I was poking around under the panel and saw that, while most of my CBs are 7274s, one of them is a 2A 7277, a slow blow.
In my extensive internet "research" [1], it seems that slow blow CBs are used to ride out inrush transients, like for flap/gear motors or incandescent bulbs.
Thing is, my plane doesn't have flap or gear motors. In fact, pulling that breaker doesn't seem to do anything.
So, why would this have been installed in the first place? I haven't traced the wires yet.
From left to right, I have
CB #1 - 10A - gtr 225
CB #2 - 5A - gtx 335
CB #3 - 5A - ???
CB #4 - 1A - insight g2 engine monitor
CB #5 - 2A slow blow - ???
CB #6 - 1A - plane power voltage regulator
fuse #1 - 2A - aileron trim
fuse #2 - 15A (one label says 15, one label says 10...) - the entire avionics bus appears to be downstream of this fuse
fuse #3 - 20A fuse (label says 10) - position lights
fuse #4 - 5A - ???
fuse #5 - 30A - landing light
fuse #6 - 10A - strobe
