I'm confused by this? What bknifefight suggested works perfectly fine.... the 30a main breaker protects against over current draw and the gfci protects against ground faults.... yes the wires in the wall up to the spa panel have no gf protection but its not needed.... And from what the spa inspector told me the gf I works better if its wired near the load source anyway... which is one of the reasons spa panels are required to be within 10 ft of the spa ( at least were I live) plus its easier to kill the power in an emergency situation.
Its exactly what I did.
I was also told 8/3 wire (which has four wires including the ground) is fine for up to 50a.... my hot tub needs 60a so I ran four separate 6 gauge wires.

A pump doesn't need GFCI protection, does it?

If it is electric and near water a GFCI is a very good idea.

I don't see how it could hurt other than a GFCI outlet costs a few more bucks. I'm also pretty sure that, according to code, any outlet in a garage or unfinished basement needs to be GFCI protected (at least in my state/county). Not that I'm overly concerned with the code. Now I have heard people say not to put a GFCI on a sump pump in case the outlet trips without you knowing and then all of a sudden your basement is flooded.

But the alternative could be stepping into an electrically charged flooded basement if the pump really did fail and develop an electrical leak right?
I had heater fail in my fish tank once and it gave my a nice jolt but didn't kill the fish because the water wasn't grounded... I say use the gf I for brew pumps... you never know.
