This was in a small diner that used to be a service station, I was called to add a 20amp circuit for an ice machine that was tripping a overloaded circuit. I couldnt believe my eyes when I popped the cover off. If you look at that lone empty knockout to the right, thats where I installed my nice new MC cable. I tried to convince the owner to a changeout to no avail, he said "the whole place looks like this". I made a note of all the needed corrections on the invoice, snapped a few picts for reference, then told him never make a late insurance payment.....by the way, after installing the new circuit i got a amp reading of 20.3amps on the new dedicated circuit, told him time for a new compressor......
