Service questions
Questions about trenching & underground electrical
Yes. Jeff digs the trench with his own excavator, lays the conduit, runs the underground feed, and wires the building — one contractor from the trench to the first outlet.
Jeff digs it himself with his own excavator and Bobcat, then backfills and finishes the grade. That removes the wait on a separate excavation crew and keeps the whole job on one schedule.
Depths follow code for the wiring method used. Jeff lays it out to code for the city or county, tells you what's required, and handles the inspection.
Yes. For a pole or stand-alone feed, Jeff handles the pole base and the underground run together — the same hands that dug the trench set the pole and wire it.
