Power taps
Power taps
(OP)
I'm designing a conveyor system. On this system I have 11 sub-enclosures and one main enclosure. The power for the systeme is 208VAC, 3 phase, 4 wire, 60 Hz, 60 amps. Also there's 4" X 4" (hoffman) wireway (layin type) that connects all the enclosures together. The question that I have, is it legel to tap (split lug) off the 208VAC, and have that tap in the wireway.

What specifics do you require?
RE: Power taps
RE: Power taps
Main feed conductor is 40 ft. long, the main fuse is a type J 60 Amp fuse, and voltage to be used is 208VAC, 3 Phase, 4 wire.
I hope this is enough information.

A # 12 conductor and a 20 amp cb or fused disconnect.

Each sub-enclosure has it's own disconnect switch and primary fusing. The primary fuse for each sub-enclosure is between 15 to 10 amps.

It may be better to provide the normal power distribution with properly protected branches.
Also, to be on the safe side, the 1/3 may be increased, however, then it is better to look into an engineering trade-off, namely, which solution is better.
