Electric Oven Install

[ajagani2009]

I have just had a new electric oven which is 2300W at 220-240V (Divided makes 10 amps) hardwired onto an existing circuit with existing wiring. The oven can also be plugged into a socket so can work with a 13 amp fuse. The previous oven was 2800W at 220V (Divided makes 12.72 amps) and was also hardwired. The faceplate next to the cooker has a socket for a 13amp plug and a switch for isolating the oven, so just the 2 appliances for the circuit. (this also controls the ignition for the gas hob)The circuit breaker is rated as 32 amps and we have had no problems with the previous oven, as such assuming the wiring can handle 32 amp my question is should I now need to decrease the circuit breaker to 15/20 amps as the or will the existing 32 amp breaker be fine? I am concerned that the breaker will not trip until the oven's demands 32amp be which damage to the circuit will occur

What cable size is the circuit on? They'd be no need to lower the Fuse, the Oven shouldn't create an overload current that high unless there was something seriously wrong and if it did the 13A would blow if you're using a Plug for it?

The oven is working at the mmoment . It is already harewired and not pluged in via a 13 amp fus so is connected via the into the existing wiring - not sure of the cable size but as it as old oven worked with no isssues for 17 years with the current cable 32amps) so a assuming it is fine.. I am unsure whether the amps are too high in the circuit breaker (32 anps) amps I am usure I should decrease te Circuit break

You don't need to change anything.
The 32A circuit breaker is there to protect the fixed wiring, which hasn't changed.

As above, you're good to go and the oven will never demand 32 amps.

Interested in this, so what is the largest demand you can put on a 13 amp plug in Watts? Ta. 2990?

 

[flameport]

2990 or roughly 3kW is the maximum. However they are not suitable for items which will draw that current continuously for hours, such as immersion heaters or EV charging.
Some cheapo plugs and sockets have been known to overheat with a lot less load.

Thank so much for all the advice it is much appreciate
