I am building a Sprinter van into an RV and have a question about the 120v =
breaker box (SquareD QO24L70RBCP).  It is a 2-Space, 4-Circuit load center.=
  My concern is that while the Neutral bar has four positions on a common b=
ar, the two breaker connections are independent, without a common bar betwe=
en the two.  This surprised the heck out of me. My inverter (Victron 24/70/=
3000)  has a single AC output with a "cage clamp" terminal, not a screw dow=
n or stud terminal which would be easy. I can run a 6 or 8 AWG from the inv=
erter to the Breaker box, but it needs to go to the two separate screw down=
 terminals.  Physically, I believe I can run an 8 AWG wire into one breaker=
, and then back out to the other breaker, but I'm concerned about whether t=
his is a code violation.

Any thoughts on how I can run wiring to each of the two breakers safely and=
 within code?  Yes, mobile is not really covered by NEC, but it's not cover=
ed all that well by ABYC either. I'd just like to be as close to NEC as pos=
sible.

Last resort - is anyone familiar with a small breaker box with standard bus=
bars for the breakers to snap into?

Thanks in advance,

Jack
