Are those 12v or 120v circuits you want to add? And where is all that power going to come from? 5 x 15A = 75A of additional power that has to come from somewhere. Even if 12v circuits, your converter/charger is going to have to produce it, or the batteries if not on shore or generator power.
I started digging around where all of the electrical components are and I can't find another Distribution center other than the 12V fuse panel that is associated with the Intellitec unit and it appears that all 12V components run through that: (Thermostat (5 Amp), General Purpose Lav (15 Amp) Galley (20A), Bedroom (20A), EMS 12V Pwr (5A), Accessory Pwr (15A), Water Pump (10A), General Purpose S/O (20A), Appliances (20A), Lounge (20A), Front O'HD Pwr (15A), TV (10A).
We have a WFCO 65 Amp Power Converter.
I guess I'm stuck on how anyone would install tank heaters. I was going to keep each circuit at no more than 15 amps. In reality I would be using Ultra-Heat tank heaters and should be using exactly no more than 45 amps if all of the heaters were running concurrently.
Am I going about this all wrong? Surely I should be able to accommodate these 12V tank heaters, I guess I just need someone who has been there and done that or has more experience than I to get pointed in the right direction.
