Existing reviews of 30A 277V/ 480V Locking Plug, 4 Pole 5 Wire
I bought this locking plug for the portable generator cord. It is suitable to install cables to male plugs. These plug ends are easy to install and easy to use. The positive locking when twisted is also very nice. This is the best quality connector I have ever installed. Installation instructions and diagrams are also provided for the various plugs and receptacles. I will buy more of this plug.
