Tap Conductor

[Dennis Alwon]

I received this pm That I can barely read as I had cataract surgery today-- too tired...LOL I hope ypou all can help

Hello what part of the NEC does it reference tapping service entrance feeders to keep the load balanced for the multiple tenants in a retail shopping center.
What I received was a code violation for a recent shopping center where I show 3 sets of service entrance feeders from the utility transformer to a wire trough and for the Starbucks I showed 1 set of 600 KCMIL and it said I violated the code but no mention of the NEC article that you must tap all three sets to keep the load balanced for the remainder of the tenants. So this means that all the tenants I must use three sets of cable since the incoming service entrance feeders are 3 sets?

thank you,

Thomas

It sounds like the OP was trying to tap only 1 conductor of each phase instead of all 3 conductors making up each phase.

And the solution is not to run three sets of cables to each tenant but instead to common the three sets together with distribution blocks or Polaris connectors and then connect the one set of tenant wires at that common point. That keeps the three parallel sets identical for all practical purposes.

You can run one set to each tenant space but they must connect to all 3 sets from the utility.

Clarified it for you. (CIFY?)

thanks all for your responses, what part of the NEC covers the tapping service entrance feeders and balancing the loads?

There is nothing specific about service entrance feeders but there is a very general set of conditions for paralleling conductors which are subject to NEC rules. Whether they apply to particular service conductors depends on which side of the service point they are on.
