What kind of electrical wire can be buried underground?
The most common types of Direct Burial wire are USE, with a thermoset insulation, as well as Tracer Wire and UF.
Can you bury wire without conduit?
The cable can be installed directly into the ground without a conduit. As long as the cables are installed correctly, they will be able to operate under the ground for a long time.
Does underground wire have to be in conduit?

What size wire do I need for a 200 amp underground service?
The underground installation of a 200 Amp service should follow all codes and have the correct permit. For a 200 Amp service, you’ll need a 2/0 AWG for copper conductors, or a 4/0 AWG for aluminum or copper-clad aluminum.
What size underground wire do I need?
The total load of the devices on the circuit is what determines the size of the wires.
What size wire is rated for 100 amps?
A 2-gauge non-metallic sheathed electrical cable is the best way to connect the master and secondary panels. The cable needs to have at least one hot wire and one neutral wire. The size of the wire should be 2 gauge.
How do I determine electrical cable size?
14 to 2 are the two numbers separated by a hyphen that are used to classify an electrical cable. The conductor’s gauge and the number of conductors inside the cable are both shown by the first and second numbers. There are two 14-gauge conductors in 14 to 2.
