Is this the lighting junction?

[bobdobalina]

The intermatic junction box broke. I want to fix it. I was thinking the job would be straightforward (and it still is, I guess) but:
1) does this appear to be a junction box for the pool light?
2) what's the blue wire? It goes in the first conduit and the third conduit but it's unbroken. I assume I can cut and tie it together when I fix but what is it?

It looks like my pool light junction box except mine (20+ years old) has a brass base. The jacketed cable looks like it's from the pool light. Do a web search for: pool light junction box code

The code requires the box to be at least 4" above grade & 8" above the maximum water line. Looks like yours was partially buried.

The blue wire probably goes to another light or something else on the same GFCI protected circuit. You can't mix both GFCI protected and unprotected wires in the same conduit.
