Question: I am sure I've read somewhere that an appliance rated over 5.5kW should be supplied by a dedicated circuit. I come across this quite often - in kitchens, for example, where (typically) a hob of 6+ kW and an oven of 5+ kW are installed. The kitchen firm involved in this case wants both on a single circuit. I disagree, and think that separate circuits are required, but can't find out where I read this. Any help would be appreciated.
Answer: The IEE on-site guide gives guidance on cooker circuits. It states that a 30A or 32A circuit is usually appropriate for household or similar cookers of rating up to 15kW. It also states that a circuit of rating exceeding 15A, but not exceeding 50A, may supply two or more cooking appliances where they are installed in one room, but the control switch should be placed within two metres of each appliance.
