What do floor guys in your area do to get power to run their sanders? Its pretty frightening what I have come across here. I have seen extension cords with alligator clips directly to busbars or cords wired directly to a DP60 Amp breaker. The one I saw today, I am hoping I can get a pic of tommorrow. It had a piece of 6/3 romex going to a 4 11/16 box with two 3 wire range blocks coming out of that, it also had a 30 amp twist lock pigtail, and a hand box with a duplex recptacle. I was to scared to see what he had going on in the panel. I had a conversation with the GC, so I am hoping I will not see it tommorrow......yikes
