Hello
Have a code/how to do it question for everyone here. When wiring a DC disconnect for solar do you have to bring the negatives into the box even though they do not connect to anything or just the positives? The 4 ga wire I will be connecting is the combined wired (from 3 solar panel strings on breakers) coming from a midnight solar MNPV3 combiner to the DC disconnect, from the DC disconnect to a midnight solar epanel which has the PV + buss bar.
Thanks in advance
