Can someone confirm for me my wiring in the GFI is correct or not. My GFI trips sometimes immediately or at times after 10 mins.
Does the Ground and/or neutral positions seem incorrect??

I have tested every component individually and each work fine.
My dad wired this, bless his heart,But I am not sure if it is correct. He gave me the tub which he had for 7 years from brand new, which he wired originally with no issue.
Also, I have been shocked once from the water.
Please see the attached photo..

Paul,
The statement of being shocked by this machine and its install, makes these forums useless.
You need a licensed Bonded Electrician to inspect the install and wiring.
There should never be a situation in the norm, where you feel current with a GFCI.
Period.
Do not go any further without either addressing the install, or removing the spa altogether.

*NOTE TURN OFF YOUR BRAKER BEFORE YOU DO ANY OF THIS*

I would say then something is not right and you have a ground fault issue with your wire or equipment.

I can not help you more unless you can show me photos of the braker panel with the cover off shut down your main power just in case your not aware of whats under it. also show me photos of your control box in your tub with the cover off so i can see how its wired, and show me better pics of the gfci and or under the gfci its self. cause when the gfci is screwed into the box it is in , sometimes its hard to see what your looking for and I need the photos of this to make sure things look like they are wired right. If the tub never has a issue with shocking befor it was moved to your home/re-installed then it is a good indicator it is not hooked up right or something happend during the move.

If you can get me more detailed photos of what i asked for I will do my best to help you sir.
