hot tub supply...

[Welshsparky]

Wired a hot tub in 6 months back ... 6mm cable to isolator from db , from isolator to hot tub. the hot tub is only pulling 16 ap but id put a 6mm in asthe customer said they may upgrade in the future.

just had a phone call from the customer to say their is a funny smell from isolator, customer opened isolator and their hasbeen a blow off some sort, RCD did not trip

Any ideas why this would happen?

All connections were as tight as can be and all relevant tests were carried out upon completion

Sounds about right!! lol!! You sure that low setting isn't for turning the water over (through the filter) during non use times, eg maintenance only position??

Lol yep !

Nope there's also an Eco mod for when leaving the hot tub over winter

Drops temp to 12 degrees and runs pumps 24/7

With low current mode on the heater doesn't come on at the same time as the high speed pump

On 32a mode everything can run at once

Sod that, cheaper and easier to empty and mothball the dam thing over winter!! lol!!

winter is the best time to use a hot tub!

Rather you than me, if were talking about in the UK!! You'd need pretty deep pockets to keep one at 12c during the winter months, let alone bringing the water temperature up to working levels and maintaining that level during use!! lol!!

I'll agree with you, if were talking about somewhere around the Med though. lol!!

Are you 100% sure it's only 16A? Seems quite low.

The only hot tub I've had any experience with was a Legacy branded one and that was rated at 50A, but it was nothing special, just your standard 6 seater.

Agree, I wired up a similar tub myself and it needed a 16mm2 cable on a 50 amp breaker down to it in the garden from the house, I assume yours is a small bath tub type then and not a garden 6 seater if only 16 amp?

nah, in the uk! no better feeling than being a nice hot tub with a cold beer on a winters day

If you can afford to heat the hot tub!! :wink5:

Course I can. helps when you tap into next doors supply...

Nope, ours is a full size 7 seater tub

On 13a or 32a supply

Can be run off a plug top if required lol

We're used to the bills

My koi pond (2,500 gallons) is heated to 12 degrees in the winter with a 6kw electric heater !!

That costs a bit !!! Lol

Our spa stays hot for at least 3 days without the electric on ! Well insulated
