Bonded to panel or not?

I’m trying to determine if this main electrical panel bus bar is bonded to the enclosure. I run into this problem from time to time. Is there any certain thing to look for when trying to determine if it’s bonded other than a bond screw?

Thanks, Paul

Do you have a picture of the panel’s schematic? it will usually show you the location where it gets bonded.


It did not have one on the panel, But I might be able to look it up. Thanks

Kinda difficult to tell in the pic, but IMO, this kinda infers that it is… whether intended or not!
