advice on fuse for a sunbed in the home pls ?

[amanda30]

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 ??
thanks for looking , any advice gratefully received

What has your spark recommended?

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!!!

 

[amanda30]

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 !

ty spinlondon x it will be installed through the floorboards to the fuse box under the stairs

thanks bert x

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

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
