according to 680-40 for outdoor spas it sends you to 680 parts A and B. 680-12 states that a disconnecting means shall be provided and accessible within sight of all pools, spas, and hot tubs and shall be at least 5 feet from the wall. As for the gfi requirement, in my area a gfci breaker is required but I cant find the article. I dont know if this is a local thing or in the nec. hope this helps.
the disco is something that needs to be within sight of the motor, as some tub motors are not intergral to the tub ( as in commercial settings) an E-stop for the serving motor is to be placed within sight of the tub. (from the hip, this might be 680.41)
isn't it interesting that , a permanent hardwired pool should not require a GFI , where most hot tubs & spas are listed for them?
