hi all . i was just wondering the usall Kw of a hot tub. and what way you would all install it. eg. Cu in to a islotor close to the hot tub in SWA and then flex from there??? all help would be great thanks
Similar to IQ but have used SWA from rotary isolator to hot tub (and no rod).
Thanks, a good one to remember!Be careful here as most, if not all manufacturers insructions specify an additional earth rod for the hot tub itself due to the PD that can exist between the tub and true earth.
Certainly don't recall anything to do with installing an earth rod, but I can understand the logic behind it. I did install current leakage protection (RCBO supplying the feed).I've had a read through a few instructions and it appears most are still to an american standard, they say to bond any metal work or pipework within 1.5m of the tub, to the main earth terminal on the tub and to protect with an RCD, don't shoot the messenger just what i've read.
And some kits even come with the earth rod supplied.
Got to love the harmonious industry standards we have.....such a pleasure to work with.
Agreed they leave it up to your professional judgment with an ambiguous instruction manual thats out of date by years or to a different standard then do you when something goes ---'s up.
