Two parallel blades is 120V 15A. One perpendicular to the other is
(usually!) 120V 20A, but it could be a 250V plug, too. The 120V 20A plug
can be adjusted to fit a 15A recep by the judicious(sp?) application of a
pair of pliers... No, I've never done such a dangerous thing! -_^ Just
remember, too close to the body of the plug and it'll shear off, too far out
and it won't insert fully into the plug.
