Greetings,
We are looking at repairing a few underwater splices on 40 hp. fountains. The splices are currently done inside a piece of 3" PVC pipe with an epoxy potting compound, with the insulated wires removed from the cable covering and exposed to the water. There is some electrical tape covering some of the insulated wiring, but most of it has unwrapped and fallen off. I'm looking for input on the correct splicing method, as the customer's engineer and our engineer do not agree on what is acceptable. The cables are 2 gauge and unfortunately undersized for 62 amps and a 1000'+ cable run. The wire size is causing an issue, as normally a quick disconnect would be used. I would appreciate any input on the correct method of splicing a 1 gauge or bigger wire underwater. The relevant information is:
480v three phase, 62 FLA. 4 conductor cable on a 1000' run. This will be spliced to an 8 gauge wire (on the fountain motor)
I have some great photos with the diver and the splices, but I can't figure out how to insert them.
Yours,
