Shore supply breakers will not reset

[Steve_Sigma33]

The shore supply breakers on the back of the connection point will not reset. I’ve checked inside and there is no sign of corrosion or anything obvious causing a short but I am wondering if the red bulb at the top of the unit acts as a fuse! Does anyone have experience on this type of unit?

Any photos so we have a better understanding

Just trying to make the photo smaller to attach!!

If I phone you can decide photo size when you upload.

Should be visible now

Not sure why it’s tripping if you have your boat unplugged from
The socket. May be ingress into the outlet socket.

According to the website it indicates the presence of a supply voltage.

I guess if there's no light there's no power to that socket, but where are the circuit breakers you mention ?

If its part of the mooring its not your problem.

It has rcd breakers on the back.

Well that’s the interesting part. Management company said it’s not them, marina said it’s not them either. On a private mooring in Port Solent

If it will not reset with nothing plugged in it’s up stream of the actual socket , so either marina or management, most common issue is water on back of socket, does not have to be dripping wet just moist

 

[luke collins]

Give it a good spray with wd40 back and front and see if it will reset.

What’s it wired into? It looks like a fixed electrical installation. I am very surprised that the marina is saying it’s not theirs, as it must be hardwired into their supply. Do you get charged for your electricity?

Rcds........plural?

I 'd expect an rcd and an mcb.

Both tripped? What happens if you try to reset them

Are you sure that the problem is not simply that there is no power supply to the box? Where does the power supply come from.

Most marinas will lend you a tester plug to check the socket if they are not free to walk down and do the test themselves. Is it just this socket or does your shorepower work if plugged in elsewhere (appreciate on a property owned pontoon you are renting might not be other sockets) is the socket the responsibility of the PS property owner? You refer to a private mooring by which I assume a property owned pontoon?

Yep, meter in a cupboard by SSE

Does the Marina take responsibility for the meter? Or is it electrically connected to the property that owns the pontoon?

You could have a faulty RCB/MCB, can you isolate the supply at the meter end ? If so, isolate it and see if the breakers will reset. If they do, they are OK, if not they are faulty.

If the breakers are OK, the fault must be in after the breakers, so in the socket or somewhere in the post. If you can isolate the post (should be able to) take the socket and light off of the front and check the connections are sound and dry, spray with WD40 or better yet ACF50. If that doesn't fix it you'll need to take the enclosure apart and do the same.

If in doubt, get an electrician in.

Agree with PauI, especially the last bit!! However, I am a bit confused by some of this. I am not entirely sure that the OP means he cannot reset the breakers. The type of breaker and RCD fitted in these units will reset (Make) even if there is no power to them. Do the breakers trip immediately he tries to close them, both? or does just one? Does the OP perhaps mean that with the breakers made there is no power? In which case the fault is probably a tripped, main, circuit breaker in the the same cupboard as the meter. Has that been checked? It is unusual that both the Circuit breaker and RCD would trip, if that is what is indeed fitted. If both have tripped, and possibly also the main breaker I have mentioned, then it smacks of a heavy short circuit in the socket or unit.
I would suggest that the mooring and associated equipment is the responsibility of the property owner. If that is not the OP then I would further suggest that he stands back and let them sort it out. 1)If he is not sure of what he is doing. He doesn't want to risk personal injury, or worse. 2) he doesn't want a bill for something he didn't do, but has interfered with!
A picture of the breakers would have been a help!
Edit: just on the off chance, some circuit breakers require the lever to be pushed down Hard to engage the latch before resetting. I would not have associated them with this equipment. BUT!!
