You might be right, but n+1 grounds on a lug has not been recommended by the company because it has been tested and found deficient, which is why they didn't ask UL to approve it. | |

I don't see there is code available which talk about limitation on no. of ground wire on one lug in main panel ?wire on lug in this case ? | |

But I don't see only one ground on any lug. minimum is 2 ground on one lug. so you are saying 4 is too many on a single lug, how about 3 ? | |
