In addition, National Codes dictate the depth, below ground, these lines must be buried. Some low voltage underground circuits could be as shallow as 18 inches, while most higher voltage circuits will be deeper than 24 inches.
Thereof, How far down are electrical lines buried?
18 to 24 inches
Also to know is, How much does it cost to move power lines underground? According to PG&E estimates, it costs approximately $3 million per mile to convert underground electric distribution lines from overhead. PG&E’s cost to build new overhead lines is approximately $150 per foot or $800,000 per mile.
Subsequently, question is, How deep are electrical wires in the ground? At 18 inches, you can use THWN-2 conductors inside a continuous length of PVC conduit, which protects the wire all the way through the trench to the house. At 24 inches you can bury underground feeder cable, using PVC conduit to 18 inches below ground only where the wire comes up.
