I used Bob's Avionics ground bus and liked it. The only difficulty, and it's no big deal, is the Comm grounds. Both of mine (A210 and 430W) require 18 awg wire. So I just ganged the 18 awg wire into 2 pins with 20 awg wire using solder sleeves. No big deal, easy to do. Nothing else on my panel comes close to the limit for the pins except I do have an electric nose lift (10 amps max) that is not grounded yet. I have been debating putting this on the bus with 3 20awg wires/pins. Bob?
