I understand the theory regarding normal size equipment grounding conductors when paralleling. For example, a 1200A service requires 4 sets of conduits, and the appropriate size EGC is #3/0, and a #3/0 is needed in EACH of the 4 conduits.
My question is this. Is there a maximum size conductor I can get to before I need to break that down even further??? For example, for argument's sake, let's say I need a #1500 KCMIL EGC for EACH conduit. Can I instead use two #750 KCMIL EGC for EACH conduit?
