WeatherDeck™ Waterproof Fuse Panels - Blue Sea Systems
this is the blue sea water proof panel, it even has separate illumination back lighting. this could be used as the "indicator" that power is on that you can see from the cockpit, and each one lights separately, red off green on and no color for a blown fuse.
I ordered a 6 position, white, circuit breaker one of these earlier today.
Using the red vs green as an on/off indicator is a great idea. From reading the docs I thought I could choose red or green and that this was always on as a backlit label. Do I have to modify it to work with the color as an indicator or is it designed that way?
you said ogm mast light, if that is a tri color they even sell double switches for that panel so you can set one switch to select anchor or tricolor,
My OGM is the tri color / anchor / strobe model. For anyone reading who does not know, it is fed by three wires, a common negative and two positives. If you power one of the positives, the tri-color goes on. If you power the other, the anchor goes on. If you power both at the same time, the strobe goes on.
Blue Sea has a SPDT on their web site for this panel, so I could push it one way for tri-color and the other way for anchor. I then need a second switch for the strobe that sends +12VDC up both wires at the same time. That turns off the tri-color and flashes the white anchor light.
I ordered a six switch panel, so I'll probably wire the OGM anchor and tri-color in teh cockpit, since they are the same switch. I'll put the least important part inside. That's the strobe ;-) Yeah, I know, I suppose I should make it easy to get to. But heck, the VHF with the big red panic button is below, so why not put the strobe below too!
you just need to have a mast head main switch. if it is a steaming light with deck light ( steaming light by CG regs is called a mast head ) then its just 2 switchs
Yes, one switch each for mast head light and deck light.
I probably will have the following switches in the cockpit:
1 - Deck level running lights
2 - Tricolor at mast head / Anchor light
3 - Masthead (steaming) light
4 - Foredeck (spreader) light
5 - Instrument lights
6 - TBD
(probably I'll save it for when I install cockpit lights)
If I ever need another switch, I'll just wire the instrument lights to always be on or move them below. They use so little power I might just wire them to always be on anyhow.
On a side note, I may just figure out a way to have the mast head light come on whenever the engine is running. There is no down side to this, since the engine will be making power. I would still have a switch, but then I can move it below since in theory i should never need to get to it.
to size the feed just add up all the wattages on the leds and add 25 %. that panel does have blade type fuses but you would only need 5 amp fuses if everything is led.
The masthead and foredeck lights are halogen, I'll have to look up to see what their current draw is. Probably not much. The instrument lights in the displays and the compass are tiny. Everything else is LED.
The big panel inside comes with 15A breakers, that should be fine to feed this panel.
