If you need this connector, it is important to know that it is for 16Amp. is aligned. My ship has a 50 amp connection and the plug is a little bigger accordingly. But nobody told me that. I have now ordered the plug directly from "Mastervolt" in the USA.
Actually, power supplies according to the American NEMA standard do not belong to European boats. The open pins on the boat side are American standards, but prone to injury and damage and corrode.
The product worked until it was removed and then reinserted into the boat side receptacle. I disassembled the Marinco socket checking that both phase and neutral were no longer connected with the screws absolutely not tightened. An oversight that is unacceptable for the price at which the item is sold.
