Tie Bar
 

Dave,
The tie bar is good for 428 Amps...ha ha. Yes, I used a wide piece, however that does not add anymore height than a skinny one - but you are right, that is what makes it tight. I would love to see your pictures of it mounted - had considered some spacers or improvement of mounting it rather than just using the side panel as a "gasket".

Planning on a thin Lexan lining for it - installed on aircraft side of the panel. Especially for skin side and top (prevent FOD from dropping down into back of panel is paramount for me).
Thanks for the help!
Jeff

I will take some pictures for you. The 3tc-2 breakers will make a big difference.
The jumpers can be at the far end of the bus. That way it won't be so busy up where the alternator leads attach.

Sorry for the late response on the polycarbonate breaker box lining. These are the pieces I had cut from my paper template. These make a nice insulation of the area.
