What kind of wire do I need to run underground?
Sarah Smith .
Thereof, what kind of electrical wire can be buried underground?
The National Electric Code (NEC) sets therequired burial depth of electric wire in rigid,non-metallic conduit, such as PVC, at 18-inches. Cable in anyconduit, including PVC, that is buried at this depth is notin danger of being severed or disturbed by normaldigging.
Beside above, does direct burial cable need conduit? However, if you only need a power supply (withoutwires to control lights from inside the house,) you can use adirect burial cable, placed in the soil withoutconduit. The NEC (National Electrical Code) requires that UFcable be placed in a trench at least 24 inchesdeep.
Simply so, how far can you run electrical wire underground?
At 24 inches you can bury undergroundfeeder cable, using PVC conduit to 18 in. below ground onlywhere the wire comes up. If you're consideringrunning a power lineunderground through your yard,you have four options. Your choice depends on how muchpower you want.
