Use of NEC Tap Rule
Use of NEC Tap Rule
(OP)
I have a situation where I have an existing 100 amp 3 phase service out of a panelboard. I would like to split the service in a junction box by terminating on a power distribution block and then feeding 3 individual 2 pole 30 amp receptacles mounted in the side of the jbox. There are #1AWG conductors coming in and I want to make the taps with #8AWG wire.
The receptacles are used to feed computer rack PDU's. The cord has no main breaker, but has 6 overload breakers(1 for 2 PDU receptacles) to protect the load side.
Is this a proper application of the NEC 240-21 10 foot tap rule?

Without knowing the voltage and is it delta or wye system. I would use interlocking switch fuse receptacle so that the load is switched off before removing the plug cap. Also is this computer a critical operations data system? If it is, see Art. 708, 700, and 645.
BTW the term you FEEDER, not service. Please, next post include all pertinent info.
Good luck!
