I didn't check to see if it really was a GFCI I just assumed it was.

As for why its needed, my thought is its an appliance that half sits inside,
half outside and the base is full of water.

You know the whole water and electricity don't mix.

I installed my window air conditioner and the GFCI on the end of the cord
would not reset. I figured I would replace the plug and get an inline GFCI
to replace what was there.

I cut the plug off the end of the cord. As I was doing this I was
wondering how I would figure out which side was black and which was white.
Well I looked at the cut end and to my relief I saw a white, black and a
green conductor inside the sheath, OK a piece of cake.

As I cut back the sheath I found that the white and black wires were
wrapped with a copper shield like the outer conductor in CATV cable.

I was like what was I supposed to do with this shield. I cut it back the
"shield" to keep it away from the terminals, put the plug together plugged
into the GFCI and every thing worked.

So why the "shielding"?
