What did you use to splice the conductors?

Ilsco USPA-500SS-DB

It's a water tight direct burial splice. [Linked Image]

I see the green hand hole box in the picture, what size is it?

Don't really know, I believe the guys said something about 37" at the bottom.

It was homeowner supplied.

Is there a backup generator for this house - was it running if yes?

Yes about a 50 KW natural gas Genet, installed beautifully in the basement of the house. The exhaust runs underground about 100' from the house.

We brought are own power anyway.
