    I'm looking at running a circuit for a hot tub that requires 50amps. My main panel is pretty full but there is a 40amp dedicated circuit that was installed for an electric stove that isn't utilized anymore because it's been switched out to a gas stove. Here's my plan I'd like some feedback.

    Run Length: 75' from main panel to hot tub. 50' of run is from main to spa panel and then from spa panel to spa it's 25'

    Hot Tub Requirement:

    4 wire 50 amp 220v service

    PLAN:

    1. Switch out 40amp breaker in the main panel to a 60amp
    2. Run #6 THHN from main panel 50' out to GFCI hot tub panel with 50amp GFCI breaker
    3. Run #8 from hot tub breaker to hot tub
    4. The whole run is contained in 1" Sch. 80 with all joints glued.

    Not sure if code requires a 120 branch circuit from the spa panel or not.

    Another 75' of #6 isn't that much more expensive, use #6 all the way.

    Yeah I started thinking the same after i posted. It's a total 75' run for everything so i might just buy the 100' THHN rolls.
