    Running electrical service to outdoor hot tub
    I have all of the necessary wiring for hookup. I am placing the gfci disconnect on outside of the house but I have to run over the existing patio to tub which is approx. 8-12 ft. Can I run #6 thhn wiring in grey plastic tubing and have it exposed (I don't know any other way without busting up the concrete?

    Your plan:

    Will be fine.

    Be sure the THHN is also rated THWN, for wet locations, which is outdoors.

    Be sure to use at least a #10 THHN/THWN green insulated conductor for the equipment ground, along with the three #6 conductors.
