I didn't find any instructions for a "bond screw when used" on the label and didn't find a strap or bar. Maybe I'm just tired but I've studied it over and over and I just don't see where it's bonded to the enclosure - does anyone here?

It's too blurry to tell but when I've seen that type of strap bonding the bus bars together (at the bottom) I've always found the green bonding screw a couple of holes down from the top of one bus bar or the other. Of course, sometimes there's just the hole with no screw in it.

That kind of Siemens panel would have used copper bonding straps that secured to either the left or right side of the panel, where the arrows are in the picture. This one is clearly not bonded.

Is that a 4 wire feed? If so it should not be bonded.

If it is a 4 wire feeder there look to be neutrals on the left bus along with the jumper between the buses.

Looks like a typical 3-wire feed with an electrode grounding conductor going downward.
