Does anyone happen to know the amperage of the circuit breakers built into the 12v panel? It's a Scheiber panel with switch modules, each having three switches.  Also, does anyone know what these terminations are for?   |

Open the panel and look at the trip fuses on the inside. I believe ours are 10A, but I'll check it today on the boat. It should also be listed in your DC wiring schematics in your owners's manual.

Funny, I added a picture to ask another related question. It didn't appear at first, so I didn't ask, but now it's there.................
Anyway, I purchased another switch module so that I could add circuits. There doesn't seem to be any amperage markings anywhere.
The schematic in the manual is difficult to read, as it was probably photocopied too many times over.

My SO 40 has those terminal strips attached to the left interior wall of the instrument panel cabinet. They provide +12V and 12V common fan-out for several circuit breakers, including "Instruments", "Radio", and "Plotters". Brown wires are +12V and blue wires are 12V common, I recall.
On Voyageur, these strips are the 12V source points for the NMEA-2K bus, VHF, stereo receiver, & chartplotters.
Your strip with the yellow/green wires is likely 12V common/ground, all paralleled on the top layer. The bottom layer of that strip appears to have 12V common at the left end and +12V (from a breaker) on the right end.
If anything like the SO 40 strips, the other top strips has 2 3x2 rows, the three left rear wires being paralleled and the opposite side unused tabs also in the same circuit. Ditto for the three right rear wires and one on the forward side, to the right, and the two unused tabs next to it. The terminal strip behind it is likely 12V common, with all tabs paralleled.
Circuit breaker sizes should be visible on the side of each breaker, once dismounted. If like the SO40, these are standard Carling breakers, available from many sources, including Blue Sea Systems in the US. I changed some out when the power distribution was rebuilt on Voyaguer 2½ years ago.

Interesting.............they measure 120v on my multimeter. There is no electrical schematic for the 120v system in my manual.
