Help me out a little here please, with this double tapped neutral thing.
I see double tapped neutrals, and grounds a lot.
So I understand why double tapped hots are bad, because you can have two branch circuits on a single breaker which can be two many amps. But this doesn’t apply to grounds and neutrals.
Is double tapping grounds and neutrals bad only because more than one wire doesn’t fit under the screw? And if so, some ground/neutral bars have big screws and little screws, are the big screws made to allow for double tapping?
