- PV system DC circuits that exceed 30VDC run inside a building shall be contained in a metal raceway. 690.31 D
- OMG! Seriously? I've yet to see an online video where the entirety of the PV DC circuit is encased in metal from the point of entry. Most installations are very similar to mine. I've used liquid-tight for everything and it all needs to be replaced with metal conduit...including my 1-1/2in Sched 80 entry and junction box. I've done my best to figure out an exemption for this, but I can't find one. I have to assume that others here have come across this. I still haven't figured out how / where to transition from PVC to MC. This is going to be quite a cluster indeed.
