We had the concrete deck around our community swimming pool ripped out
for replacement and find
the electrical line to the pool light badly corroded. There is a 1/2"
brass or heavy copper (red brass?) conduit extending
about 6" from the light housing in the pool wall to what was once a
junction box in the deck,
but the box is long gone. It looks like the guy that replaced the
light 10-15 years ago simply ripped
out the box, joined the conductors, and poured concrete over it. From
that point to the cabaña,
about 25-30 feet away, is a badly corroded metal conduit.
I've learned that "deck boxes" are no longer allowed, but pool lights
can now be purchased with
very long leads. So, we want to locate a new junction box at the
cabaña. The question is what
kind of conduit should be used from the end of the existing copper
conduit to the new junction box.
Can we somehow join the copper to the gray plastic conduit, or do we
have to use copper all the way?
