We are installing a hot tub on our deck and need a little advice. We ran a 6/3 wg sheathed electrical cable cable across the basement and out thru the wall above the deck. At this point do we need a service disconnect, and then run a wire from the disconnect to the hot tub? What kind of disconnect would you recommend? Also, the wire will be running under the deck and will be in damp conditions at times. Is UF wire available in 6/3 or do we need to run conduit into the tub? Thanks for your help!
