Confusing electrical system on my 410

[gibbs789]

I got a 2021 Sun Odyssey 410, and I'm a bit confused by the setup. it has a single 50-amp shore power inlet and a 20-amp input from the solar array. Near the main panel, I've noticed three smaller junction boxes and each one has a couple of breakers. also there's a compact, 15mm wide, 20-amp, 2-pole breaker that seems a bit unusual. I'm not sure of its original brand or type.

Anyone with a similar setup, or tips on tracking down info for these compact breakers? Any help would be awesome, thanks!

Totally normal setup! Your 50A shore, solar and multiple junction boxes are standard. That "unusual" 15mm breaker is just a common DIN rail type MCB used on European boats. Check your owner's manual for diagrams or search "marine DIN rail breakers" for info.

Agree, looks like a pretty normal setup with the 50A shore power and 20A solar. Usually, the smaller boxes take care of solar and extra circuits. That tiny 15mm breaker is likely a DIN rail type to save space, Homeline or Square D probably made it.
