my isolator is on the side of the hot tub (in the filter cubard as placed by the manufactorer)
You should be able to always open the filter/controls compartment. Unless its a chinese replica/built heap of **** that you will need to unsrew panels.
And for reference, mine is installed on 10mm cable. Maybe because of the length of cable? Its maybe 30 meters in total. But the cable that is running inside the hot tub (3 meters)is maybe at 35-40c temp as the filters etc are not insulated and it gets very warm in the housing.
