I foresee a LOT of cutting, stripping and crimping in your immediate future

Yes, the back end with DIN rail gets a piano hinge so that the console drops down at the front. It’s gonna be too heavy to just let it drop down I am considering 1/8” Dyneema attached to gas springs or something fancy but may just use a cleat instead haha

What are those blue sea blocks in the DIN rail photo, grounding blocks?

I designed these panels on the computer and had frontpanelexpress.com make them. They supply the CAD software for free.

The BlueSea Systems blocks you see are their dual busbars that I use for AC. If you are familiar with my diagrams: the leftmost one is the input bus, followed by bus 1, 2 and 3 (normally bus1 is out1 and bus2 is out2 of Multiplus and bus3 is a bypass breaker). All those are 240V L1 and L2 only. The last three are used on Autotransformer outputs that make new neutrals for 120V service. It’s where the distribution breakers get their power from.

Do you have an electrical schematic?

Just curious.

Here is the AC schematic. It is for US 120/240V powered boats. EU powered boats don’t have the autotransformers.

The two parallel inverter/chargers aren’t just for doubting the power; they can also be configured to do frequency conversion (one converts shore power to DC and the other takes that DC and makes AC for the boat.

The bypass breaker allows switching off the inverter/chargers like when you are not aboard but want to run a dehumidifier etc. You can also use it like the OUT2 on the Multiplus units, i.e. only get power when shore power or genset power is available. This allows full power output from a genset while the OUT2 ports of Multiplus units are limited.

Edit: the distribution switches are actually on the distribution panels and select which bus for that group of breakers. The breakers are spread strategically, i.e. water heater and A/C are all on one of them so that it makes it logical to use bus2 or bus3 for that group when on shore power.
