Orientation question I usually mount mine so the ground pin will be below the L&N blades because most plugs using the side entry scheme for the cable have the entry point close to the ground pin, and I prefer my cable to hang down rather than stick up above the plug.
On the side entry plugs the manufacturer trims the ground wire a bit shorter so the ground wire cannot touch (and possibly short to) the L or N conductors or blades when the hot compound is injected into the mold. To have the cable entry between the L&N blades reduces spacing in the plug because the ground wire must pass between the blades. Therefore less movement during molding can be tolerated. The L&N conductors must be trimmed, and that wastes about 5mm of cable on each assembly.
