I have used MS25226 buss bars to con= nect=20 breakers. They're plated copper and predrilled- I don't have a sample = to=20 check hole spacing but the Klixon breakers I checked had #8 screws.=20 Aircraft Spruce carries them, also Chief Aircraft. One or both ends can be = bent=20 upwards and a brass screw soldered to the bus for a connecting lug. If you = buy=20 them long they can be cut up as needed.

I like solder. My preference wo= uld be to=20 solder the connector tabs in the picture to the buses to ensure full= =20 contact and to eliminate oxidation between the pieces. Rosin based pas= te=20 flux makes that easy to do.

The solid jumpers seem like a hard w= ay to do=20 things- my guess is the tabs would have to be soldered in place. They = form=20 an inflexible link between components- ambient and current induced=20 expansion and contraction would put some stress on the connections. Pu= tting=20 a kink into the jumpers as you do with hydraulic lines would help but = I'd=20 be inclined to use stranded wire with crimped connecters, perhaps with a dr= op of=20 solder on them. I'd also try to have the bus feeds connected at the center = of=20 the bus or near the highest rated breaker. With untinned copper=20 connections I like to use a drop of DeOxit from Caig Laboratories. It = wicks=20 into the connection to ensure good electrical contact and to resist fu= ture=20 oxidation. -Bill Wade
