as murdoch said. MI says a 16A supply, so that's what you need to do, even if it never pullls over 13A.
 
I noticed something on another forum saying that it is possible to take a mini CU off the downstairs ring and fit a 16A MCB to it which would supply a cooker point.

So the 32A MCB at the main CU would supply downstairs ring plus a mini CU.

Am I right in thinking that the regs state nothing above 13amp may be connected to RFC?
 
Hi - many things in life are possible, but some are not recommended.
AFAIK there isn’t really a regulation prohibiting this exactly, but IMHO it’s not in accord with Appendix 15 and perhaps Regulation 433.1 (design so that a small overload of long duration is unlikely).
Another way of saying it - if a student submitted this design at college it wouldn’t result in a pass.
 
Beeg, the OSG advises this:

H2.5 Permanently connected equipment
Permanently connected equipment should be locally protected by a fuse complying with BS 1362 of rating not exceeding 13 A or by a circuit-breaker of rating not exceeding 16 A and should be controlled by a switch, where needed (see Appendix J). A separate switch is not required if the circuit-breaker is to be used as a switch.

So the IET have no problem with what you propose

Thanks Wilko. I’ve swapped the oven for one fitted with a 13amp plug but had I kept it, an electrician wouldn’t have connected it in the method described above and would have have insisted on installing a new radial circuit from the CU?
 
Myself, I wouldn’t likely be putting a new remote CU for a cooker on top of a B32 RFC. If it needed it’s own B16 it would be sitting in the CU and feeding the appliance in the usual way. But that’s just me, I can’t comment on what someone else would do.
 
That's fair enough Wilko, what you say would certainly be better practice. There are times when best practice is hard to achieve - no spare ways in the CU, expensive decoration, you know the sorts of things. It's nice to have other options which, while perhaps not ideal, will still get the job done
 
Sorry to ask yet another question on this thread.
I’ve found an oven which is 13amp but it doesn’t come with a plug and says it must be hardwired.
Does anyone have any idea of the reason for this?
Is there any reason why a plug can’t be fitted to it?

Thanks again
Beeg

ETA... I appreciate that MIs should always be followed, I’m just intrigued as to why this might be the case.

They are not manufacturers instructions, just the advertised spec.
