Oven on FCU? But what size fuse?

That information is contained in Appendix 15.

What app 15 says regarding connecting cookers etc over 2kW to their own dedicated circuit is not a regulation it is a method of ensuring the requirements of reg 433.1.5 can be met. What is important however is reg 433.1 which states "every circuit shall be designed so that a small overload of a long duration is unlikely to occur". I would suggest that putting a 15A cooker on a 13A fuse contravenes this.

But isn`t it unlikely that the cooker will pull that much anyway?

 

[JD Hogg]

Yes, thinking about it the oven would get up to temperature, probably pulling 15A then the stat would switch it on and off as required so the overload wouldn't be a long duration.

There is no way 15A would blow a 13A fuse so feeding the oven via a plug top is OK then??

Appendices in the regs are 'informative and are provided as guidance' - which means they don't have to be followed exactly.

This was highlighted recently to me by an ECA assessor.

Excepting Appendix 1, which is normative and is thus a requirement.

If that oven ever see's 15A it'll be a miracle!!! This is almost becoming a daily occurance on the Forum, of where sparks can't get it round their heads that these ovens are rated at ''connected load'' and that connected load is unlikely ever to be seen, because there are heating/cooking elements that cannot be utilised at the same time!!!

Some of the posts on this thread, clearly indicates that there is a lack of understanding whenever they come up against cookers, ovens, and split hob and oven set-ups. They still look at the total KW rating and start panicking, and up goes the size of the cable and the MCB rating, all to the cost of their customers.

This oven can go on an FCU with a 13A fuse, ....end of!!!
