Underground Tee Splice

I have a lamp post between my house and barn that is powered by a wire that is tee spliced into the run. I found it wrapped in tape and covered in tar when it failed years ago and tried a home brew repair that has not worked. From some research I think I understand that wire should not be an underground splice. The wire should run into a junction box above ground and then continue to the barn from the box. Is that correct? If so the fix would be an underground splice kit with a wire to the box and a wire out from the box with an underground splice kit to the wire continuing to the barn. Since the wire is in place I cannot lengthen it to reach the box.

Look up "Scotch underground splices." I've used the epoxy potted ones many times. Stay away from the shrink wrap type.

Twenty years ago I was subbed out to an excavation company that was installing a new water line directly thru intersections and across companies front lawns. They cut and I spliced. All my splices are still good after all that time. I think I used at least thirty five to forty kits.

Underground splices are allowed by the code.

Any underground slice should be an approved kit.
