I installed some outdoor post lamps. I am located in the Northeast and
used PVC conduit and outdoor wires. At each lamp post, I used a
junction box and spliced wires to power each lamp (I know, mistake,
should have brought the wire all the way into the lamp and spliced
there). Anyway, water is somehow getting into the junction boxes over
the winter. During the summer, even with heavy rain storms, I do not
have any problems.
At the beginning of each summer, I have the to try and "blow out" the
PVC conduits to dry the connections. Its tiime consuming and I have to
dismantle the lamps to accomplish this.

Is there a better way to splice these connections with something other
than wire nuts? Is there a way to make water tight connections?

Thank You.

Jack

They make wirenuts that are made for underground. Once installed, the
entire wirenut (and splice) are sealed in a water-proof substance.


You should find them in Lowe's or Home Depot Electric department.

King one step is a gel filled wirenut for that purpose. Ideal also makes
them. I believe HD has the Ideal nut

problem is whether its condensation or are junctions filling with water

Try these electrical splice kits. I've seen them at electrical supply
shops:
