Termination of direct burial wire is done as you would terminate any other set of wires. However, direct burial does not mean you can direct bury the terminations. The wire must be brought into a building by an approved method; or the wire must be brought into a box designed for burial, with the box accessible from the surface of the ground; or the wire must be brought into a piece of equipment that is partially buried and designed for that purpose.
In no case should the wire reach a depth of less than the minimum required depth for the installation without being protected by conduit. And in no case should the wire enter a building without conduit unless installing UF cable is allowed without conduit in the installation.

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.

It is a wire with special insulation that protects it under ground. On the wire there will be a stamp "UF" or underground feeder. That means that it can be buried directly in the earth.

Wire in conduit for underground feeders has to have an insulationrating for wet and damp locations. In the marketplace there is also wiring thathas an insulation rating for direct burial that does not need to be installed into conduit.
Crimp on wire ends are the most common.

For a 100 amp direct burial installation, it is recommended to use copper wire with a minimum size of 3/0 AWG (American Wire Gauge) or larger. Copper wire is preferred for its conductivity and durability in underground applications.
The conductor can be pulled into conduit and then buried but it is not certified for direct earth burial.

The recommended installation guidelines for 2-2-2-4 aluminum wire for direct burial applications include burying the wire at least 24 inches deep, using a protective conduit where the wire emerges from the ground, and ensuring proper grounding and bonding according to local electrical codes.

When using 2-2-2-4 direct burial wire outdoors, it is recommended to bury it at least 24 inches deep and use a conduit for added protection. Make sure to follow local building codes and regulations for proper installation.
No, it is not possible to run Romex wire directly underground in a basement. Romex wire is not rated for direct burial underground and should not be used in this application. Instead, you should use UF-B (underground feeder) cable or conduit with appropriate wiring for underground installations.
Sorry no, you need to look for "Direct burial/Outdoor" in the description.
The current rating of 350 MCM aluminum wire for direct burial will depend on the specific environment and installation conditions. It is recommended to consult the National Electrical Code (NEC) or a qualified electrician for precise calculations and to ensure safety and code compliance.
For outdoor electrical installations, it is recommended to use a type of wire called UF-B (Underground Feeder) for a 14/2 gauge wire. This type of wire is designed to withstand outdoor conditions and is suitable for direct burial in the ground.
