 I have used MS25226 buss bars to connect breakers. They're plated copper and predrilled- I don't have a sample to check hole spacing but the Klixon breakers I checked had #8 screws. Aircraft Spruce carries them, also Chief Aircraft. One or both ends can be bent upwards and a brass screw soldered to the bus for a connecting lug. If you buy them long they can be cut up as needed.
 
 I like solder. My preference would be to solder the connector tabs in the picture to the buses to ensure full contact and to eliminate oxidation between the pieces. Rosin based paste flux makes that easy to do.
 
 The solid jumpers seem like a hard way to do things- my guess is the tabs would have to be soldered in place. They form an inflexible link between components- ambient and current induced expansion and contraction would put some stress on the connections. Putting a kink into the jumpers as you do with hydraulic lines would help but I'd be inclined to use stranded wire with crimped connecters, perhaps with a drop of solder on them. I'd also try to have the bus feeds connected at the center of the bus or near the highest rated breaker. With untinned copper connections I like to use a drop of DeOxit from Caig Laboratories. It wicks into the connection to ensure good electrical contact and to resist future oxidation.  -Bill Wade

Circuit Breaker Panel
Has anyone used the method described on Aeroconnections web site (Photo's and
Figures / Breaker / Breaker Panel Busing) to connect rows of breakers?
Can't find any documentation on the photos. Was inquiring to see if anyone
has used this method and can supply any info. on materials used or hardware
used pertaining to the application. I messed up slightly designing my panel
and realized the circuit breakers were a little tight. This method seemed like
a good fix vs other methods. Thoughts and Ideas welcome
thanks
