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

Posted for < jeff@eurocars4less.com>: 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 jeff --
