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.

What is the current rating of 350 MCM al wire for direct burial?

You have 6 gauge underground wiring that has a rubber coating over it is this safe or should it be in side somthing else?
There are cables approved for direct burial. These will have markings on them like USE or URD. There is no way to answer your question without knowing the specific type of cable you have. If it is not approved for direct burial and you decide to put it inside an underground conduit there are still regulations that apply. Underground conduit is classified as a 'wet' location, so the wire still must have the rating for wet locations. Not all types of wire do. If you are concerned that you may not have the correct wire, have a qualified electrician look at it. Don't try to dig it up to look yourself, especially if it is live! If the wire is not approved for direct burial, it will eventually corrode and fail. Since it is underground, there is little likelyhood someone will be hurt, but you will certainly be left in the dark!
