50 amp shore power cord

[2texoma]

Yeah, I'm just concerned now that this one is marked 125/250 and is not, I don't want to make this mistake again. The 250 is still a 3 prong plug and looks the same, where is the 4th wire going?

Russ you need to either have Larry pick up the one he's found (very good price but likly no warranty ) or buy a new one (with a warranty ) ,take your pick. Posting ambiguous discreptions will result in ambiguous answers that may damage the electrical system at best or kill somone at worst. Some things just don't lend themselves to online troubleshooting unless the inquirer already has a working knowledge of the subject. Sell the cord to somone who understands how to wire electrical devices and can reconfigure the cord.
The answer as to "where is the 4th wire going" is;
On the 125v/250v 50 amp cord pictured,"to the metal tabs marked G on both ends"if somone hasn't been monkeying with the cord.

The markings on the plug that say 125/250 50A is a configuration design, there are 250V 50A plugs as well and these have a different plug configuration (they will not mate together). your boat uses the 125/250V 50A configuration... That being said and the fact that you have only 3 wires, leaves you SOL! There was a guy by me I was talking to last week that was selling a 50' 125/250V 50A cable, he said it was 4 years old (all molded ends) and was asking $275... I can see if he still has it?

Thanks Larry, I have a line on another one for $100 in RI.

If the plug and receptacle end say 125/250 and they are molded ends, factory ends, you won't see 4 blades, the outer shell is the ground. read the cable itself, it should have marking's on it, part of it should say 6/4 marine cable, if so, it does have 4 wires, you may just have a bad end, easy to replace for about $100.00.

Thanks Bob, they are not molded it's an older cord. I have had the ends off, there are only three wires. The end connectors have the ability to connect a fourth wire but it's not there. Like Larry said, I'm SOL. Thanks for your input though.

There is nothing ambiguous about the question and the descriptions are left to individual interpretation. Therefore some responses are definitely ambiguous, including yours, what does not have more than one meaning or subject to interpretation? But no response is going to harm the electrical system or kill anyone! No one is monkeying with or even suggesting any modification. I know enough and actually have a bit of common sense, you don't know that so you'll just have to take my word for it but I appreciate your concern.
