I just purchased an Edison hot tub and am in the process of wiring it. In the control box, there are only 2 termination lugs for each 120v source and a bonding lug. Where does the neutral terminate?is it strictly a 240v tub? do I abandon the neutral at the control box and the GFI load centre? If so, how does the GFI operate with no reference to the neutral as it is isolated in the load centre? If this is a 240v set-up, why would your staff tell me to use a 6/3 conductor?
