6kw sauna sharing cooker supply is it even a possibility??

[MickSmith5824]

Right this maybe a completely stupid idea....but, guy wants a 6kw pre built sauna in back garden. The fuseboard million miles to back of house so wiring new circuit would be a nightmare. But he does have a cooker supply right near back door of garden. I know it's deemed good practice to have cooker and sauna on own dedicated circuits but if come from cooker switch with adequate sized cable out to rotary switch for sauna and they was never used at same time could this not be a possibility? I have also heard mentioned before that in scenario like this a change over switch might be able to be used? And this would prevent both being used at same time. Could someone explain to me how this would work and how it would be installed. Thanks

So the customer spends probably thousands on a hot tub and then wants to skimp on a few hundred quid to get power out to it, LOL!

Seems about standard ?

more like the op thinking I will try a cheat a bit by don't put a new circuit in. By asking us is it acceptable.
Knowing that tha facked it should be done correct. My ten pounds worth.

Unreal some of the ideas people have.
Don't turn both on at once ? What sort of cowboy lunacy is that ?

The OP has not given any reason it can't be run back to the CU. First stated it's a million miles away then only 10m.

Is this a wind up thread ?

What the OP proposes is possible but totally impractical because sooner or later the client will want both appliances energised at once. I suspect he isn't overly experienced and the thought of installing a new supply over a million miles or ten metres is daunting. If he does it this way in a few years he will look back and think why on earth did I do that.
He hasn't been on since he posted so may be we will never know.

Do you know if there is much difference between the 18th and the 17th editions? Just found a used 17th edition on eBay for £8.00.

 

[westward10]

The difference is the 17th Ed is no longer a current standard.

Most of the 17th edition is carried on into the 18th, but for any new installation you would be judged solely on the 18th edition requirements.

That situation is factored into the max load and diversity calcs so it shouldn't be a problem so long as the results of those calculations are adhered to and catered for. Both devices are thermostatically controlled so the principle is that the situation you describe is unlikely to persist for any great length of time. For the duration of that condition the installation should be able to take it.

The 18th standard is the 17th standard plus mods and extras. It's not a complete rewrite. My question was in relation to the mods and extras.

I don't know if there is the equivalent of the Amendments to shows changed 17th to 18th, but I suspect not as the IET would risk losing sales that way!

The 18th has that sort of thing covered in the foreword and shows change bars on the pages so folk familiar with earlier versions can see if things have been updated, which is the opposite of what you want!

I was watching John Ward on his YouTube channel a while ago and I think he suggested that you can find the differences summarised somewhere on the internet. Are you aware of this? He was talking about the differences between the 17th and the previous edition.
I 'll see if I can find it.

My point was if you fit a change over switch it is not possible to have them both on at the same time.

Ahh. Ok. That's different to how I interpreted yoru comment.

My BYB has arrived. £8.00!! To be honest I was expecting it to be raggedy and covered in cr@p. But it is barely used and like new. Well chuffed.

Dedicated circuit, there is no other solution IMO.

Some might say if a jobs worth doing, its worth doing wrong with a nail to short and a screw to long Cowboys. ha ha (who remembers that TV series in the 70's)

Used to love that as a kid. Watched one the other day on YouTube, and let's just say it haven't aged as well as some sitcoms!
