Lab tests are great but I would like to see a test of some of this MC, shoved in a snap in fitting with the ground cut off and installed in a beach house for 10 years. (or pretty much anywhere with 90% humidity most of the time). If we can't keep a wire under a binding screw from oxidizing to the point it fails, how can this "intimate contact" last very long?
I really worry when the piece of MC is pretty short, like a whip to a big motor, and that "intimate contact" is only hitting 20 wraps or so. I guess it really doesn't take that much to operate the O/C device but that does tend to fly in the face of 250.122
