I am wiring a Spa. I plan on doing the work/wire running my self and having and electrician do the final hookup.
Location = Shasta County CA.
This is the project.
Spa needs 60Amp service (spa panel states 48 Amps - has 3 motors).
I have a 200 amp service with open breaker locations. I have 60 amp breaker (NOT GFCI - same brand as panel) for main box. (GFCI will be explained later.)
I have some THHN left over from other job (Sub panel in pump House = Romex (or similar) in house, to box then THHN into conduit Underground to Sub panel) #6 THHN wire (Red, Black, White, Green).
Can i use THHN wire in the garage walls without putting it into conduit or is THHN wire only for conduit? Can i use THHN wire in the attic space or does it have to be in conduit?
I have 60 amp Spa GFCI box (plan to put ~15 feet (walking distance) from Spa). I was told that this is recommended to avoid trips due to "long" runs. Also i got SPA box for good price. Note GFCI = code and must be atleast 10 feet from spa (walking distance).
I have disconnect (required by local code) that will be 5-10 feet from Spa.
Total wire run = less than 50 feet.
Can i use the THHN that i have or do i need romex (or similar) in the walls and attic space?
Can i run THHN in the walls but attic space has to also be in conduit? If that is the case can it go directly into conduit (pvc or that flex blue stuff) or does it have to be in a box first?
My current plan = starting at main pannel, 4 wires (red, black, white, green) 60 amp breaker into wall, thru header, thru attic space, into 3/4 pvc conduit, into GFCI box. Then 3 wire (red, black, green)(as spa is 2005 Maxx 705 and is 3 wire setup) into pvc 3/4 conduit, back into attic (out of conduit) thru attic, into 3/4 pvc conduit into 60A disconnect, Then back into 3/4 pvc back into attic (out of conduit), down wall into Box (no wire cutting here) into 3/4 liquid tight conduit to Spa.
Or do i need to get romex (or smilar) for in the walls and attic space. Also would i still use #6 romex and can it be in the 3/4 pvc conduit?
As i said previously. I have #6 THHN wire (red black, White & Green) already from previous job (bought rolls for cost savings). Thus i would like to use if i can.
Any other advise?

I plan on getting it inspected by county.
I was told by spa place & inspector that the quick disconnect has to be at least 5 feet and no greater than 10 feet. I was also told that the GFCI must be at least 10 feet way from spa. Thus i can NOT use the GFCI breaker as the disconnect.
I am now planning to do romex (#4 w/ 8 solid ground or #6 w/ 10 solid ground) from panel to GFCI then same from GFCI to Disconnect, then same to Box at side of house where i will have a splice and transfer to Liquid tight conduit and 4-#6 THHN/THWN to Spa.
Is the #10 ground wire ok, Is the # 10 ground wire ok or do i need to look for 6/4 (where all 4 wires are at least #6)?
Should i spend extra $ and up size wire to #4?

Regarding GFCI - I was told by spa place, electrician & inspector that i need a GFCI even for a 3 wire spa. According to the GFCI (Midwest with GE breaker) I bought it will still work with 2 hots and a ground (no neutral).
I will check the spa when it is wired to make sure that it is 3 or 4 wire. I will have all 4 wires run to the spa just incase (or if i ever change it out.)

I opened spa and confirmed that it is only a 3 wire system. This "240 V 3 wire system" is in bold text on the electrical box and inside the box the terminal is clearly marked (Red 120V /Black 120V /Green Ground). Everything goes thru the computer boards and the lights are 12V. Also the spa was previously wired the same way previously (i know that does not really matter).
