I want to put a external waterproof single wall socket on the outside of my porch wall,I've noticed the waterproof socket with the door flap type are only waterproof without the plug in (?) I take it you can't leave the plug in when raining or am I wrong? So am I right saying if I got these two in the picture,I can then leave the plug in the socket regardless of the weather?
