Shore Power Cord Stuck

[SailingStevie]

One of my shore power cords is stuck and will not pull out. The plug will turn to unlock and turn to lock but it will not pull free from the inlet to the boat. My boat has two, one for main AC power and the secondary for AC power to air conditioning systems. The lower air conditioner inlet is the one that is stuck. I've researched it some and found that it might be self-welded into the adaptor because of an arc... With this said, if it's welded in how can I free it or remove it and replace. The boat is a recently acquired vessel for us and we are unsure of the history of maintenance on the shore power cords. I'm suspecting the connectors have not been maintained over the years. Any suggestions would be appreciated. I'm trying to avoid calling the marine electrician for something that might be a quick DIY job.

Sounds like it has overheated. You'll likely have to cut the end off the shore power cord and install a new end plug. Remove the vessel's inlet as well and replace it. You should be able to get to the screws from the outside that secure it to the vessel. I'm assuming this is a 30 amp service?

Check the condition of the plug at the dockside end also. If there is any discolouration around one of the contacts, replace that plug too or the entire cord. Don't take any shortcuts here.

This would be a good time to consider upgrading to the SmartPlug. Best plug on the market for recreational boating IMO. Helps prevent what you're going through now.

While you're at it, check the condition of the hardware on the other circuit as well.
