January 22, 20251 yr I know the reg says AC and DC may not be mixed. Can I route from a DC db through an AC db and then into trunking. The DC wires will be inside a conduit/Sprague pipe. The DC and AC db's are directly next to each other. Thank you Edited January 22, 20251 yr by Herbie.
January 22, 20251 yr That is one of the vagueries of the regs: ... ... So - DBs must comply with the requirements of wireways. D.C. and A.C. may not be in the same wireway. BUT! that requirement is not in clause 5 (it is in clause 1), so a decent lawyer could probably argue that it does not apply. So, it will come down to the interpretation of whoever does the CoC. Personally, I would say it is OK, as long as the DC wiring is in a conduit with an insulation rating greater than the highest AC or DC voltage. But I am not an electrician, or a lawyer...
January 22, 20251 yr Author Thanks Justin. I'v looked at hundreds of installation pics and 99.9% the batt cables and inverter PV in comes out the same trunking.
January 22, 20251 yr Both are DC? But that is also (usually) illegal, as all insulation must be rated at the highest voltage in a wireway, and battery cable is often only rated at 100V...
