oven wiring a 2.4kw oven

Connecting cookers,oven and hobs with a rated power exceeding 2 kW on their own dedicated radial circuit. Appendix 15 BS 7671:2018.

Because if you just plug it in it will put load on the ( probably) loaded kitchen circuit. In a domestic situation anything over 2 kw is not supposed to be plugged in. Apart from all that manufacturers instructions should be followed, therefore it needs hard wiring on own circuit.

If the oven is designed to be plugged in via a 13A socket then it will be supplied with a factory fitted flex and moulded 3 pin plug If no flex is fitted ,likely to require hard wiring back to the CU, with local isolation, usually in adjacent cupboard or above worktop

It’s usually inappropriate to add a 2KW load to a ring circuit especially in a kitchen where it is likely other high current devices will share the same leg of the ring, such as kettles, toasters, washing machines and dishwashers. Regardless of the location general guidance is given in Apendix 15 of the wiring requirements that fixed equipment of 2KW or higher should be installed on a dedicated circuit and not spured from a ring final. Some manufacturers will supply ovens with moulded plugs, they will have tested the diversity of the situation and concluded that although the device may be capable of consuming 2KW of power in reality it is unlikely to for a significant amount of time... Another device not supplied with a plug will have performed differently although its rating is the same. The stated power consumption of an oven is likely to be its maximum possible power consumption not its constant power consumption as the elements will cycle in and out. If it ain’t got a plug then the general rules of Apx 15 will apply, if it’s got a plug then it’s the manufacturers problem.
