Have 2 Leviton subpanels on new build today. I’ve been researching the Leviton panels. I know that the neutrals are supposed to be connected next to the breakers and not the standard bus bar according to the legend and their website. My question is, how exactly does this work? Is there a connection back to the neutral line that I’m not seeing? Here is their website https://www.leviton.com/en/products/llphn One of the panels had neutrals for double pole breakers at the regular spot and the other was all 15 and 20 amp and were next to the breakers
Also, secondary question, this main panel outside has a jumper between the two neutral/ground bus bars that goes right over the hot bus bar. Typically I see them insulated where they cross or offset slightly above or below. Is this ok? The picture with blue circle.
There are a few white wires on the neutral bus bar above. That panel had Oven, range, Heat pumps and back up heat on it. No single pole breakers in that panel.
If your speaking of the B panel (last picture) they are called “plug on neutrals.” The plug on portion is for smart breakers, gfci, or afci or some combination of both. 120v circuits still need a “load” neutral to the device being powered.
The best way for you to understand this setup is to get the manufacturers part number and look it up on their website. Your pictures don’t show any concerns.
It does not matter where a neutral conductor lands on the bus as long as the breaker does not require a load side neutral. For example an oven that is 120/240 and does not need afci or gfi protection can have the neutral conductor land on the top, bottom or anywhere in between.
