I put in lower-rated receptacle, now what?

I recently replaced an electric laundry unit located in a closet off a dinette. The old receptacle was 240V 30-amp in a two-gang box. The new machine is 240V, rated at 10 amps, and requires a 6-15R receptacle, which I put in.

There are four wires coming into the box. I hooked up the two hots and ground, put a wire nut and tape on the neutral, and am in business.

Would like to know what to do next? Do I need to replace the breaker with a smaller one? One thing I've considered is putting another 6-15R in the box and connecting it with a pigtail.

Thanks.

New Receptacle

What gauge wire is in the circuit? What is the amperage rating of the old breaker?

Since it is a 15 amp plug use a 15 amp breaker.

Why? Generally on a 240v circuit it is one receptacle per branch circuit. Second breaker rating shouldn't exceed receptacle rating.

Also general use circuits are limited to a 20 amp maximum. Adding another receptacle would not change this.

OK, I'll put in the 15-amp breaker. 240V outlets are useful and I had hoped to get another one out of this since there is plenty of room in the box and 10-gauge wiring going to it.
