Installing an electric cooker

dbs

Just bought a secondhand cooker old one installed with 6mm t&e cable from consumer unit with a 32amp MCB to a 32amp operating switch.

The new cooker states it requires a 45amp double pole operating switch because it is more powerfull.

Will it need a 45amp or higher rated MCB
Will the 6mm t&e cable from the consumer unit need replacing for a higher rated cable?
Cable run is no more than 8 metres long.

Its not quite that straightforward, from what I remember 6mm T and E will take that current provided it isn,t run through insulation - Just remember to apply diversity to the cooker, you need to know the ACTUAL load of the cooker with everything on, then take the first 10 Amps and 30% of the rest of the load and add 5 A if you have a socket with the isloator, that will give a better picture of the real life load. Sometimes the voltage is quoted at 230V sometimes at 240v. For a 10Kw load this makes nearly a 2 amp difference. That being said, you may do better if you use a 40A MCB and rerun the cable in 10mm. I'm sure you will bear part P in mind too! :rolleyes: Just like I do LOL.

Cant find the total power rating of the cooker, only 1200W,1500W,1200W,1800W solarglo rings, unable to find the power ratings of the ovens in the instruction manual but it does state the power supply cable should conform to B.S.6004 with a conductor size of 6mm minimium.

Checked the cooker itself but it has not information plate on it.

Mr_Proctalgia

If the instructions say you can use a 6mm cable then you should be OK with it, I would get yourself a 40A MCB fitted on the CU - Change the isolator as you feel fit, after all how often do you isolate a cooker with everything going full belt! I would suggest that if you have access to a meter you check the insulation resistance between LN and E going into the cooker before you fit it.

I just wanted to remind you about the warning at the top of this board:

Announcement: Warning! Always use a professional for gas maintenance and complex electrical repairs. Being safe is more important than MoneySaving.

I would just like to echo Pink-winged's comments here. This forum is primarily for moneysaving aspects of DIY. Complex gas and electrical repairs should only be attempted by a professional.

I agree safety comes first I normally check with an electrician at work(but on holiday at the moment) then buy my parts from a professional supplier for further advice then I double check any work I have done before I turn the power back on.

I work as a factory maintenance fitter and have been trained to undertake electrical tasks.
