I'm in the process of installing an entire new 12V system into my Super-Tauk.

I'm using this BlueSea general schematic as a guide, except I wont use the ACR or the dimmer.

If memory serves correctly, a past thread describes using a 30 AMP fuse between the Batt switch and the (+) distribution buss.

Could it be the generalized nature of the BlueSea schematic that it's omitted?

My system will have a 8" x 16" panel with:
1. a Batt 1-2-Both switch,
2. 10 circuit (+)Buss, 10 circuit (-)Buss
3. a 6 circuit ATC Fuse panel for Switched loads
4. a 6 circuit ATC Fuse/Switch WeatherDeck panel for Un-switched loads [surface mounted exterior access].

Except for the Engine Start/Tilt control, the 'House circuits to the stern are [+/- 12']:
(2) Bilge Pumps
(2) Lights [Stern Nav LED, Stern/Deck illumination LED]

All other circuits start and terminate in the console will be no more than 20amp ea, or less.
[GPS, VHF, Fishfinder, Stereo, Nav LED, Foredeck LED, Console Interior LED, 12V Charge port]

The Batt Selector is mounted within 12" of Batt's on one end of 8"x16" panel, then 'Switched' loads FuseBox, then the 2 Buss' distribution bars will be at the aft end of panel.
The panel itself is accessible from the front seat lid opening of the console, immediately next to the two batteries.

In my design, is a 30 amp fuse necessary/recommended between the Batt Switch and the (+)distribution buss?

Thanks for reading and input.

Except for the Engine Start/Tilt control, the 'House circuits' to the stern are relatively low amperage and +/- 12':...
