3-wire hot tub
having a hot tub installed...only two lines (black & red) have been strung to back of garage...waiting for sub-panel and tub. my tub people tell me that I need a three-wire feeder (hot-hot-neutral) and my electrical man says that the 'tub' will be grounded by wire to the pipe that ran the wire...what little i do know (nothing) tells me that a 4' rebarb could be drove into the ground next to the tub for my ground...and exactly why is a 'neutral' used for? Distance from main breaker to sub-panel is 75'
Distance from sub-panel to 'tub' will be right under 10'
Distance from sub-panel to 'tub' will be right under 10'

A neutral carries the unbalanced current from tub control circuits and lighting that are 120 volts.
You will NOT drive a rebar or grounding rod at the tub.
You will also need a 120 volt GFI protected receptacle with a weatherproof in use cover. IIRC no closer that 10 foot.
There may be bonding issues depending on your specific circumstances.

Your local code may have an exception which allows the proposed installation.
