Underground electrical conduit laid in a trench across a rural Tennessee yard

What's included

Underground Service Laterals
Buried service entrance routes from a pad-mount transformer or utility pole to a meter base, planned around the utility and property layout.
Detached Shop & Pole Barn Feeders
Feeder runs to detached shops, pole barns, garages, and guest spaces planned around load, distance, and how the building will be used.
Underground Conduit
Conduit selected for the route, physical protection, pull path, expansion needs, and the inspection requirements that apply.
Trenching & Backfill
Mini excavator and trencher work with bedding, marker tape, and backfill handled according to the site and applicable requirements.
Utility Coordination
We coordinate the meter disconnect, locate, and connection directly with your utility provider.
Permits & Inspection
Permits, inspections, and utility locates coordinated when they apply to the job and local requirements.

Buried electrical work is difficult to correct after the trench closes. Route, conduit, pull points, physical protection, grounding, utility coordination, and the intended use of the building need to be settled together before excavation.

Trent Electrical plans the underground route before digging starts. Conduit type and protection are selected for the location, the risers, the pull path, traffic exposure, and the inspection requirements that apply. Sweeps are planned so feeders pull cleanly, and marker tape or other identification is used where it makes future digging safer.

Detached shop and pole barn feeders are our most common underground job. Most rural properties in Hawkins County have at least one outbuilding that needs real power — a shop, barn, garage, equipment shed, or work area. We size the feeder, conduit, and subpanel around the load, the distance, the voltage drop, the available service capacity, and what the building is expected to do.

A useful outbuilding plan accounts for present equipment and realistic future changes. Distance, voltage drop, service capacity, panel space, and likely loads shape the feeder and subpanel before the route is opened.

Common reasons homeowners call

A detached garage, shop, barn, shed, or equipment building needs real power instead of extension cords.
An old overhead line to an outbuilding keeps taking storm damage or crosses a bad route.
A trench is being planned before concrete, driveway work, landscaping, or building construction.
The outbuilding needs a subpanel, lighting, receptacles, garage-door opener outlets, or dedicated tool circuits.
A future welder, compressor, freezer, heater, lift, or charger should be considered before the feeder is sized.

Which service fits?

Choose underground service when power needs to move between the home, meter area, and a detached structure or outdoor equipment location. If the work starts at the utility meter, review meter and service work. If the main panel lacks space or capacity, a panel upgrade may need to come first.

Homeowner questions

Can the whole shop or barn be wired after the feeder is installed?

Yes. The same project can include the feeder, subpanel, grounding and bonding, interior lights, exterior lights, receptacles, and dedicated tool or equipment circuits.

How is feeder size decided for an outbuilding?

The plan considers expected loads, distance, voltage drop, available service capacity, panel space, and what the building may realistically need later.

Should I dig the trench before calling?

It is better to talk first. The route, depth requirements, conduit path, utility locates, pull points, and inspection timing can all affect where and when digging should happen.

Can future equipment be planned before I buy it?

Yes. A future compressor, welder, freezer, heater, lift, or charger can change how the feeder and subpanel should be planned, even if the equipment is not installed yet.

Are permits and inspections needed for buried electrical work?

They often are, but the details depend on the property, utility, and scope. You’ll receive an explanation of what applies before the trench is opened.

How it works

Four steps. One licensed electrician.

01
Route + locate
Call before you dig, walk the route, and mark existing utilities.
02
Trench + conduit
Dig and place conduit for the approved route, with pull points and protection planned before backfill.
03
Pull + terminate
Conductors pulled clean, landed in the service or subpanel equipment, and verified before energizing.
04
Final documentation
Open-trench photos, inspection steps when required, and clear notes on the buried route.
