• If you need to extend the length of the power cable, ensure you use suitably rated cable and that
sufficient power (12 V dc) is available at the SeaTalkng ® backbone’s power connection.
Important:
Be aware that the suitable fuse rating for the thermal breaker or fuse is dependent on the number
of devices you are connecting.
More information
It is recommended that best practice is observed in all vessel electrical installations, as detailed
in the following standards:
• BMEA Code of Practice for Electrical and Electronic Installations in Boats
• NMEA 0400 Installation Standard
• ABYC E-11 AC & DC Electrical Systems on Boats
• ABYC A-31 Battery chargers and Inverters
• ABYC TE-4 Lightning Protection
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 is
not possible, use individual in-line fuses to provide the necessary protection.
