Under the breaker? Make sure that it is not one of two that would be hot pass-through lugs.
A picture of the panel would help.
It's under the rows and attached to the case, I am sure it is grounded but I will ohm it out.
I would like to add a ground bar at some point but I lost the sticker to the panel so I do not know which bar works for the panel.
Buy a ground bar kit of the same make as the panel & it will fit.
