Adding a spa disconnect sub-panel

[pieceofwork]

I'm in the process of installing a sub-panel disconnect for a hot tub. I will be running #6/3 w/ ground from my 200a main service panel (located in my garage) to the sub-panel disconnect (located outside the garage). I will install a 50a breaker inside the 200a main service panel for the feed to the sub-panel disconnect. Total distance of this run is approximately 20 feet. The sub-panel disconnect will house a 50a GFCI breaker which will feed the control panel of the hot tub. The sub-panel disconnect is an Eaton CH4L125RP rated for 125 amps and up to 4 circuits. The hot tub requires a dedicated 50amp circuit with GFCI. The tub I'm buying is used (a year old) and I'm taking the sub-panel and all of the wiring. So far this is pretty straight forward. But...I'm considering adding an outdoor outlet fed by this sub-panel disconnect for which I will use a 120v 15a GCFI breaker.
So, here is my question - If I add a 15a 120v circuit for an outdoor outlet fed from the sub-panel disconnect, can I use still use a 50a breaker in the 200a main service panel or does it have to be a larger breaker?
Thanks!

I have your setup, 50 amp GFCI and a 20 amp GFCI convenience receptacle fed from a 50 amp breaker in the main panel, with no problems with either. The manual for my tub calls for a 50 amp, but there are only two or three conditions that would pull more than 40 amps at one time.

Keep in mind the breaker only protects the wiring. So that is what needs to be up to snuff and match the breaker.

Awesome, thanks!

Yes, the sub-panel with 50a GFCI is the disconnect. Code calls for the disconnect to be located no more than 5' and no further than 10' away.
