Hi Scott and the regulars here.
I have a question that I hope that you guys can help me answer.
I have done these sorts of calcs a million times before, but owing to lack of practice in the last few years, I've forgotten how on earth they're done.
OK, here we go:
A given 3 phase Star-connected installation, has the following Phase currents:
  • R Phase= 30A
  • Y Phase= 25A
  • B Phase= 40A

Having this information, how then is the current likely to be carried by the Neutral calculated?.
Thanks in advance,
