Add Receptacle with Breaker

I would like to add a dedicate outlet for high draw items (hairdryer, heater, griddle, etc.) The plan is to a add an inlet and route the wire directly to this one outlet. However, I don't want to solely rely on the breaker on the post.

I saw this in a hotel. I looked at HD, Lowe's and two local electrical distributors with no luck. I would prefer 15A/20A breaker.

Any ideas where to find this? Alternatives?
