advice on fuse for a sunbed in the home pls ?

:D hellooooo everyone
I am looking for some advice about installing a stand up sunbed at home , I stupidly bought a commercial sunbed to use in my home and now need advice on what amp fuse and which wire to use for safe installation .
its a 48 200w tube sunbed , would it be safe to run it on a 45 or 50 amp fuse with 10mm wire ?? :D
thanks for looking , any advice gratefully received :D:D:D:D:D:D
 
It'll be cheaper to fly to Spain a few times a year than running that monster, ....let alone the initial cost of the thing!! ...lol!!!
 
havent asked a spark yet , cant get in touch with him til next week as hes on holiday
well the initial cost is done lol now the installation cost to sort out !
 
at 9.6kw i would think a 45A trip with 10mm T+E would be ok and a 45A double pole isolator.
 
i would advise getting rid. youwill then not have to take out a mortgage to pay your leccy bill, or for the skin cancer treatment, chemotherapy, and wig that you will surely need if you use the monster.
 
48 X 200W = 9600W (9.6kW).
9600W/ 230V=41.7A (this is the design load/current Ib).
You must satisfy the equation Ib<In<Iz.
In being the protective device (fuse).
Iz being the lowest current carrying capacity of the conductor (this can be affected by the installation method, the conductor length and whether it is bunched with any other cables).
So with Ib being 41.7A, and the fuse being 45A or 50A, the first two parts of the equation are satisfied, all you have left to determine is the conductor carrying capacity.
10mm² T&E has a current carrying capacity of between 32A and 64A depending on installation method. 32A being where the cable is completely surrounded by thermal insulation, and 64A where the cable is fixed to a flat surface and open to the air.
Obviously we don't know the installation method, so we can't really determine the cable size.
 
thats not the advice i was after and as an adult i know the risks thanks ! i have had one b4 and they use £1 a time so its hardly breaking the bank is it !

If the cable is covered with thermal insulation at a depth less than 100mm anywhere along it's run the current rating would be acceptable for a 45A fuse, if there is no thermal insulation covering the cable, then you could use the 50A fuse.

You may of had a Sun Bed before Amanda, but that one had a 13A plug top on it. ...It certainly wasn't a commercial 9.6KW/42A monster you have now. I think it's going to cost you a little more than a pound a go this time... Power wise, your now into the realms of instantaneous shower heaters....lol!!

If you round it off to the nearest Kw say 10 Kw and multiply that by the unit cost of electricity you pay then that will give you how much it will cost per hour , personally i would use a sub board for it 63amp RCD 45amp mcb , 10mm cable 45 amp switch as you would a shower obviousley as has been said it depends on the installation methods used also ensure your spark gives you a certificate and notifies as well as this is a notifiable job

As we have given you some info on this , please please please do not attempt to carry out this work yourself , or the friend who knows a bit about electricity , you are looking at seriouse currents here 42 amps and 50ma will kill you ,this must be installed by a professional regestered electrician
Amanda im not having a go there are just to many people getting killed recently

It just keeps reminding me of the film Final Destination 3
View attachment 5650

Anyway.... Slap my wrist for going off topic
 
i connected a couple over the years-is there no nameplate on it

i'd say you may need to add on a bit on top of the 48*200w tubes

-maybe 20% or so to get your final design current

hard to say

thanks for your concern , will see the electrician when he comes off his hols . hope hes in a good mood and goes easy on the price !!! lol
 
amanda. apologies for my facetious answer yesterday. was just in 1 of those moods.
 
Have installed a couple of those monsters, and all I would say is follow the manufacturers instructions. You will probably find it needs a 'C Curve' MCB and possibly a time delay RCD due to the start up current and raised earth leakage at this point.

Most of these only run for 3 mins at a time, but beware of running for extended periods of time as it wil warm up your supply cupboard (e.g. girlie tanning [frying] nights).

Personally I would split the incomming supply and fit a dedicated CU for the sunbed, your own sparky will advise, definately not a DIY option on this.
 
there wont be any girlie tanning nights its for my use only !! lol , how do these tanning shops go on that have 8 beds running at once !!! nightmare ! :p

think you may well have found out amanda we have very odd sence of humors here , oh thats me

shame on you RJW lol

yeah ;) u guys still rock though !!!

so any ideas on the cost ? and would it include materials or do i need to buy them myself :cool:
 
Thats the 'how long is a piece of string' question. It all depends on where you are, cost of kit, cost of any remedial work that might be needed on the existing system (earthing etc) and the route the cables will have to take, and how neat you want the finished job. Only the sparky visiting and quoting will be able to give you an answer. However you will be able to ask the right questions based on the info you have in this thread....

Oh and always let your sparky buy the bits. He/she will be happier knowing they bought the kit they like to work with, plus they will know its up to standard and not flea-bay replicas.

Happy tanning..........

Wait for the long sigh and tsk..tsk...tsk, think of a number between 10-15 and multiply that by 13 oh and dont forget the VAT!
Only kidding:o Just make sure they are qualified first,check their credentials and heed Graeme's advice

I find organic string such as sisal, works better than this new fangled nylon stuff.
