Hey Guys,
I am designing a solar system, and I wanted to get an opinion in the number of wires in an RMC. The design is as follows:
6 sets: [4 #400 MCM AL-XHHW2
1 #3/0 CU SSBJ
4" RMC]
According to NFPA 70 Annex C: I can put 9 #400 conductors in a 4" RMC
So is it recommended to use 3 RMC with 9 conductors in each along with the ground or use 1 conduit for each set?
Thanks
