Wiring electric cooker to socket Ask questions and find answers to many subjects relating to electrics and electrical work

Need some advice on wiring electric cooker to a double switch socket box on wall.Replacing a gas cooker. Have a 35 amp fuse connection seperate from normal fusebox, running to socket. Opened up the socket box, and found cable (red, black and earth) connected from mains to socket switch only. Do I simply need to connect a 6mm sq. cable from base of cooker and feed it to the terminals for cooker switch?? What precautions and advice do I need? Thanks a mil.

hi.
not entirely sure, but if I understand you correctly you have what is sometimes done when an electric cooker's not wanted initially.
A cooker point is wired but a double socket is fitted instead of a cooker switch. If so then the socket must be changed for a cooker unit, with or without a socket on it, you cannot just connect from socket terminals to the cooker as there would be no isolation point for cooker which is required,

thanx for tips. just discovered a volex 45a cooker switch with smaller switch for the socket. Would that suit the 6mm sq cable fed from cooker to socket box?? i would like to keep the socket available The cooker is 10300 watts with 230v = 42 amp. there is a 35 amp fuse beside fusebox. What fuse would i need??

Hi again,
yes that would be fine to fit in place of existing socket on a 6mm cable as you say 35A fuse? are you sure it's not a 32A ? 35's an odd size.

As for load, 10.3 kW is around 44A but as I explained on another posting recently, their is an allowance in the regs for 'diversity' on cooker circuits which says you take:
10% of total ie 4.4A plus 30% of remaining load ie
[44-4.4] = 39.6A/30%= 13.07 + 5A for socket on panel, so total assumed load = 4.4+13.07+5=22.47A, well within your supply.
'On site guide' gives rule of thumb that any cooker up to 15,000w can run from a 32A cooker circuit,
