I'm not the electrician but I believe it is a circuit with a 12 gauge wire for a 20 amp plus the appropriate breaker and also a 20amp receptacle/plug. A 15 amp circuit will have a thinner wire like a 14 gauge.
When I did my house I had new wiring pulled and a new breaker just for the 20amp circuit and I installed shunyata outlets rated for 20 amp circuits.
In terms of the explanation, google 20 amp circuit and see what you get.
