Welcome to our forum.
Well it's the beginning of August and our tub is expected in about a week or so, and this morning the electric work was done. We called the same guy who built our house to do it because he's an honest man and has become a friend of ours over these past 10 years. He had to install a 60 amp breaker in the basement box and run the wire about 30 feet across the ceiling to where the outside GFI box for the tub would be. After that he ran 35 feet of wire through underground conduit to the tub location, leaving 10 feet at the end for adjusting the location. Altogether for 80 feet of wire, the outside GFI box (50 amp), the inside 60 amp breaker, conduit, and labor for the trenching and electrical work he charged $381.00. I will come back to post when the tub arrives.
Taylor makes great test kits for pools and spas where you can accurately track all important parms. I have a model 2106 (bromine).
