ill keep the question short
75 kva 480 delta primary 120/208 wye secondary
primary protection 125 amp fuse. 3 #1 1#6 egc
secondary im taking the full 300 amps from the secondary 4#350 1# 2 egc
question is can i or can i not take the secondary conductors bring them into a wiring trough and tap them to 2 150 amp panels.
it is my understanding of the code that secondary conductors must be connected to a single over current device.
i know i can come out of transformer twice to the two panels.
i say taping the secondary conductors is taping a tap and that should not be done.
