My point was that depending on how the IEC is orientated, it could change how a person wired up the live and neutral. ie, if you said "pin closest to the fuse is live" and you did 99 that way and then some flunky installed the IEC upside down you may wire the neutral to the fuse without thinking.
I did a quick search for pics on the web and they all look to have the earth pin at the bottom so my observation is probably crackpot anyway.
I agree that if there is no earth connection, one would probably source two pin connectors for factory product.
Lunchtime!
