Installing and Repairing Underground Electrical Wiring
Electrical Question: Years ago I buried an insulated electrical wire in the back yard of a lake house and attached an outlet on one end and a plug on the other.
- Length of Wire
The distance is about 75 yards.
- Tripped Circuit Breaker
Now when I plug it in by the house to a GFI outlet, even with nothing plugged in on the other end, the breaker trips.
- Buried Wire Connection
I put a new plug on the end, is it possible the wires are crossed?

Common Problems when Installing Underground Wiring and How to Fix Them
- Buried Electrical Wiring
This question prompted me to have some of my own questions
- What kind of wire did you use?
- How deep did you bury it?
- Buried Electric Wire Type
Direct burial cable Type UF, Underground Feeder, is the most commonly used cable for this purpose as long as it is sized correctly.
- The UF cable should be buried 24 inches deep.
- Where the cable emerges up from the ground it should must be protected with PVC conduit.
- Junction Box and Cover
Outside wiring should be placed in a weather proof junction box with an approved cover.
- Damaged Buried Wire
If you did not use this method of wiring then any one of the above mentioned components has possibly been damaged and the circuit may need to be replace using the correct wiring methods.
- Wiring Worked Before
If the wiring you installed long ago did work at one time, then the wiring is most likely not crossed up if the connections are still made the same.
