[Shop-talk] Square D QO breaker Box

[Jack Brooks]

All,

From a Sprinter forum I learned have two good choices.


  1.  I can use a heavy cable between the two breaker lugs, strip a portion of the wire in the center of the run and use a Split Bolt Bonding Connector https://www.amazon.com/gp/product/B009OMIN7C/ref=ox_sc_act_title_1?smid=A1GAF1H4JQJZXC&psc=1 to join the incoming lead to the other cable where I would have stripped a section of  the center of the cable.  This uninsulated split bolt would need to be taped, etc., to protect it.



  1.  Alternatively, I can use an insulated Multi-Cable Connector, like this one. https://www.amazon.com/gp/product/B005GDFXC6/ref=ox_sc_act_title_2?smid=ATVPDKIKX0DER&psc=1
Wago connectors are available for smaller circuits. They are simple click on/off connectors, but only go down to 10 AWG.


I’m still debating which one to pick, but I like both of these options.

Thanks everyone for your help and suggestions.

Jack

I'd reach out to Square D and see their recommendation for 120v options. There may be a bus bar jumper designed to connect the bars. They may even recommend a better panel.

 I'm under the impression that you can't connect multiple wires in a breaker lug. Even had a home inspector write up two wires on the same breaker as a violation.

Mark,



Yes, that screw down connection is sized for 2/0, so I can squeeze two wires in one side of the circuit and run one over to the other side.  This seemed logical, but I just wanted to be sure that it was a reasonable solution.



Thank you,



Jack

It is designed to be fed by 240V (2 phase 120) power.  If you are feeding it with a single leg of 120V just tie the two main lugs together and run that from your power source.  The lugs should be large enough to have your incoming power go into one and then have a second wire in that lug feed the other lug.

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.
