So, I'm now not clear about this buss bar. Is this hot or a ground bar? If it's hot, I don't think I would want a hot bar exposed like this, particularly if it's not securely fixed in place. I would prefer to have some sort of insulating shield around anything hot otherwise it could easily be shorted to the airframe.

If its a ground buss, then its common with the rest of the airframe and shouldn't be an issue. I would also agree that Luca's idea of a small piece of tygon or nylon tubing will help prevent chafing. I would prefer the tygon so that you could tighten down the adel clamp and keep the wires from moving. The nylon would be too rigid and you are unlikely to be able to squeeze it enough to grab the wires.

my two cents

Default Thanks for the info

Sorry for the late replay, I was flying a trip to Osaka, Japan. The clamp is on the main bus bar the bar with shrink tube ties the two rows on the main bus. The bars are all made from .032 x .5" brass (the tie is .063)

I posted this on the Aeroelectic list and Bob K. thought it would be fine with only 4 wires but did admit it was somewhat unorthodox. I have more wires that just the 4 in the photo and have 3 row of breakers. Luca made a good point that if were to do this I should give some extra insulation by adding some tubing around the wires.

I think based on the inputs I will tackle this by making a stand off that is attached to the panel but not the bus bar.

Again thanks for all the inputs. I get 17 hours back home Christmas day before a trip on Sunday. It sucks being away from home for the holiday but it is nice getting folks to there destinations this time of year.

Merry Christmas from Osaka!

Extra insulation would be fine, but there is an interesting point to your set-up.

If the insulation did fail at the clamp, since both the clamp and the wire are at 12 volts, there would be no big spark or release of smoke...

All you would lose would be the action of the by-passed CB.

You could almost say it's safer than a grounded clamp....

Default My solution

While on my trip over the holiday I was able to come up with a solution to support the wires going to the CBs. A couple years ago I picked up some stand-offs at an air show from a surplus seller. I am not sure what they are for, there is a part number but they are pre-drilled and the post is threaded for an AN3 bolt, they work like nut plates, the bolt goes in easy then gets tight. There is a tiny inspection hole to make sure the bolt goes in far enough I assume, kind of like the tiny hole in a D-sub pin. I have used these little threaded posts other places, kind of handy.
