That is not a 240 volt ( nema 6-20R ) Recepticle and you will not be able to use that plug for 240 volt. It is not terminated properly in more ways than 1. Your wires are barely under the screw and you have a "dead short" on 1 side of it with the white and red wires together. Please see your other post as I Have responded there as well. You really need to critique yourself M8, because you are swimming in dangerous waters.
