How do you find a short in a underground wire?
Cheapest and easiest: Put a load (e.g., incandescent light bulb) on the short circuit (A to neutral). Then follow the cable with a non-contact AC current detector. The detector will stop beeping where the (first) short circuit is, since that is where the current is able to loop back in the cable.
Can you splice underground electrical wire?
Splices are required in underground cable for a variety of reasons. They are required if digging equipment accidently hits a wire, or if the wire connection fails during the original installation. Regardless of why a splice is needed, the repair process is the same, and uses something called a splice kit.
Can I bury a junction box in the ground?

How do you bury outdoor electrical wire?
Underground Wiring Requirements – How Deep Do I Bury the Wire? Use direct-burial underground feeder cable at 24-inches deep (or more). You don’t need to use conduit at this depth with UF cable, however, you do need to provide PVC conduit on your vertical feeds starting at 18-inches.
How deep should outdoor electrical wire be buried?
