yes you can, if oyu plan on decommissioning the hot tub. if the hot tub will remain operational, i would humbly suggest not pulling any other loads off that circuit. and whay is 4 wire? a 220v ciruit is usually 2 conductors and a ground. a neutral may be included if and appliance, like a hot tub, needs 110v for certain contriols or motors. if yo were wiring a decicated 220v circuit in a shop, assuming the tool being activated has no 110v requirements, the circuit would comprise 2 conductors (both hots) and a ground.

-- there's a solution to every problem.......you just have to be willing to find it.
