Shore power off - circuit breaker

I was running my electric heater on shore power when the shore power just shut off. Sometimes the marina power shuts off but this time I think it is the boat as the lights are still on, on the shore power stations.

I checked the circuit breaker near where the SP cable connects to the boat and noticed it looks like this, which I assume is off. I have never looked at it before as I cannot see it because of where it is positioned unless I take a photo.

What does the yellow T button do?

Flicking the switch to show green does not give me power and neither does trying other power outlets on the dock.

The shore power light on the switch panel has stayed off.

Is there likely to be a fuse or another circuit breaker perhaps behind the instrument panel where the power is distributed to the sockets, water heater and charger?

My normal process of looking at the problem would be to get out the volt meter, but for me that's fin with 12v but I'm not keen on sticking the volt meter into the 230v AC.

Going to be a cold night onboard :-(

Re: Shore power off - circuit breaker

The 'T' switch is for test, it looks like a GFI outlet. Turn the switch all the way off to the bottom then flip it back up to the top and see if that works

Re: Shore power off - circuit breaker

Thanks...

I have finally tracked down the problem.

One of the pins on the shore power connector on the boat has lots of corrosion on it. It was very difficult to remove the plug. As I could not get access to clean it, I sprayed on some electrical cleaner and added/removed the plug a few times to try to rub off some corrosion.

Now it works again.

There was a little black around the pin hole on the cable, so I guess the connection has not been too good and heat blackened it.

I think for safety I might replace the shore power connector and the plug.
