Quite a while ago......
Trouble call, 'funny smell' in a retail store
Had a thru-wall ac unit; put my hand on the EMT...it was hot (temp). Shut off AC; removed male cap, opened the 4" sq.
One conductor on the brass terminal of the recept; silver term had a short piece of #12 to a sht metal screw that also secured the box.
Guy said...it works fine, but occasionally it shuts down. Checked the EMT, ss conn were loose and had arc marks all over.
I went to the panel and cut the 120 feed (30 amp cb) Replaced the whole thing!
