Wiring a hot tub

[Paul.M]

What is the Kw ratting of the hot tub?

 

[RyanPaul]

pound to a pinch of salt they will want sockets up there once they realise that hot tubs will come with music, fridge for drinks, perhaps a heater etc.

They already have power to the garden it's just not sufficient for the tub

 

[RyanPaul]

THe tub is 3Kw

 

[RyanPaul]

Just to add the tub from the shed is going to be 6 meters

 

[Paul.M]

THe tub is 3Kw

3 Kw = 13A + a couple of lights!!!!


Install a none rcd DB in the house, run 4mm SWA from it to the hot tub protected by a 20A MCB. IP ratted CU at the hot tub with 30mA RCD, 16A MCB for the hot tub & 6A MCB for the lights, job done.

The hot tub is 32 amps, the heater is 3Kw, it has 85 jets and water line spot lights, the pumps are 2x 2HP and 1x 3HP.

the supplier demands its RCD protected and demands a rotary switch as that's where they will connect their wires up.

 

[Paul.M]

ok let me rephrase the question.

What is the total load of the hot tub? Once we know this we/you can work out what size cable is needed and what size OPCD to install.

 

[RyanPaul]

Honestly I couldn't tell you this is all the information I can get from the suppliers website. AquaMax Atlantic 85 Jet 6 Person Hot Tub

 

[RyanPaul]

Circ pump 750watts
air pump 700 watts

3Kw heater

1x 3 HP pump
2x 2 HP pump

That is all I can find on it,

thanks for The pacience Paul

It is advertised at 32A. Google the tech sheet for this model and take it from there. If not just use 6mm 3 core swa and install it as above.

Looks like the distribution circuit will require RCD earth fault protection unless the Zs is low enough (unlikely).

I would suggest the whole job is reconcidered myself after the latest info from the OP.
