Polaris Connectors

[Karl H]

Does anyone know if the black insulated Polaris connectors
can be used in a concrete hand hole? I see they are UV rated,but what about
a hand hole? The UV rating is telling me it's ok,cause anything UV rated
would also be exposed to a damp/wet environment. Just trying to clarify.

Those are direct burial.

 

[Karl H]

sorry, "submersible." A concrete hand hole isn't direct burial but
yes, could be submersible.

I just read 314.30 (C). Thank you for pointing me in the right direction
Chris.

Karl, here is a typical hand hole install with Polaris Blue.

I just talked to 4 supply houses and no one carries Polaris "Blue"
They all said,"Why not Split bolts?" My reply was, "How is a split-bolt
submersible?"

Is your install likely to be under water ?

Even in San Diego a hand hole will eventually get some water in it.

It wouldn't matter if the install never got wet, its still a wet location.

And if you want to dispute a handhole being an 'underground installation'...
