DC wires in AC box.

Featured Replies

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

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...
