Re: [Amel Yacht Owners] 30 Amp 125 volt shore power to 50 Amp 125/250 Volt plug?

If anyone has need to use the Pigtail Shore Power Adapter, 30A 110-125V Male to 50A 125/250V Female, you will deliver 110VAC 60htz to the boat. That is the reason that I said Alex has no need for the plug in the link he sent.
"The functional result on the boat is the same as plugging into a 50A-125/250V plug connected with three wires." but what you did not say is that it will only deliver 110-125VAC 60htz to the boat.
Frankly, I do not know what transformer Alex has, what the input requirements are, how it is wired, what its maximum amperage is, and if maybe something has changed since it was installed.
There is a device that will connect to two US type 30A 110-125VAC supplies and deliver 220-250VAC 60htz to the boat. It has 2 each 30A 110-125V Male connectors to connect to the shore power and 1 each 50A 220-250VAC 60htz Female connector to connect to the boat's US style plug. I have one and it will work when each of the 30A 125VAC connections are made to a different 110-125VAC circuit. I used this $800 device once and did not really need it because the marina had both the 30A 110-125VAC 60htz and the 50A 220-250VAC 60htz connections on shore. And, because to use the adapter, the two 30A 125V lines must be connected to a single power source providing from 208V to 250V between them for proper operation...in other words, the marina has to have 220-250VAC anyway, but possibly not 30 Amp connections.
My adapter is similar to this one in function:
I also believe that without a complete inspection of Alex's boat, none of can help him accurately.
