how deep does a power pole go
Best Answer: A 20 foot pole set in firm soil goes in 4 feet. A 40 foot pole, 5 1/2 feet get buried. A 50 footer in 6 1/2 feet. Tops out at 8 feet buried for an eighty foot tall pole. That's for firm soil. Rocky soil is a bit shallower. Talk to your power provider before doing any digging around power poles.
