What conduit do I use for underground electrical?

THWN-2 wire, for example, is a standard type for running through underground conduit. Use thick-walled conduit at least 3/4 inch in diameter for this application. Never use thin-wall EMT conduit for underground applications. Running wire through Schedule 40 PVC conduit.

Can I use white PVC for electrical conduit?

“Grey” electrical raceway PVC pipe is UL (underwriters laboratory) listed as an approved electrical raceway; “white” plumbing PVC is NOT. This is because the “grey” electrical variety is UV resistant and “white” plumbing is not.

How deep should electrical conduit be buried?

18-inchesThe National Electric Code (NEC) sets the required burial depth of electric wire in rigid, non-metallic conduit, such as PVC, at 18-inches. Cable in any conduit, including PVC, that is buried at this depth is not in danger of being severed or disturbed by normal digging.
