Hi, I'm Mike G and I'll be glad to assist you. Are you referring to main service or a sub panel?
Customer: replied 1 year ago.
Sub panel
Expert:  Mike G. replied 1 year ago.

No restriction on using it for a sub panel.

Customer: replied 1 year ago.
basically i can use any size breaker needed on a subpanel as long as its under what the panel is rated for correct?
Expert:  Mike G. replied 1 year ago.
Correct.

Hey whats up mike,
Im just switching out my old sub panel for the new slightly larger one. Dumb question but it doesnt make a difference which neutral bar i use does it?
Expert:  Mike G. replied 1 year ago.
Neutral bar is mounted on plastic, ground bar is in contact with the enclosure.
Expert:  Mike G. replied 1 year ago.

Don't use the green bonding screw on a sub panel.

Customer: replied 1 year ago.
Im aware of that, but if you look in the picture, theres a busbar on either side of the breaker slots. It doesnt matter which one of those two i use correct?
Customer: replied 1 year ago.
i know that too lol
Expert:  Mike G. replied 1 year ago.

Might want to use the one with a lug for the neutral, left side.

Customer: replied 1 year ago.
Thats what i was thinking. So the one on the right would just be for overflow?
Expert:  Mike G. replied 1 year ago.

Cable on left use left bar, cables on right use right bar. They are connected across the top.
