Avionics Breaker size

[TimJBennett]

Van's wiring kit has a 10 amp breaker for the avionics. I have run that to an avionics bus. From the bus I have run to the EFIS, AP74 and EMS.
Is this OK?

Remember, breakers protect wiring, not components. So if all of your wires after the breaker can handle 10A, you're OK.

A D100, D120, and AP74 have a max combined draw of about 3A with no battery in the D100 and about 4A with a battery.
