I agree. I'm not trying to cut corners, just dealing with primary panel
breaker space and cost of new 60 amp GFCI.

'66. One cold water ground. More than 8 feet away. I think Bud and RBM
answered my question. I'm at least going to buy a new 30 amp 2-pole GFCI
and probably a new 60 and replace other two at load center. Another reason
I want to go with a new 30 amp is this spa (used) came with this
configuration factory.
Thanks for your input.
