I don't mean to hijack this thread, but the title seemed suitable for a question I have.
Is it legal to use non-insulated crimp connectors (the spade/fork variety) to attach stranded wire to the ground screw of receptacles and switches? If so, I assume it is also okay to use the insulated type for side wired switches. These are 3M brand connectors, being crimped with the Klein red & black handled crimping tool. I don't think they make that particular tool anymore, but it is just like the Klein #1006
. I guess I should get rid of that tool and get the 1005 for both the insulated and non-insulated connectors. Thanks.
