OP checking back in.
I do appreciate everyone's comments though I don't totally agree
with firstname.lastname@example.org that "The OP obviously doesn't have the
knowledge to know if any further electrical work will be done
properly". If I were that blissfully ignorant I would have been
sitting in the spa today instead of posting here. Trad, you have been
Anyhow, I've reached a decision not to have the "hack" back.
While taking pictures of his "work" today, I stumbled on the last straw
when I discovered that the shutoff box he installed is just a 60 AMP
switch, not a breaker. Not only is the spa not protected by GFCI it is
not protected period. This is criminally negligent!
I talked to the service department of the store that sold the spa and
they recommended a licensed electrician that's done many previous spa
installations for them. After talking to this new electrician about the
work done, he's in disbelief that a claimed licensed electrician
would be so irresponsible.
So, I'll call the "hack" tomorrow and tell him how it is. I will
have the job done right by someone else because I cannot trust him
again. (Fool me once, shame on you, fool me twice, shame on me.) I'll
give him the opportunity to reimburse me for the work needed to correct
his installation; otherwise I file a formal complaint with the state
licensing board. I should probably do this anyway. I might save some
homes from burning down or some lives from being lost.
