    This is a very old stand alone 30mA mains RCD device, just like the ones in your house mains distribution box. Obsolete part, and therefore best to replace it with the modern standard device. if possible I would fit a “garage” fuse box from Screwfix into the mains system if you have the space and then you’ll be able to fit an RCD plus breakers for your outgoing mains feed into the boat.

    This iOS done like this on newer boats….

    Just my thoughts……
