All three pins on the other end of an IEC power cord are flat blades.

You're talking about this IEC (http://de.wikipedia.org/wiki/IEC_60309) power
connector, rated from 16A up to 250A @690VAC? ;-)
But it also uses round pins, not flat ones.



No, silly. He was talking about the STANDARD US 120V IEC cord used on
nearly everything made these days, from dongles to 70" FPDs.

Ah, that's what I reckoned, cords with the *international* standard socket
type IEC 60320-C13 /max. 70°C/10A (and -C15 /max. 120°C/10A or max. 155°C/16A).

And there is also our famous Euro socket for small devices according to
protection class II, the type IEC-60320-C7, which normally is the device sided
end of the 2.5A Euro wall plug we had discussed earlier on.

But they all have in common, that they provide excellent user protection
against touching of live parts *and* they all plug mechanically *into* the
counterpart with their housing, hence guiding mechanically stress away from
the contacts and into the housing.
