Help! New 2.5kW oven + 6.7kW hob - 40A fuse

[Piotr Orlowski]

Hi. I need to replace an old oven and hob. Currently the oven is 2.3kW and the hob is 5.8kW. They are both hardwired into the same connection unit, then it goes to a 45A cooker switch with an integrated 13A switched socket, then it goes to the 40A fuse in the consumer unit.

The new oven is 2.5kW and the new hob is 6.7kW. Fragments of spec below.

BEKO HIC64402T Ceramic Hob

Hob power - Front right: 1.5 kW / Front left: 2.2/0.75 kW / Rear right: 1.7 kW / Rear left: 1.2 kW

Electrical installation - This product requires hardwiring to a 32 Amp fuse.

Power supply - 32 Amp (Requires hardwiring to a dedicated cooker circuit)

BEKO Pro BXIM35300X Electric Oven

Energy consumption - 0.94 kWh

Electrical installation - This product requires hardwiring to a 16 Amp fuse.

Power supply - 16 Amp (Requires hardwiring to a dedicated circuit)

Electrical power rating - 2.5kW


The question is - are these new appliances suitable replacements or should I look for something with less total kW? Will the total load be too much while cooking on the hobs and using oven at the same time? We very often also use the integrated socket in the cooker switch while cooking to charge a mobile phone etc.

Thanks,

Piotr

What is the size of the cable?

 

[Piotr Orlowski]

The cable is 6mm. About 6-8 meters from consumer unit with 40A fuse to 45A coocker switch with integrated 13A switched socket and then to connection unit behind the oven. Both oven and hob connected to the unit. All other sockets including fridge are on a separate ring/fuse.

Never in a million Xmases will the oven and hob be drawing full current together.

As teletrix says^^

Agree. Hob and oven will not both be drawing full current at the same time.

Although plugging a phone charger into the socket may just push it over the edge.

If all were on then there was a short power cut, when supply comes back on all will be on together temporarily..
(Just saying )
