Re: PVC to RMC - Bonding?
Are there any allowances for sleeving the pvc conduit in cast iron or ductile iron pipe (DIP) as far as burial depth is concerned? In other words, can you put the pvc conduit through a section of DIP and have 6" of cover without grounding the DIP. Seems to me a solution, but I don't see anything in the NEC about this. Interesting thread. Thanks.
