Rcbo On A Busbar Protected By Rcb

[E.E.I]

Hi just looking for your opinions on putting an RCBO on as busbar protected by an RCD, the reason i ask is the manufacturer doesnt make a 45A MCB but does make a 45A RCBO.

or leave the circuit on a 40A MCB even though the manufacturer of the oven asks for a 45A supply?

What makes the board?

I very much doubt the cooker will pull 40A let alone 45A

What make and model of cooker is it?

The board is Eaton memshield 3

The cooker is a Belling Classic 90E they recomend a 45A supply but from memory i think its about 15kW, im guesing they have taken diversity into account.

Cooker switches are rated at 45A. That's probably what they mean.
What's the worst that will happen if you keep it on a 40A MCB instead of increasing it to 45A?

Thats never going to happen.

Our cooker is rated at 17.7kw. Its on a 40A MCB (but according to the manufacturer it could be on a 32A, but I ran 10mm when we rewired). Never tripped the breaker yet!
