Hot Tub on GFIC

I live in Southeastern Virginia. I'm putting a 240V 48amp hot tub on my outside deck. All the mechanical work is done and inspected, now it is time to do the wiring. I currently have a 50amp breaker that serves a pier with two boat lifts (two 3/4 and two 1 hp motors). I not be running the lifts and the hot tub high power motors at the same time. All motors on the pier are wired at 120V and have local GFIC protection. The question I have is if I add the hot tub GFIC to the 50 amp circuit breaker, will it pass inspection? I know that homes have lots more 20 amp outlets than each 20 amp breaker can handle so the breakers blow when overloaded. Can I do the same thing with the 50amp circuit?

Welcome to the forums.

A little bit of a gray area here. Your spa requires a 240v 50A service with an insulated ground. That would mean you would be required to have four wires at the sub panel including the insulated ground wire.

Agreed it's a grey area where you'll need to check with the local inspector.
