ECN Forum Forums Photo Discussion Forums Photos for General Discussion Trade Practice - Why 'Flip' the Recep?

I'd like to -again- post a pic especially for the guys who are new to residential work.

Let's forget, for the moment, the silliness of placing a receptacle behind a door. I'd like you to note that one recep has "ground up" while the other is "ground down." Care to guess why this was done?
