The pilot fuse is set to handle various pumps. Which pump
you have and it’s draw may be much less. Some pilots are under 10a. The Garmin
fuse is 40a.
It’s also possible the pilot runs through a relay. And the wire from the brraker is only triggering the pilot. Not powering it.
I often run a 20-30a breaker to a bluesea 5025 which then feeds all the nav gear
. But the pilot is always done seperate for me. And often the vhf
if enough breakers.
