[QUOTE="binky, post: 520392, member: 490"] Having given those regs a read, if the steel flex conduit is earthed, it would suggest it would comply. But, as the DC cabling has no fuse protection as such, it wouldn't do a lot. Inverters do have DC monitoring built in, but that would not stop the solar panels pumping energy to the fault location. I once had a plumber core drill through the DC cabling, it eventually stopped shorting out about 6 inches above the short, when the ends of the cable had burnt out in a way that prevented it from arcing out anymore.
