Neutral bar wires

[RESI]

I have run into a situation where I have run out of places to land neutral wires on a neutral bar. Can I install two neutral wires under one screw? The panel is a generaor sub-panel so there is no ground bus. Thanks to all who reply.

No.

408.41 Grounded Conductor Terminations. Each grounded
conductor shall terminate within the panelboard in an individual
terminal that is not also used for another conductor.

Why? .

If the neutral bar rated for double wire connection then you can, or you can install a grounding bar and move all of the equipment grouding conductors (egc) to this new grounding bar to make room in the neutral bar,

This is incorrect, as posted in post #2 408.41 prohibits more then one neutral conductor under a screw, there is no listed neutral terminal for more then one wire for branch circuits.

Second, if this is a generator "sub" panel there should not be any EGC's on the neutral bar to start with, you can not have a rebonded neutral after the main disconnect.

This is true for many lugs but it is not true for the neutral bar.

Mike Whitt, post #3- All of the ground wires stay in the main panel. The only ground connection in the sub panel is the one from the main panel to the sub panel box and onto the generator.

I think wanted to make sure you had the panel grounded, which you do but not with a ground bus jus a lug or something similar. You could add another neutral bar- they make them.

I would do exactly as Dennis sugest and just instal another isolated neutral bar kit,tie the 2 together and be done with it.

Just curious.

Just curious.

How would you size the jumper? Largest conductor landed or full size?
