double checking my sub panel wiring

I'm running power to a 100 amp subpanel at an outbuilding on my property. The outdoor box has a 100 amp main and 20 spaces. My question is there is both the neutral bar and the ground bar are isolated from the box and the bonding strap is not connected. But there is a strap running between the ground bar and the neutral bar. Should this be disconnected? It is a 4 wire system. Here is a pic if I can get it to upload....

Most panels require an additional ground bar purchased separately. The label should have a diagram to show where they mount.

Those are both neutral bars. An additional bar needs to be added for ground like pcboss mentioned.

I think that panel lets you remove the insulated bar then use the right one as ground and the left as neutral - look at the label/instructions.

What's up with a Square-D breaker in a brand new Eaton panel?

Good catch, the Square D breaker isn't listed for use in a Cutler-Hammer panel.

The panel also looks to be outside so the NM is an issue.
