I got a question today about connecting a hot tub. I have done tubs and pools before, long ago, and felt comfortable enough with my experience to listen. He has the instructions for connecting the spa to a three wire service. There are instructions for four wire that are applied to other models but this is supposed to be three wire.
Connecting to a 60 amp, 240 volt GFCI breaker. Connected load is 47 amps. He says there is no place to connect a neutral wire so I say all loads must be 240 volt. There is one buss to connect all grounding conductors at the spa. Instructions state that a ground rod will be driven and the grounding buss will be connected to that rod. No mention of a EGC or anything that sounded like a grounding wire back to the panel. The recommended wire size for this load is #10cu.
I asked which country? Instructions show USA.
I didn't have anything nice to say about this project and think something is really out of whack somewhere. Has anyone seen Spa instructions that go along these lines? I have not had the instructions in my hands to see if the information was relayed correctly.
I will be forwarding your comments.
