He had me IMPERATIVELY remotely switch blocks with the plug = EARTH positioned identically to the photo (from the front). At the rear, the EARTH socket positioned well (down). On receiving my order, the shipping carton photo as everything is presented on the auction site, following my selection criteria and my order. Several days later, ... blocks unpacking switches for setting up ...; I maperçois that plugs "EARTH" at the front and rear are placed UP blocks and not down as pictured and as he needed! I have not been able to make functional connections as planned and the final appearance of ALL OPERATING not look the best !!!
