This LC1 D25008 is the switch that changes you automatically from shore/genset
power. The wiring of this device can be somewhat confusing to the novice. If
you are unsure, get an electrician.
needs to be replaced. It probably melted due to corrosion on the bare ends of
the wires. This causes heat and then fire. You will need to trim back the wire
cable to check for damaged wire.
I had two of
these devices fail on Cream Puff and because of this I opted to replace it with
a manual switch. Since we live on the boat full time we are either at anchor or
on the hook. Changing over the manual switch is not a big deal. I installed one

Subject: [AmelYachtOwners] Shore power contactor burnt out
yesterday I connected to 220V shore power, sockets worked as usual. Then I
switched on the 220V battery charger and aircon. A few seconds later all
220V power stopped and there was a burning smell in the galley and the large
port cockpit locker. No breakers gone on shore or the boat. No
possibility to get shore power working again. The inverter still works
but did not try the generator (due to an abundance of caution).
Today I traced the shore power cable to the forward end of the large port
cockpit locker, behind the insulation and removable end panel. There was a lot
of ash, which was never there before (I clean every year). I opened the
grey box that the mains cable terminated in, and there was evidence of melted
electrical insulation and a lot of soot. Inside there was a “device” with the
labels “Telemecanique” and “LC1 D25008”. I googled this and found it is a
“contactor” (I never heard of this word before).
My questions are: did this device fail due to age and simply needs to be replaced
(along with damaged wires), or did it protect me from something badly wrong and
there is another problem elsewhere (battery charger or aircon).
I am waiting for an electrician, but maybe someone else has some advice?
