Good Afternoon Everyone,
I am having a friendly debate with an electrical counterpart regarding what the conductors on the attached are defined as. What we have is a 1/4" x 4" continuous copper bar around the perimeter of the substation room and from that copper bar we have 4/0 conductors to the associated substations. I am trying to keep my question as vague as I can, so as not to influence anyone's answer.
Your assistance is appreciated.
