Howdy,

Guessing that you have a NEMA 10-50 outlet?  I'm not sure code allows those
any more but ??  You do wire them with the ground not connected.  I'd have
said that modern code would require a 4 prong 14-50 for 220vac connections
where the device also wants 110vac.

My recollection, which may well be wrong, is that the only modern 3 prong
220vac outlets (6-50) are supposed to be wired with the two hots and the
ground... Neutral not connected.  And that those connections are only used
when you have a device that uses only 220vac, not 220vac along with 110vac.

I think it's a lot more common these days for any 220vac connection to use
4 prong outlets.

Mark
