Good point Gary. I assumed that if the wire were 14 gauge the breaker would be 15 Amp. If a real electrician originally installed the circuit it would be a 15 AMP breaker, 14 Gauge Wire and a 15 AMP outlet. Many times home owners have a 20 AMP plug and simply change the outlet. Most appliances that have a 20 AMP plug dont really pull the full 20 AMPs and you may be able to get away using a 20 AMP plug on a 15 AMP circuit.
The point of our advise is to inspect the outlet and fix if necessary. Hopefully it is a 12 gauge wire and 20 amp breaker. Just make sure it is.
