If you are dealing with single phase 120 volts - yes. If you are dealing with 220 volts - no. You need at least 3 conductors for 220v - 2 hots and a neutral. It sounds like you are using this for the heater which might need 220v. Don't forget to run a bond wire (ground) "continuously" thru all your equipment also.

There needs to be gfi protection for the spa but it does not need be in the disconnect. You have to have the disconnect near the spa but the gfci can be in the electrical panel as either a gfci protected panel or just the breaker for the spa. As for the amp requirements you stated yes you can use a 50a gfci breaker as long as you have a 50a or smaller fuse set/ over-current device in the disconnect. The 60a disconnect is merely the maximum amount of current that the device can safely be used for. As for the 6/2 wire yes it can be used as long as there is a grounding wire and the spa only requires 240v. If the spa has lights or a radio it may require a neutral (6/3) to facilitate a 120v circuit for the lighting and 240v for the heater/ pump. Also make sure that the wire is rated for wet locations ie. THWN #6 AWG. whether it is in conduit or not it is a code requirement.

Don't you mean a 6/3 wire? That is what I have for my spa. As far as I know the disconnect needs to be nearer to the tub. Mine i about 2 feet away and at the side of the tub that opens for maint.

I'm posing a statement to the other answers.
You can make 220 work with 2 hot wires and no neutral, reason alternating current, each leg is neutral half the cycle.
I never said this is code but it worked in the old days.
Now the ? was about a GFCI requires 4 wires Red, Black ,hots
White neutral, Bare or Green equipment ground, also called the redundate ground.

A spa is too important for this too be a do it yourself job,
You may save a bit of money and electrocute someone.
Pay the money, get a permit and an electrician. Safety rules can be different for spas.
Where I live the Green ground wire has to be bigger than the 220V power wires and it cannot be broken between the spa-pak and the fuse box. By unbroken, this means one peice, not joined to another wire.
Get a permit and an electrician.
