hot tub in garage (diversity)

[scott 123]

house supply 100A tns 32A mcb feeding garage(10mm swa buried ) 100A board.. currently with lights on 6A and sockets on 20A ....customer wants massive hottub installed in garage ....problem is manual says requires 2 x 32 A supply for tub ........any suggestions ?

Do you have a picture? 2 x 32amp might mean L&N conductors to the unit.

If it is only 32amp, upgrade the MCB size to the garage ( if possible, assessing conditions )

Then you can run the original stuff + Hottub

My suggestion is that their electricity bill will be huge!

It's hard to tell what is actually being said in the instructions. 2 separate cables or 2 separates cores? Are you an electrician?
I wouldn't imagine the thing needs 2 x 32amp supply. It's only a couple of pumps and a heating element.

If it does need 2x32a supplies then they'll have to cough for a bigger sub to the garage or get a smaller hot tub that fits with the present supply. There's no alternatives.

But OP said 'massive' hot tub......could have 2x 6kw elements.
I think we need kw rating from the OP.

True.... let's see the technical info OP. I am curious now.

Do you recall the make?
Most big ones are 32A, but there is the Michael Phelps model at 42A

Don't do what I did yesterday and put it on a 6amp mcb by mistake! Should have gone to spec savers!

I have come across a hot tub with 2 supplies needed, was in garden of a scrap metal dealer who fancied himself as a bit of a local celeb living the big life. It needed 2 cables, cant remember what rating MCB but each cable did different things, one supply cable was the heating system and the other did pumps, sound and lights... the hot tub was like a mini swimming pool and could take several large adults or in his case young ladies charging by the hour! only learned this as he wanted sockets down by his BBQ area and had to work out why the hot tub had two supplies in the consumer unit for outdoors as it confused me and then boss no ends. I still do not see point of underwater speakers!

Just a thought on the op's post is that the hot tub could be a foreign model thats been imported as a lot of the US models are designed for multiple wires and often have 2 lives one neutral and one earth, its less likely on Uk models unless very large with separate spa/hot tub compartments within the hot tub as in my example.

Yep,that preliminary spec,sounds very American,and can usually be translated back in to our reference language,and a decision made.

USA alleged 240 gear - only insulated to 120v !

Inverted 120V phases (or similar, whatever correct terms are)
120-0-120 where 0 = Neutral

£13K plus an enormous electricity bill - must have some cash your customer.

 

[Wilko]

Yikes !
With 14hp of pumps and about 8kW of heating I can hear the polar bears crying already ...

Money doesn't buy class, maybe style but defo not class.

That thing is huge!! And it weighs 1.5tons, they will need a massive slab for that as well

Money just enhances you lack of style and taste come to that hence the hideous hot tub.

What a load of codswallop, just to make your knob go all wrinkly. And here's the EU banning vacuum cleaners!!!!!

I'm thinking service connector block, a 63A sw fuse, 10 or 16mm swa depending on installation method and distance. Just to try to minimise house lights dimming when warp drive is engaged.

 

[westward10]

I would tell them to better spend the money on a taste and style refining course they will then realise said hot tub and current lifestyle adornments need addressing.

 

[Dave OCD]

And you wouldn't be getting any more work there, ever.

It will come with 2 fly leads each with a 13A plug fitted. Double socket should do it.
