Bonding conductor size at J-Box

... Would a #12 Ground Stinger not do its job on a 30 Amp circuit?

Probably....

But there's that fringe area of the #12 that wouldn't be there with a #10...

I wouldn't call anyone who would do that competent.hmy:

You wouldn't have to call them anything, since if you opened up a panelboard (not knowing that anything was changed) and seen #10'S connected to a 30 amp breaker you'd probably not think twice about it.

But I agree with the earlier post of it all depending on what the circuit is feeding downstream.
