How it Works
Underground electric line wiring provides power around your
property. It may provide electrical supply to sheds, outhouses, wells, swimming
pools, landscape lighting and more. Higher voltage applications may require a
conduit to protect the underground wiring.
Most underground electrical wire installations fall under
the National Electrical Code as well as local state and building codes. These
codes may specify or require any of the following:
- Type and size of wiring
- Type and size of conduit
- Ground Fault Circuit Interrupter (GFCI) system
- Burying depth
- Professional installation
- Professional inspection prior to use

located before any digging projects and call 811 for the “Call Before You Dig”
hotline to mark out any previously installed wiring. Wiring that is not rated
for underground use can fail and damage the circuit if water penetrates the
