Just finishing a rewire, customer not sure on hob and cooker at design stage so I went for 2 circuits with 6mm withe 2 32amp rcbo's. Hob and cooker 5 meters apart. Now induction hob and oven have arrived onsite and both suggest a 13amp supply is suffice. Should I downgrade the rcbo's to 16amp and hard wire into plate or exchange plate for non switched fused spur and leave rcbo as is

Do they come with plugs?
Might not want to void a warranty single sockets might be better

Also 13amps seem quite small for an induction hob unless it’s a 2 ring hob.

How on earth are they going to void a warranty?

Are you referring to that utter nonsense about removing a moulded plug voiding the warranty on a whole appliance?

The RCBOs are to protect the cable not the thing on the end of it. 32 amp RCBOs are OK for 6mm cable. No need to downgrade.

If they come with plugs, change the outlet plates to 13a sockets and plug them in

Single oven will be ok.Customer has bought the wrong hob. 13A induction has to load share to work with such limited capacity. They should have bought the full blown 7Kw + model. They will hate what they've bought as soon as they use more than one hob lol.
As said above, leave the 32A RCBO's place and Spurs or plugtops will be ok.

That’s not quite true. I got simarly lambasted a few years ago on this very subject, and so did some ‘extensive’ research for myself. :)

Most of the manufacturers don’t give a hoot if you cut their moulded plugs off. However, I did find one or two that did. There were also some that required their original lead replaced, with an manufacturers one, if that is damaged.

Unfortunately, I never retain my research, so can’t tell you who was being a bit fussy. But recommend you read the instructions before getting out your snips.

At the end of the day the manufacturer's warranty is in addition to your legal rights. Your legal rights won't be affected by removing the plug. Your legal rights extend to six years as against the manufacturer's typical one year.

Again not quite true.

If a fault develops after the first six months, the burden is on you to prove that the product was faulty at the time you took ownership of it.

In practice, this may require some form of expert report, opinion or evidence of similar problems across the product range.

You have six years to take a claim to the small claims court for faulty goods in England, Wales and Northern Ireland, and five years in Scotland.

This doesn't mean that a product has to last six years - just that you have this length of time in which to make a claim if a retailer refuses to repair or replace a faulty product. (Which)

Obviously but I'm looking to protect the appliance also
If the cooking appliances do not come with plug tops, then the manufactures or consumers supply lead would/should be suitably rated, to carry the maximum fixed load of said appliance.

The oven I can believe, mine is 2.8kW so would be OK on a 16A RCBO. But a typical 4 ring induction hob is around 7.5kW so a 13A plug seems highly optimistic and needs careful checking.

I've installed plenty of induction hobs that come fitted with a 13A plug from the manufacturers. Seems pretty commonplace with them now.

Any modification to the original design " can " void warrantty,
that includes chopping off plugs.
Check with any lawyer they will confirm it.
Remember the law has nothing to do with common sense.
it is as it is !

Might be in Australia, but not so here in the UK.

if they don't come with plug tops, then you'll get a nasty belt off the exposed live parts in the plug.

32A RCBO, 6mm cable, single socket or preferably FCU with 13A fuse no problem at all?
In fact with that load a 1.5mm cable would be ample, as long as adiabatic checks out on the prospective short circuit current.
