Is that really MC?
I can see the time clock is a pvc / plastic enclosure
How is the clock grounded? Provisions in time clock for grounding? Bonding bushings?
Is the AC / MC even grounded in the bell boxes?
