I'm running 1 1/2" underground gray colored rigid nonmetallic conduit to
supply a subpanel for a workshop. My question is do I use pvc glue like you
would for pvc piping to join the sections ???
Do I use the glue in the bell sections as well where I would need couplings
I use a grey pvc cement. It is basically the same chemical
solvent soup as pvc cement for plumbing fittings, but instead of being
transparent is an opaque grey, supposedly from dissolved solids - bits
of grey pvc plastic.
Why do I use this instead of plumbing pvc glue? Because the
electrical inspector told me to.
Glue everything and let it sit overnight unless you want leaks.
Also: XHHW cable is better than THHN or THHW for service
in the damp environ that is underground conduit. Unless you
seal the above-ground entrances to the conduit moisture will
condense out of the air that diffuses into the cooler underground
