Re: Push in wire connectors
yes, have used the Wago type in prefabrication of outlet and switch assemblies in office environments, this is with #12 Awg. stranded and there can be problems with the stranding folding away from the "tension grip" mechanism and not having all the conductor strands engaged. Solid does not pose this problem. Of course they are U.L. listed but time will tell as to their durability.
