it is not wired 220. It could be wired for 240 . you really need to look at the nameplate rating.

110/220


208/230 means any voltage from 208 (a common commercial/industrial voltage) to 230 (the common household voltage).

These voltages are plus or minus 10%, so the actual operating voltage can be anywhere from 187 to 253.

In your case, you'd use a two pole 15 amp breaker. Not more than a 15.

If you're using NM cable (Romex), a 14/2 will work just fine up to around 100'. If it's longer, use a 12/2.

Mark the white on both ends near the terminations with colored tape (any color other than gray, white or green will do, most of us use red), or color it with a felt-tipped marking pen.

Just curious, and this is a serious question: If the name plate says 230V, why would you think it would be wired for 120V (110)?

Maybe the 208 volts on the nameplate confused the OP.
