The GFCI disconnect needs to be at least 10' from the inside rim of the spa. National code does not enforce a maximum distance, but it must be on the same grade and usually within line-of-sight of the tub. Many local jurisdictions also enforce a maximum distance.

Yes. Liquidtight flex is only allowed for the last 6' of connection to the tub, which means that you need to use at least several feet of rigid conduit out of the disconnect before the transition to flex at the tub.

A spa is a rather complicated hookup, do you have the rest of the circuit up to code such as insulated grounding?

AS far as grounding I think I've got it.Installed a 100 amp sub box in the basement with the neutral buss isolated (with your help).The spa uses 50 amp breaker so I am running #6 for my 3 wires and a #10 for ground thru steel conduit to GIF.I have a sheet from the spa manufaturer about the hook up from the GIF to thier spa box.If I have anything wrong or you have any cautions for me I would be glad to hear them.
Also when I make that transition from ridged conduit to flex-steel conduit would you do that under the deck or run the steel aong the wall then run say 3 feet of flex accross the floor.It would be in a non traffic area.Thank you again.

I always go under the deck right up to the spa, then put a female threaded fitting on the rigid conduit. Rigid PVC or rigid metal is okay, but I would almost always use PVC in a residential setting. I then put a male threaded fitting on the liquidtight and screw the two conduits together then snake the liquidtight up into the spa wiring compartment from below so that no wiring is visible on the deck. It helps to pull the wires through the conduit and flex before you snake it into the tub, because the "S" curve that you need to make to get into the wiring compartment is usually a little tough to pull through.
