This question relates to another thread:
What's the best way to splice 1/0 cable?
I have 1/0 cable in 2" conduit running in ground at a depth of 2 feet.
The job required a splice, which was accomplished by using Polaris connectors inside a sealed PVC Junction box.
I'm trying to seal the J-Box and cover my trench, but if I move the junction box to position it in the trench, the little rubber caps(denoted by red arrow) on the Polaris connectors keep falling off.
Does anyone who has experience with these connectors come up with a solution for keeping them on? Or is there another way I could keep moisture out of the connector?
I thought about a silicone caulk or possibly butyl rubber, but wasn't sure if this might have a corrosive effect on the aluminum set screws. Electrical tape would work short term, but what about after several years in the ground. Any ideas? I can't close my trench until I get this resolved.
