Relocating and Splicing an Underground Electrical Circuit

How to move and splice an underground electrical circuit

Moving and Splicing an Underground Circuit

Question: I have an outdoor hot tub that needs to be moved about ten feet. However, a deck that has since been built over a portion of the buried line, for ease, I would like to dig up the line ( in conduit) that is accessible and splice the wire at that point. I would then attach a junction box at the deck and then re-dig the trench to the new location. Is this an acceptable solution ? or does the wire need to be in one piece for the entire length ? Also , If the junction box is acceptable,how high off the ground does it need to be ? The deck is only 14 inches high.

Any help is greatly appreciated!

Thanks Bob

Thanks for your electrical question Bob
Relocating and Splicing an Underground Circuit
Bob, the conduit can be dug up and relocated, and the circuit may be spliced. The location for the junction box will determine the type of junction box that will be used and the method of the circuit wire splice that will be acceptable. The key is that the junction box must be accessible, weather it is in the ground in an acceptable enclosure and using approved splice methods, or above ground, however if above ground then the enclosure should not be located within close proximity of the hot tub. If the enclosure is metallic then it must be grounded.
