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.
Can you bury wire without conduit?
Direct Burial rated wire is approved to be run in the earth in accordance with the National Electric Code (NEC), usually without the use of conduit to surround it. The combination of the insulation material and its thickness keeps out moisture and other harsh factors to protect the wires inside.
Can Romex be buried without conduit?
Romex cannot be used in the situation you describe as buried conduit is considered a wet location. You must use conductors such as THWN. Also, minimum burial depth for conduit (PVC I assume) is 18″, unless you run rigid or IMC, in which case you can go a minimum of 6″.
What kind of electrical wire can be buried underground without conduit?
Direct burial wire is a type of outdoor electrical wire that is buried underground, usually without conduit. Naturally, these cables have to possess distinct characteristics to withstand the environment of the ground.
How deep is power line to my house?
Some low voltage underground circuits could be as shallow as 18 inches, while most higher voltage circuits will be deeper than 24 inches. If there are underground electrical circuits on your property, pay attention to where they are located.
How far can you run 12 2 wire underground?
You can run 50′ on a 12 gauge wire. I can’t imagine why you would want to run a number 12 any further than 50′. If you have to go that far you are better to have 30–50+ amp with 2 phases’ and a sub panel with breakers. This way you can run multiple things.
Can I use underground wire inside?
The most common types of direct burial cable used in residential projects are underground service entrance (USE) and underground feeder (UF). While standard NM cable is rated only for dry, interior applications, UF cable can be used outdoors as well as indoors.

How far can you run 12 gauge wire on a 30 amp circuit?
Yes, based on the National Electric Code or NEC, you can use 12-2 AWG cables for THHN or THWN-rated wires. These cables are made for general purposes and can hold up to 194 degrees without taking any damage. It simply means these wires can withstand the heat temperature drawn by a 30 amp circuit breaker.
How many outlets can you run on a 12 2 wire?
For general use receptacles, In commercial buildings it is limited to 180VA per duplex or single receptacle, therefore on a 12/2 Romex cable not otherwise subject to ampacity derating and protected by a 20 amp circuit breaker, that would allow a maximum of 13 receptacles.
