Hi!
I've heard before that mounting screws are not an accepted grounding for a self grounding outlet and a grounding clip should be used, I assume the code probably says the same (I'm in NJ, USA for that matter).
I'm curious why the screws are not an acceptable ground path, is it because they are too "weak" ground conductor for high load or because they are unreliable ground conductor as they can move or something like that?
If they're considered as a too "weak" ground, then why mounting screws are an accepted self ground for light switches though?
