[RE-wrenches] Push-in Wire Connectors

[Glenn Burt]

Kent,

 

Can you direct me to a code citation that says that splices made inside a
NEMA 4 rated enclosure must be suitable for the location of the enclosure,
and not the protection level afforded by the enclosure?



I have had this discussion and lean toward the other side that splices made
in the enclosure need only be rated to the protection rating of the
enclosure, as long as all conduits are properly terminated with fittings
that meet the minimum rating of the enclosure.

 

Thanks,

 

Glenn Burt

Jason,

The roof is a wet location so connectors rated for wet locations are
required. The NEMA 4 rating of the junction box doesn't change matters.

Anyone see a problem using Ideal In-Sure Push-In Wire Connectors in a NEMA 4
roof mounted PVC junction box? Specifically, Ideal Model 39 for splicing #10
AWG.

 

They are 105C, 600V rated, but not rated for wet locations. I've had
inspectors require wet location rated twist-on wire connectors before in
these boxes. I foresee an issue.

 

Unfortunately, these connectors were not addressed in John Wiles code corner
Making Connections article in 2003. May be time for an update!
