How many applicances of 32 amp mcb

Anonymous user 28/02/2024 - 4.00 PM

Hi all, firstly sorry for long post. I'm replacing my kitchen and when looking at new appliance's I noticed some ovens need to be hardwired and say they should be on a dedicated circuit. The oven we have now just came with a 13amp plug already on and just plugs into a double plug socket along with the gas hob. If I got another oven with a plug would it be ok to just plug in on a double socket with the gas hob, as when I looked at consumer unit i noticed the kitchen just has one 32 amp MCB feeding it. We haven't have any problems with tripping electrics only when the heater element in oven went and motor on washing machine went and the electrics tripped but once I replaced parts they were fine (could the appliances broke because two many appliances are run off same circuit or would it just trip electrics if it was over powered rather than breaking appliances) We have a kettle,toaster,microwave,extractor hood, separate extraction fan,washing machine,dryer,fridge freezer,house phone,single built in oven with 13amp plug and a gas hob all coming of same 32mcb is this to much and do we need some on there own dedicated circuits and if so which ones. Many thanks

Bs 7671 recommends that cooking appliances rated 2kw or above should not be powered from existing ring final circuits as overloads could occur and ideally should be fed from a dedicated supply. However thousands of ovens are indeed plugged into the nearest socket. If your ring is actually still a ring then you won’t have any issues apart from potential for nuisance tripping when the toaster oven and kettle for example are all used at same time. If your ring has been modified and has no continuity then this could potentially cause some issues. If your in doubt just book a sparks for an hour to test things for your peace of mind.

As long as your circuit you are using is classed as a ring main (2 cables at the consumer unit each 2.5mm) and should be protected by a 30ma rcd (primary and secondary protection) the inrush load even if you put on more appliances a 32amp type b mcb will be OK as in short term it can take approx 60 amps due to the inrush curve.
