Here's a tough one for everyone because some times it does and sometimes it doesn't. We are out in Malaysia
and have to use a step down transformer to decrease the voltage from 220 to 110. When we pull into a marina and the electrician comes and hooks us up to shore power
, when we flip the switch inside the boat
, we blow the circuit breaker on the dock
. When we were in Kudat, they hooked us up the the power circuit for the boats in the yard. Same thing yet when they hooked us up to the main circuit panel for the yard, we had nice 110(out of the step down transformer) and when we flipped the circuit panel switch, all was fine. We had 110 power. Same wire. When I use my generator
, the electricity comes into the boat
through the same cords and it charges the system just fine.
When we were in the Philippines
, we found that they don't use a standard ground wire like they do in the US. The step down transformer I brought from the US required it so I had to buy one made in the Philippines
with only two prongs on the plug
. It worked fine while we were there but the one from the US would not work
. Our wiring
worked just fine while we were in Fiji(almost a year).
What confuses most people is that it works when on our generator(same wires)but not on shore power
, plus in some places it works and others not.
Some times when we connect the wires to the marina panel, we have the "reverse polarity" light come on on our circuit panel. We reverse the two wires and all is fine yet the circuit breaker on the dock
still blows when we flip the switch.
Anyone got any ideas as to what is going on. Everyone out here keeps making suggestion but we have already tried what they are suggestion.
