Marina manager and a trades type guy revisited the marina electrical issue(s) today – as more than a few boaters are experiencing issues. Still a mystery.
Meanwhile – I spent some time going over my AC systems (boat and boathouse) to ensure that I am not a part of the problem and to inspect for damage by the problem.
I noticed that the outlet (in the boat house) that I use for shore power – was a bit brown – so overheating. I opened it up to inspect. I found a very burnt neutral wire. Its hard to say whether I or the marina caused this but given that the marina definitely burned out 2 devices on the work bench – I believe that this was caused by over voltage from the marina.
It does not help that the wire was braided so I reworked the whole thing with new kit.
I now power the boat house and boat independently with their own cords to the marina shore power. I also use a different leg for each (there are two 120v legs).
In the boat house I removed the old socket (and the old power bar) entirely. I replaced with a new 3 socket ‘pig tail’ which has an inline unit for cutting out when some faults detected like reverse polarity or short. So no braided wire connection like above – just non-spliced off-the-shelf cords.
I cut a little notch in the door to make this work.
I purchased a socket tester at the hardware store and tested some of the 120v sockets on the boat (I forgot to do 2 of them so I will do them tomorrow).
I tested the two I had redone and they were fine. I then tested the socket hidden in the cockpit. This one faulted (“HOT/NEU REV”). I have never used it – thankfully.
I took it apart to inspect. The inside just fell apart in my hands. First the cover then the entire guts.
My first thought was to replace the guts but I have decided that I do not need a 120v socket back there so I will remove it – including the wire running to it. I will also inspect the junction box that (I believe) this is sourced from.
I gave the marina manager the socket tester and suggested that he lend it to the other boaters to test their 120v sockets.
