Parallel 350's are feeding a 700A disconnect for a stamping press. What is the rule for feeder length inside the cabinet and entry location with respect to disconnect? Sections 312.8 and 409.104, (also 409.30 and 504.30), don't mention this. Thanks

I don't think there is a limit.

That said I make a real effort to enter the enclosure close to the lugs so in the future service techs will not need to move around live conductors even with the disconnect open.
