largest wire accepted by most avionics tray connectors.
5A breaker is less expensive than a 2A breaker and
is also fine.

Thanks Bob!!
Since I had a little time before your reply, I checked with the Honeywell site
regarding the transponder. What I found was what I needed, in a back-door sort of way.
They said (Honeywell) the made a direct slide-in replacement, using the old tray and wiring,
of the KT 76 with the new digital KT 73. A quick check of the specs on the KT 73 says
it has a max current draw of 2.5 amps.
My thinking is since the 73 is a direct replacement of the 76, and the 73 uses a 2.5 amp
draw.
Regarding the best size, I've got (7) each 2A Klixons and a (4) each 5A Klixons. None of
the Klixon breakers have a home yet....that's what I'm doing, assigning breakers to their various
tasks. I actually have (3) each 3A breakers (plus other amp sizes).
If you think a 5 amp would be okay, then's just I'll go with that!
Plus, regarding wiring size, I've got a 600' foot roll of 18 ga. twisted pair tefzel. I don't have
any 20 ga AWG on hand.
Thanks again, Bob

If you're putting new pins on the wires, 18AWG will
crimp only into larger of the two pins shown on
this data sheet.
