I'm in the process of installing my Zumo XT. I'll be connecting it to my PC-8 on a switched circuit.
According to Garmin, the Zumo XT power cable has a built in, non-replaceable "fuse" (probably more like an electronic circuit breaker) built into the voltage converter. Garmin doesn't provide an amp rating for this circuit protection.
The wires in the power cable that will ultimately be attached to the PC-8 appear to be 18 gauge.
Even if the Zumo has it's own circuit protection, the connection in the PC-8 is still going to need a fuse. For the distance that the cable has to run from the mount to the PC-8, 18 gauge cable can handle up to 15 amps. I don't see the need for a 15 amp fuse in that circuit, since it's a dedicated line to a device that I suspect draws around 3 amps or less, but I'm curious what others have done in this situation.
What size fuse did you use in your fusebox connection for the Zumo XT?
