Dedicated 15A Outlet
We wanted a dedicated 15A outlet for hairdryer, space heater, etc. I wanted a circuit breaker inside so I would not have to go outside. Parts:

I would be questioning the interrupting capacity of a circuit breaker like that. Residential type breakers (and in pedestals) will have a minimum ampere interrupting capacity (or "AIC" for short) of 10,000 amps by code. Those mini-breakers often only have a rating of 1,000 or maybe 5,000 amps.
With too small an interrupting capacity, under short circuit conditions, the peak amount of current a system can deliver can cause a breaker to explode, catch fire or fail to operate with potentially serious consequences.
If there happens to be enough overall impedance in the circuit between the mini-breaker and the power company's transformer, and you have a short circuit, you *might* be lucky, but if the transformer is nearby, you may not be. And the bigger the utility transformer, the higher the let-through current will be (for ex., pad-mounted transf. serving many users).
The safe and easiest thing to do is just match what's in the pedestal which is going to be a min. 10,000 AIC rating.
