OH! Did I open another can of worms? Sorry! smile Actually the first thing I thought of is, why don't they allow you to "pin Back" #12 ga wire in a receptacle, but yet they will allow you to pin back #12 here?

As for splicing in a small raceway, maybe that would be good (allowed?) in a Plugmold strip. However you don't think that anyone would use it to splice in a piece of EMT do you?
