[ARC5] 125 VAC Line? Make Your BA's Happy,

[mstangelo at comcast.net]

Look at the NEMA 1-15 plug. Lot's of pins have holes in them. What is the purpose of those holes?

Are there dimples in the female receptacles for the holes?

Yes, I know the old joke - the current flows through the holes :-)

    This discussion got me curious. I found:

http://www.worldstandards.eu/electricity/plugs-and-sockets/

    There is a pretty good history at:

https://en.wikipedia.org/wiki/AC_power_plugs_and_sockets

     It seems to me the current (no pun intended) sockets in England had 
a shutter which covered the hot terminals when no plug was inserted. The 
grounding prong on the plug pushes this aside. While someone here 
claimed far fewer people got electrocuted by 240V and 120V I think that 
is due to the safety plugs and sockets.
     Actually, it is CURRENT that is important. See:
