Shore Cord Check

Just a reminder to check your shore cord sockets and plugs at both ends and any couplers in between.
I just replaced a socket & wire from helm AC main to the socket on side of boat.
There was char on the inside wall panel from the socket melting.
This happened on a Marinette.
I spray all connections with
Rid Ox at beginning of each season.

NOTE: You MUST turn OFF the main power switch at either the boat or at the dock BEFORE pulling the plug or (even worst) inserting it.
Think of the amps that will flash between the prongs of the connector as the AC unit, refrigerator, battery chargers, etc all come on line together!

That is an excellent point, people get used to plugging in and unplugging low draw 110v wall plugs and forget how much amperage can be involved on our dock side power cords !! It really is important to kill the breakers designed to do this before hand.

And don't leave a live (plugged in to the receptacle, with the boat end open) lying on the dock for someone to bump into the water. My dopey neighbor does this all the time.

Also don't leave the power cord plugged into the boat with the inverter on! The male end prongs will be "HOT"

I've never installed an inverter but I'm fairly sure you want to open the path to the main so you never feed voltage back into the dock and never have hot male plug. Same idea for running a generator on board.
This also applies to residential generator. Never feed back into the utility company.
