Bummer, what is the obstruction?Well, I tried to fit the CB inside the battery rack, and it's a no go. ?
Can't envision what you are suggesting.So, maybe from the CB (outside the battery rack), to the busbars of the battery rack.
I see... you rack is full.6 - EG4-LL Batteries 48V 100AH

That will work just keep the breakers as close to the busbar as possible.This:

Thanks for the detailed explanation. Looks great!Yes & No, copper bars are 6" long x 1" wide x 1/4" thick, but I have 2 pieces stacked.
Top pieces are drilled and tapped 3/8-16 & 5/16-18, while bottom pieces are drilled 25/64" & 21/64" which are clearance holes for the 3/8"-16 and 5/16"-18 bolts. This insures that upon torqueing nuts threads don't pull from copper. If I remember correctly 3/8" bolts are 1-1/4" long, and 5/16" bolts are 1" long.
Isolators bolts are a 6mm dia. x 1mm thread pitch.
I have 2 battery racks with 3 LifePower4 EG4 batteries in each. Batteries are 48v @ 100Ah.
Both battery rack output cables are #2 AWG with 5/16 lugs that feed these bus bar boxes which sit on top of racks. Then from bus bar boxes to inverter breaker with 4/0 cable with 3/8" lugs.
Ampacities of copper bus bar alloy UNS C11000 is 620 amp for 1/2" x 1".
