I posted this on another thread, but didn't get any responses, so starting a dedicated thread.

Anyone got any ideas what this is (see attached). I hope it is something that has been replaced - my concern is there are 2 sockets and it seems a striking coincidence that there are 2 leads with corresponding plugs next to it and they are not plugged in.

I haven't found anything fundamental not working but I would like to know what it is and if it should be used. I would probably remove it and tidy up the wiring if not.

The only clues I can offer are: It has no writing on it, it is mounted on a single screw and will spin round 360 deg, and was clearly designed to run hot. It has a heat sink style body and the plugs look high temp. Oh yes it has 2 fuses - 15 amp built in.

Thanks

In to a big mess of wiring near the stbd batteries, I haven't followed them right back yet. They could go to the batteries or back forward the instruments and fuse panel. I was wondering if it could be an old battery charger? It now has new beefy mobitronic ch.arger

Princess used to use a 240 volt AC to12 volt DC power supply for fridges, has it got mains in ? could be a similar job though it looks 12 volt only.

Would say it's trace the wire job.

The "kettle lead" connectors are 240V, and there's two of them, so my guess is that it's a 12v to 240V transformer with two outlets, for running mains stuff off the batteries.

Yep there is a ring main, there is also a fridge but this seems to run from 12v.

That would be really useful if it has. The only puzzling thing is it has no wires going into it. I suppose of the floating leads could go to the bateries and one to the sockets. Looks like it is wire tracing time as many have suggested
 
It wont have the same plug for 12v in as 240V out, unless a home made bodge job, so maybe some kind of power regulator if the previous owner had computer stuff on board??

I doubt very much if those are 240v "outlets" on the box as they are male connectors, which would be live to the touch. You can see the plugs are female. So I don't think the answer is that it is a 12 to 240v inverter.

Good point there.

Looks like those are power IN sockets so where does the power come out?

I think its a bit of a Heath Robinson episode so I would disconnect myself.

Would love to know what is it does too now!!!!
 
Any other connections to it? All we can see here is two 220V AC fused inlets. What goes in must come out, as a general thought. Two separate AC inputs might be one from shore power and one from a generator or inverter so if there's an AC output as well, then it might be an auto switch...

Other than that, two inputs implies 26A @ 220v = 5.7kW. No output would mean you have a very compact 5.7kW heater (hence the heatsink, but you'd notice the boat was abnormally cold with it unplugged like that) of maybe a sub-ether hyperspace radio. If you are no longer receiving messages from intergalactic aliens, then it's probably the latter.
 
are the floating connectors coded ? do they have a number or label on them,
sorting where these wires go to, would clear up a lot

as the unit is not connected anymore, perhaps you could get it out, and make some more pictures,
looking at these pictures (also under the heatsing (?)) it might be possible to recognise the cirquit and know what it could do.
how many amps are the fuses ?

are you sure there is no other connection / terminal posts on the other side ?
If there is only these two connectors,
then I guess it is a home made thing, with a same connector for input and output, so a dangerous situation for whatever it does.

can't you just "call" the previous owner ?
I know, that's less fun on here :)
 
They are 320 connector as someone said but interestingly that's the c15-16 version of the 320 (you can tell by the plastic block in the part on the black box, which requires a plug with a valley in it to mate with). This c15-16version is rated at high temperature (120deg, I think) and used on kettles.

So it's gotta be some homemade bodge thing. Not an inverter because there is no high-current 12v supply and becuase the pins are exposed as someone said, and there wouldn't be 2 x 230v connections anyway on such a tiny inveretr. The wiring to the plugs looks home-made. As already said, you need to find where the wires go, or unscrew the lid and see what's in the box
