Quick Electrical Code Question...
(OP)
I have a 600V bus with a 200A rated plug on it. The 200A plug is fused at 150 A. We have changed the single wire lug connections on the plug to double wire connections to feed two machines from one bus plug. At the machine control cabinet it is fused at 60A (some have a 75A breaker instead).
The bus plug where the power feeds are split and the machines themselves, where the 60A protection is, are approx. 20 feet away from each other. Does this arrangement break any code requirements that anyone can think of?

Currently I have a 600V Westinghouse Bus Duct in a particular area of the plant. One 200A rated, 150A fused bus plug feeds two identical pieces of equipment. The majority of the equipment load is a 40hp motor in each machine. The protection at the machine is either a 60A time delay fuse or a 100A breaker (it varies by machine). Does this pairing of loads on one bus plug break any code requirements? I am in Ontario but if this is a problem, I would think it would be anywhere. Thanks.
