feed 2 loads from transformers

feed 2 loads from transformers

feed 2 loads from transformers

(OP)
I am trying to tap an additional load from a particular transformer. My co-worker told me he has done that before and that should work but I just want to have more opinions.
This transformer currently feeds an MCCs (2 sets of 4-350kcmil). I want to tap its bushing to feed a panel that will feed motors (combination starters) and of course I will protect the panel with a breaker. This transformer has enough to feed both de MCC and the panel I will use.

My question is : can you feed 2 differents circuits from same transformer if there are bushing spares?

Thank you guys

RE: feed 2 loads from transformers

Probably depends on the applicable code rules.  With no idea where you are it's tough to tell.

RE: feed 2 loads from transformers

Yes, subject to meeting NEC tap rules 240.21 or 240.92 as applicable. I presume NEC applies to you, judging from the use of "kcmil".

As for more options, I always try not to saw seeds for a mess to grow. I would put a distribution board.

David, I'm located in Arizona.

Rbulsara, putting a distribution board is a good option. but we want to see if we could connect our load straight into the secondary of the transformer then connect it to a panel board for the new load.
This is mainly because it will cost us lots of money if we were to remove the actual wiring and connect it to a panel distribution...

RE: feed 2 loads from transformers

You may have protection issues if the main breaker in the MCC is part of the transformer protection scheme.
How will a fault or overload on your new feeders be cleared?
