Sauna Heater Help! - What Cable

[Weezy]

As short as possible.
My customer has brought a sauna heater that’s made in the USA the manual is VERY poor, it states that the cable to the heater should be ‘REVE or equivalent’
I took the manual to Edmundsons Electircal wholesalers and they had no clue what that was...

Ed’s said they would look into it, not heard back from them.

I emailed the manufacture in USA, not heard back from them.

Iv done some research and i believe sauna heaters normally range from 75 degree’s to 98 degree’s.

Ordinary pvc t&e cannot be used Swa cannot be used.
Iv read that you can buy H07rn-f cable but this is only rated to 85degrees. So surely this won’t do?

I also read some electricians use HTF cable? i also asked Ed’s for any of this which he also had no idea on...

I did think of using Butyl cable but i’m not 100% sure what it’s current rating is? ideally i need 6mm but it seems almost impossible to buy, they do sell 4mm but is 4mm butyl rated at 32amps like normal T&E pvc/pvc 4mm?

So i’m totally at a lost end, part of me is thinking will the temps ever reach 98 degrees, what do i do?

p.s I really don’t want to use pyro...

Is the sauna capable of running on the changed frequency and voltage?
Any chance if taking a pic of the manual and posting it up.

That looks good, but from the wording i’m slightly confused, is that stuff ‘H07rn-f’ or is it ‘Htf3’ or are they the same thing? because i asked Ed’s for some Htf3 and the bloke said he had never heard of that before?

Has the sauna come with its own small length of cable?
I have wired saunas in H07 and HTC.
The last one I installed was in 5 core H07 (3 phase)
All the cabling was concealed within the timber seating and the base of the sauna was also concealed within the seating structure..
Section 703 is useful for further guidance..
Have you got make and models..
Frequency isn’t an issue but the voltage will be if it hasn’t been manufactured for sale in the UK..
Many saunas have voltage selectors fitted

You will be very lucky to get useful unbiased advice from a wholesalers..
We are the experts and they need us to specify the relevant information..
If you want like for like comparisons of cables from different countries then you need to got the manufacturers or to basec for that expertise

think you'll find that 75 - 98 deg. is fahrenheit. 98. C would boil your blood.

 

[Taylortwocities]

Aye, it’s a US product and they are still in Fahrenheit.

When you order the connecting cable, don’t forget to order it in feet and inches.

or fathoms.

Those temperatures actually are oC
Just don’t stay in them for too long

I don't believe the inside of a sauna will ever reach 98C!

 

[freddo]

Sauna temperatures are generally between 70 and 100°C (158 and 212°F).

Within the sauna? Never knew that - seems a tad high.

 

[freddo]

Had to do some repairs in a Hotel sauna a while back, it's not fun working in 85C heat.

Within the sauna? Never knew that - seems a tad high.

Some will go to 140 - 160 deg C for brief periods of time.

There's a real stupid competition in a country (can't remember off hand) that people compete to see how long they can stay inside for.

I want to say it's a Scandinavian country. Seem to remember reading about it as they were considering banning it after a competitor died.
