Subpanel question

Am I missing something because I don't see where the neutral bars are bonded?

Possibly it's a subpanel. There should be a first disconnect where the neutral is bonded.

They are bonded from below. You can see part of the cross bar between the hot bus bars at the top just below the main breaker.

Joed is correct. The neutral bars are bonded with a bar that goes behind the hot bus bars.

The larger neutral wire should not be connected to the ground bar to the upper left.

Also, it appears that somebody forgot the bushing on the main feeder pipe.

When asking about the neutral bars being bonded I think of the bonding to ground, not that the two neutral bars are interconnected.
I believe that large white wire is being used to bond the neutral bar to ground. Unless I'm not seeing where that wire goes correctly.
The need of bushing on the pvc fitting is debatable.

That "white" wire connecting to the left hand ground bar is the ground wrap from the 60A 240v circuit in the bottom right. It should have been left bare or taped green.

Yes, that white appears to be the extension of the ground for the 60A circuit. My question is, is this a subpanel since it has a 4 wire feed with the neutral bond being ahead of this panel at a separate disconnect? Otherwise if this panel is the first disconnect I'm not seeing the neutral bond.
The OP needs to clarify the question about the neutral bar bonding. Whether between the two bars or to the panel.

Yes it is a sub panel and the white wire is the ground from the range which has since been taped green.

I was wondering if the two bars were bonded because I couldn't see and knew they should be.

But you said this was a subpanel. In a subpanel the neutral bus never gets bonded to the grounded panel box. The neutrals must be completely isolated from ground.

The neutral bars should be bonded I know it should be separated from ground

You are misusing the term bonded. In electrical, bonded refers to being connected to ground. As to the two neutral bars, they are interconnected but not bonded to ground.

From the NEC book Art.100 Definitions:

Bonded (Bonding) Connected to establish electrical continuity and conductivity.

The two neutral bars can be bonded together, and not necessarily bonded to ground.

If this is a sub-panel where is the main disconnect?
