How deep do you need to put conduit in the ground?

Answer for USA, Canada and countries running a 60 Hz supply service.

There are a lot of different rules that apply to your question. Generally, when buried on residential property, conduit may be buried as little as 12 inches, measured from the TOP of the conduit to the SURFACE of the soil at its shallowest point.

When buried on commercial or industrial property the general rule is 18 inches, but that can vary depending on the voltage involved, what type conduit is used, and what the surface material is.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.
