All of the avionics are on the number 2 buss. We have the B&C 20 amp alternator for this system. Our dual electric system is 12v. We have the following: Blue Mountain EFIS/ONE, Garmin GMA 340 Audio, Garmin AT 480, Garmin AT SL-30, Garmin GTX330 and a DFC250 Tru Trak. The only item not on the # 2 buss is the Dynon D-10A. It is on the #2 battery buss. The biggest consumer is the EFIS/ONE. Our total amperage with all of the avionics on is 9.5 amps. Of course, this does not count the Dynon since it's feed does not go thru the Hall-Effect sensor on the #2 buss. WE have not measured the amps when one of the com transmitters goe on the air, but this is always intermittant and usually is not counted in electrical load calculations. Hope this helps.
