[RE-wrenches] Push-in Wire Connectors

[Jason Szumlanski]

Rats! I thought that would be the case. What approved, cost effective
and secure splice methods are others using to splice Enphase trunk
cables to THWN-2? I'm not a fan of wet location twist-on connectors.
Some of the mechanical splices out there are very expensive.

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!
