Appropriate procedure for connecting and disconnecting from Shore Power - Maxum Boat Owners Club

Amiga3300 · Yesterday, 06:06 AM

My boat is a 110v in Australia, so our shore power is 240V. That said my boat has a converter for converting the 240v to 110v (signed off to code by a marine electrician), so I don't think it will affect my procedure, just as an FYI.

I understand the general procedure is:

Connecting Shore Power
1. Ensure shore breaker is "Off"
2. Ensure boat breaker is "Off"
3. Connect cord to boat outlet
4. Connect cord to shore outlet
5. Flip shore breaker to "On"
6. Flip boat breaker to "On"
7. Check for Reverse Polarity

Disconnecting from Shore Power

1. Turn off breaker on shore
2. Turn off breaker on boat
3. Remove cord from boat outlet
4. Remove cord from short outlet

Is this sufficient, or (as I suspect) there is more to it? For example:

In the attached picture, should I be turning the silver dial in the bottom right hand corner to "Off" and the Shore Power 1 switch in the top left hand corner to off? If so, I assume I do that after checking for reverse polarity (step 7)?

Yes the converter will do as you say. Your procedure for connecting is correct. Regarding you disconnecting procedure #1 and 2 should be reversed as the load side should be unpowered first. Additionally #3 and 4 should be reversed as leaving the cord connected to the shore power adds risk if you forgot to turn off the shore power breaker. If the cord were to get dropped into the water a shock hazard could occur.
