A similar thread was posted last week but this identifies the issue more clearly.
Reliance Controls makes manual residential generator transfer switches and sells them by the thousands.
On a 6 circuit 30a transfer switch and panel, Instructions tell the installer to route 6) 120v hot wires from 6) breakers in a panelboard out on 6) #12g red conductors to the transfer switch, and back to the panel on 6) #12g black. No circut neutrals to be run.
It is simply a 14' loop on the hot side of these 6 circuits with no neutral present.
The 2 conduits for the 6 circuits is 3/4 pvc, however those conductors do pass through ferrous metal when entering the transfer switch cabinet and the main panel. There are 6 conductors per conduit.
Nec 300.3(b) requires all conductors of the same circuit to be in the same wireway.
Even though when connected we observe no heating at this point, doesn't the setup as described, appear to violate the Nec?
