Dual fuel FEEDER cable

[denial]

I have a shiny new Delonghi dfs090so gas hob / electric oven and an equally shiney new dedicated circuit (10mm feed, 45amp switch and outlet plate).
The manual suggests that the feeder cable section can be 230v 3x1.5mm.
This sounds a bit thin to me to be feeding a leccy oven!
Or am i wrong?
what the manual fails to tell me is the cookers power rating!
cheers and merry xmas.

then look for a rating plate on the cooker.

sounds like your cooker has a gas hob and electric single oven

how much did you spend on the new circuit then?

The circuit was put in as part of an extension with a dual fuel cooker in mind with possible upgrade (hence 10mm 45 amp ).
The power rating on the plate (which incidentlly is in the pan warming bit, not the back under the leccy cover (grrrg !) is 2515w.
SO :
It appears that 1.5mm should be adequate.
BUT: can i wire this into the connector plate without a fuse at the smallest point??? It will run straight off the 40 amp circuit !
cheers!!

1.5 is pretty tight if you use flex and not T&E. use 2.5. or even better, use 4mm² (after all, its only protected by a 45A MCB. 1.5mm² will have burnt the place down before the MCB switches off)

how did you manage Christmas dinner?

seriously though, you could use a 13A FCU where the 1.5mm² begins but getting the 10mm² cores into the FCU will be very tricky. Best to change the 45A MCB to a 16A one. Then if someone needs the 10mm² cable in future they can upgrade the MCB.

Denial,the easiet way of achieving what you want to do is to connect the unit into the coooker connection plate..BUT replace the MCB in the board. Change the 45A on for a 10 or 16A Type B breaker. That way you are not risking the entire circuit.

This will actually be the cheapest option and the easiest to perfom.

Rewiring the cooker would risk voiding your warranty..not a good idea...

Installing a 13A SFU would cost about £20 all in and be a bit of messing about...

Changing the breaker would only involve the purchase of the breaker (about £6 depending on make and suplier), turning off the CCU for a few minutes, removing the 45A breaker and replacing it with the new one, replacing the cover, and turning the power back on...

Job done...
