Bert,
I agree with Dale. I have an exp buss and although it has some nice features, I would not use it again despite the fact that mine has worked well for 260hrs. Like Dale I also have an external master because my current demands sometimes exceed the 40 amp limit of the exp buss. I have the Exp buss master wired in parallel to provide some redundancy for a failed master solenoid.
One thing that I have noticed is that the rated amperages of the fuses are not good for their rated values at continuous duty. My 100W landing lights would trip the 10A "landing light" circuit after about 5 min of continuous use. So I had to install a separate buss, separate fuses and switches for all my high current items.
So, back to your problem. I would be very suspicious that you are exceeding 40 amps and tripping the master circuit somehow. Don't forget that battery recharging ALONE can exceed 40 amps if your battery is low (I see as much as 85 amps for a while if I have let my battery get really low - though normal daytime draw is around 20 amps(electric ignition, coils, pumps, panel etc)).
Also, Like Dale mentioned - really double check the crimps and connections on the Exp buss ground and master switch ground. If you have the switches mounted to the board like I do, then you have noticed how tough it is to tighten and loosen those screws on the side of the switches to attach the outgoing wires. Those screws often will work loose if there is any sway in that wire. Loose screws there will cause trips of the circuits.
Finally, I have ongoing problems with aluminum shavings getting onto or under the board and causing shorts. As much as I try to build a sticky-tape fortress anytime I am cutting or drilling on or around the panel, there is alway a shaving that gets lodged under the board the wreaks havoc until I can find and dislodge it.
Good Luck,

[quote] Bert,
It sounds like the master relay on your EXP buss may be opening after a few minutes. This could be because of a poor connection in the energizing wiring circuit to the circuit board mounted relay since Control Vision said the unit checked out OK. Suggest you check out all the crimp connectors in the circuit and the master switch.

I have been flying for three years with the EXP bus in my 6A with no problems but I have an external master relay and did not use the EXP circuit board mounted relay.
Paul,
I agree with you...Knowing what I know now about designing and installing 'a good old fashioned buss bar and breakers' I would not use the EXP but it has served me well so far. Doing it again I would probably go with auto type blade fuses.
