Cooker point

[Technic]

Hi all,

I am a new member and work as a TV/VCR engineer in the NW but dont have a great deal of experience with household electrics and have one or two questions if anyone can help.

I have just a double socket in the kitchen of the house i am in at the moment which as far as i can gather is connected to an old CU (with wired fuses) with a 15 amp fuse, i want to do away with this and just have a cooker point with a single socket, i know i will have to run some heavier cable the run is about 12M but the fuse is colour coded blue (15 amp), can i just alter the value of the fuse wire or do i have to replace the cartridge to accomadate a higher rating of fuse or is there maybe a better solution?

you would have to change the cable first, to just uprate the fuse not good.

Idealy it would be best if you could get a plug in mcb of the correct rating to your new cooker

For a 12M run with a 10KW cooker what fuse and size cable would you reccomend

provided its not running in thermal insulation 10mm on a 45A

if thermal insulation is involved it should be 16mm

is the old CU a wylex
if no then good f*cking luck finding anything for it anymore
if yes then is the main switch rating 100A
if no then the most that should be fitted is a 32A breaker (larger units are not supposed to fit but the keying system that is meant to stop you is not very effective)
if yes then you can fit a 45A cartridge fuse (plug in mcbs stop at 40A)

also if you use a 45A cartridge fuse then you should use a cooker control unit without socket

p.s. by the deversity rules you would be allowed to put the cooker on a 32A cuircuit but neusesnce tripping is fairly likely

btw you can get a 45A cartidge fuse unit for a wylex standard board here

Plug

you can get stuff for Wylex standard range at WF easy.

what is WF?

 

[securespark]

Wholesale Fittings - wholesaler - but they do serve JP.

 

[breezer]

jp being joe public. most wholesaler will sell anything to anyone, question is at what price

 

[securespark]

My point being that if you are desperate, and cannot source goods from elsewhere, then a wholesaler is worth a try. For a one off product, the price will not be too important over getting hold of the goods.

Mind you, in WF today, they sold a geezer an NB32 breaker (old style mcb) for 11 sovs. That's a lot, when NS breakers are under 4 quid.

ABM in Croydon do a 45A cartridge fuse for Wylex Standard Range for 9.80+.

If the Wylex unit does not have a 100A main switch, it is not designed for a device greater than 32A anyway. Check this out first.

also if you use a 45A cartridge fuse then you should use a cooker control unit without socket

You should be OK re disconnection times with 16mm, no?

 

[Technic]

This is an old wylex box with the mains switch rated at 60 amp and the cooker is rated at 30 amp so would i not be able to use 6mm cable and a 32 Amp MCB?

 

[ban-all-sheds]

For a 12M run with a 10KW cooker what fuse and size cable would you reccomend

the cooker is rated at 30 amp

Which is it?

 

[Technic]

On the plate at the front its rated as 10kw total output and on the back plate it states that it must be connected to a 30 Amp cooker point

also if you use a 45A cartridge fuse then you should use a cooker control unit without socket

You should be OK re disconnection times with 16mm, no?

afaict on a worst case TN-S you CANNOT meet 0.4 second disconnect with a 45A whatever the cuiurcuit cable is

a cooker cuircuit without socket only needs 5 second disconnect which a 45A cartridge meets easilly
