I hope that US 220V outlets do not use the same pinout as 110V.

	110V			110V + Ground (which pin is active?)

AFAIK the US 220V is 2 phase 110V and used for stoves etc.

Here in Australia we have 3 phase 240V giving 415V between each active.
For 240V we have crowfoot sockets:

	A	N
	/	\


	    |E

10 Amp outlets are as above, 15 Amp have a wider ground pin while
20 Amp have all three pins wider. This way you can plug 10 Amp plug
into all three outlets, 15 into 15 or 20 and 20 only into 20A sockets.

I cannot recall seeing a 415V socket - it would need 4 pins (3 active,
1 ground).


This is probably getting a bit far off topic, at least for the subject line.
