How do you terminate direct burial wire?
Answer for USA, Canada and countries running a 60 Hz supply service.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.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

In the United States, the National Electric Code dictates the depth of buried electrical lines. You have not provided enough info for me to give an accurate answer. For instance, some cables are manufactured for direct burial, that is to say without a conduit. Other considerations would be whether or not you are crossing a driveway, or alleyway. However, the maximum depth required is 24 inches to the top of the conduit or cable. Under certain conditions this depth may be reduced to 18 inches to the top of the conduit. Thank you for your desire to make a good installation.

What is rigid conduit and where is rigid used?
There are two types of rigid conduit systems. One is PVC rigid conduit. It is mostly used in underground installations and in in areas that contain water or corrosive chemicals. The second type of rigid conduit is steel conduit. In Canada it is mostly phased out due to the high installation labour costs. Small installations are still used in small explosion proof areas.Both types of systems in Canada have been replaced with Tech armoured cable. Installation costs are lower and the wire is in the cable set, so no wires to pull. It is approved for above grade and underground direct burial installations. Tech also has been approved in explosion proof areas when used with the proper explosion proof end connectors to seal the cable.
