Hi, I've just had a cable put in for a hot tub. The electrician used 4mm armoured cable approx 20m from consumer unit to 32amp switch outside. The hot tub company states they require a 32 amp isolator switch with a (6mm) swa cable to go to the hot tub but the electrician says 4mm will be ok. From what I have crudely worked out the maximum the tub will be drawing is 26/27 amps. Does this mean 4mm is ok. I have contacted hot tub company and they say 4mm is ok if the electrician says it is. So why would they stipulate on their website. Just need to someone to put my mind at ease thanks.
