An outlet on the outside of the house provided a source for power, so we dug a ditch from that location to where we would build the shed. Check your local codes, but the basic requirements are (1) adequate gauge wire and breaker, (2) GFCI protection on the circuit, and (3) special underground wire or conduit.

Do electrical wires need to be in conduit?

In a household wiring system, most of the circuit wiring is in the form of insulated cable that is run inside wall, floor and ceiling structures without conduit. Conduit typically is used only where circuit wires are exposed (or surface-mounted or buried) and therefore need protection from damage or moisture.

Does outdoor Romex have to be in conduit?

It's rather common to protect or shield Romex with PVC in locations where (wet or not) it might be harmed by objects or people, but if you're going to be running high voltage (120 V+) outdoor lighting or receptacles it's a much better idea to just use UF, or PVC conduit and pull the THHN conductors through it as you ...

Can you bury Romex without conduit?

According to the National Electric Code, regular romex wire must be housed in conduit if run outdoors. However, UF rated wire can be run without conduit.

Can electrical wires be exposed?

However, your electrical wires can become dangerous over time if you don't take necessary safety precautions. Live wires transmit electrical current which, when exposed, can even cause electric shocks or fires.

What kind of electrical wire can be buried underground without conduit?

Can Romex wire get wet?

In most homes, ROMEX® wire is used for electricity, where the copper ground wire is wrapped in paper and then, in turn, wrapped in the live and neutral wires. If this wiring is exposed either through a break in the plastic coating or even at the socket, the moisture can be soaked up by the paper, creating rust.

Can Romex wire be exposed in a garage?

Exposed NM, NMC and NMS cable are allowed to be run in “one- and two-family dwellings, their attached or detached garages, and their storage buildings” by the National Electrical Code (NEC 334.10 and 334.15).

Can you run electrical wire above ground?

You can run electrical wire outside to nearly any location. Although some types of electrical cable do not have to be enclosed in conduit for outside installation, enclosing any exposed cable is a good idea.

Bonding the steel siding is not required, but you can if you'd like.

What is code for buried electrical wires?

Low-voltage (no more than 30 volts) wiring must be buried at least 6 inches deep. Buried wiring runs that transition from underground to above ground must be protected in conduit from the required cover depth or 18 inches to its termination point above ground, or at least 8 feet above grade.
