I'm guessing this is a code violation???

Most modern panels can accept up to three grounds of the same size per hole.

Thank you for the correction Speedy..

I guess I was thinking about different sized wires terminating under the same lug. It's been a while..

Could you explain this a little for me please?

Are you saying that I couldn't have three wires under one wire nut?

Are you saying that I couldn't have a wire come from outside the panel, be joined under a wirenut in that panel and then leave the panel going somewhere else?

Either of the two mentioned above would be code compliant if they did not take up more than 75% of the cross sectional area of the panel.

I thought that this was not permitted. The panel may not be used as a junction box, which is what you describe.

Old, dead panels are often used for this (an upgrade), but that's something different.

Old wives tells gets started and leads to so much confusion that it is a wonder how anyone knows what is allowed and what is not allowed.

Enclosures for switches or overcurrent devices shall not be used as junction boxes, auxiliary gutters, or raceways for conductors feeding through or tapping off to other switches or overcurrent devices, unless adequate space for this purpose is provided. The conductors shall not fill the wiring space at any cross section to more than 40 percent of the cross-sectional area of the space, and the conductors, splices, and taps shall not fill the wiring space at any cross section to more than 75 percent of the cross-sectional area of that space.

The key word in this statement is “unless”.
If the cross sectional area is not filled more than 75% then taps are allowed in the panel enclosure.

Does it look pretty? NO
Is it allowed? Yes

On a side note, the max of 75% fill is fuller than any panel any home inspector is ever likely to see in his or her lifetime. That's pretty cram-packed full. Electricians joke that the 75% gutter fill is as full as you can get a panel by smashing all the wires into the gutter with the butt of a hammer.
