[Shop-talk] Square D QO breaker Box

[Jack Brooks]

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 bar, the two breaker connections are independent, without a common bar between 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 down or stud terminal which would be easy. I can run a 6 or 8 AWG from the inverter 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 this 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 covered all that well by ABYC either. I'd just like to be as close to NEC as possible.

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

Thanks in advance,

Jack
