3" PVC 480 volt circuit

[jb1934]

Circuit is run four feet below grade and operates a tower crane. Plumbing subcontractor while excavating his gas line broke a two inch square piece off of the 3" conduit. What acceptable form of repair is there other than replacing a section of 3" pipe?

Thanks

Check with Carlon, they make split duct that goes around the conduit in two sections. I don't know if it UL listed. Also there are repair couplings available that slide over the OD of the pipe. for the first the conductors can stay in the conduit, for the second they have to be removed. This is all assuming the conductors were not damaged.

The cables were checked and no damage was done

Thanks Tom
