Attached exhibit shows neutral going to each service disco. In each service disco their is bar in which neutral lands.
Questions:

1. Is the bar in picture two separate bars bonded together or one bar?

2. In attachment Can neutral conductor connect in the same bar as equipment grounding conductor or additional separate equipment grounding conductor bar needs to be provided?

Each of those are Service Disconnects so the EG may be attached or landed on the respective neutral bar. A separate EG bar may also be installed, attached directly to the can per instructions. Additional neutral conductors may land only on the original neutral bar. EGs may land on either.

I am going to have install in which in each respective service disco the neutral conductor is going to land on the same bar as equipment grounding conductor, isolated grounding conductor land on the same bar. Bar inside each service disco shown post #1.

Don’t follow when you say EG
Maybe landed on the respective neutral bar? Are there cases it cannot be done?

As Tom said, you're still in service equipment, so there is no separate equipment grounding system yet. The premises EGC system only begins when you leave the service equipment.

Everything attaches to the neutral itself. Even if you had a redundant EGC bar, installed the grounding electrodes are supposed to land on the neutral bus, not a separate grounding bus.

The incoming service conductors go into the trough.

Mounted outside bonded with #6 AWG to the trough enclosure install also has intersystem bonding terminal. Can intersystem bonding terminal be bonded to the trough enclosure?
