Subpanel Ground/Neutral bars


My uncle put in a subpanel and him and brother argued about having a separate ground and neutral bar.
Is it supposed to be bonded to the panel or something?
I have some pics that Im not allowed to post until Ive made 5 posts.

The additional bar was just put into the can, so I assume they are both bonded

The sub-panel requires to be fed by four conductors, Hot, Hot, Neutral, Ground. The neutral and ground must be separated in the sub panel, and the the panel itself needs to be bonded to the grounding conductor.

That makes more sense.
We only have the 3 wires feeding the subpanel.
Does it actually need ground and neutral separated?
The panel came with only the one bar

What wiring method did you use to feed the panel?

Yes, it actually DOES need the ground and neutral separated.

If you look at the panel label, they will list all the accessories available for your panel, one item will be a ground bar.

its #6awg to the panel from the main panel
I guess we will have to run another wire from the bar to the main panel.

But did you use a metallic raceway? If so, that counts as the 4th conductor.

No, its just 3 wire romex
Is that how the bar is supposed to be installed, or is there a bonding screw that needs to be reomoved?

Does the 4th wire connect at the same place at the main panel as my other ground wire?

Looks like you have grounds on the neutral bar.
Did you use romex, type nm-b cable?
Is the panel in an attached or detached location from the main panel?
You have to replace the cable feeding the panel with 4 wire.
You can't use the bare wire in the 3 wire cable for anything but ground.
Can you take a pic of the cable inside the box?
