If you look closely at the front of a bare(uninstalled)
receptacle, you'll see tiny writing on many that is
legible only when the receptacle is held so that
the ground is on top.Â* There's a major clue for all
the "looks silly with ground on top" crowd!Â*


Â*Â* My refrigerator has a 90 degree angled plug.Â* To minimize stress on
the cable, the wall receptacle needs to be installed with the ground pin
down.

Yet my 20 year old Fedders air conditioner should have pin up.

No A/C plugs are made to assume the unit is mounted higher than the
receptacle so the cord is oriented up.
