The button on the circuit breaker (CB) for my master relay (which I think is

the same as a "battery relay" in the Z diagrams) broke off and I want to

replace it. The CB still works. The I want to order one before I

dis-assemble my panel, but can't read any numbers on the unit. The numbers

are either not accessible or worn off. So....what size circuit breaker might

be associated to the typical master relay...2 Amps?

   I'm not aware of a need for a circuit breaker in the

   master or battery relay control circuit. If you have

   a circuit breaker associated with this function, perhaps

   it is not necessary. In any case, there are virtually dozens

   of circuit breakers suited for use in aircraft. Does

   your breaker look anything like these?

   This form factor is commonly used throughout the aircraft

   industry and manufactured by at least a half-dozen manufacturers.

   B&C and Aircraft Spruce both sell them. But I'm skeptical

   that your battery relay circuitry benefits from the use

   of a circuit breaker.
