Colyn,

Every electrical component rated for aircraft use (and most others) have the
amperage rating firmly fixed to the unit. This information is also in the
owner/user and/or installation manual. As far as I know, there is no
consolidated listing. Even equipment of the same make and model change their
power requirements over time, so this would be a difficult list to keep
completely current. I got my info directly from the equipment I've
installed/intend to install. I had to actually measure the current draw for
a couple of items (one was the vent fan for the IV-P as I recall) but with
some time and effort, I have a pretty good list. Unfortunately, it's
virtually useless to others unless you're using identical equipment.

Sorry,

Bob
