Breakers, fuses and circuit protection
Raymarine recommends that you fit a thermal breaker or fuse for
the camera at the distribution panel.

All models
5 Amp.
Sharing a breaker
Where more than 1 piece of equipment shares a breaker you must
provide protection for the individual circuits. E.g. by connecting an
in-line fuse for each power circuit.

Where possible, connect individual items of
equipment to individual circuit breakers.
Where this not possible, use individual in-line
fuses to provide the necessary protection.
