If you plug in an older 2 prong (No grounding prong) device into a receptacle with a grounding hole and the different size slots - does it matter which way you plug the older two prong device in - (In another words if the device in rectangular for arguments sake and the "longer" segment of the device is below the prongs) Does it matter if the longer section covers the grounding hole or points in the other direction which would leave the grounding hole uncovered. Another way of looking at it does it matter if the "ass" end points left or right?

No. Even older depending on your definition of older may be polarized and in that case it will only fit one way.

Thank you. One of those things you take for granted but nice to confirm it. In this case it can fit/plug in either way.

There are some old, "vintage" guitar amplifiers and other devices made in the 50's & 60's that can be plugged in either way. Use a meter to determine which spade has continuity with the metal chassis. Plug that into the larger of the two slots in the receptacle. With guitar amps, the chassis has continuity with the guitar strings. If the hot & neutral were reversed it would mean the guitar strings have deadly potential.

To add to what Rick said in that case change the plug to polarized being sure to connect the wire to the chassis to the wide blade.

There are still a few old refrigerators from the '40s and '50s around that are the same way.
