Electrical Advice - New Consumer Unit

zax47

We/you would need to know the rating (kW) of each of the device to be certain, but it is good practice to keep two high current devices on separate circuits.

Yes I am in process of sourcing the oven and hob so dont know the values as yet to know for sure.

As it looks most likely a new CU will be needed I need to think about what/how many circuit I will require.

Do people use a dedicated cicuit for white goods such as Fridge/Freezers because of the possibility of earth leakage ? Would they also go on the non RCD side of the consumer unit ?

Could end up with alot of radial circuit
1 x cooker - non RCD side 45A depending on requirment
1 x Hob - non RCD side 45 Andepending on requirment
1 x Fridge/Freezer non RCD side 20A ?
1 x Sockets Kitchen RCD side 20A
2 x Lights up and down stairs Non RCD Side 6A
1 x Shower RCD side 45A
1 x Washing Machine Non RCD Side ? 20A ?
1 x Dishwasher Non RCD Side ? 20A ?

As a rule of thumb a hob is around 5-6 kW and a oven is around 3kW for a single compartment and 5kW for a double oven.
It is far easier to work with 2 seperate 6mm 32A circuits than 1 45A circuit from a wiring and practicality point.

I personally think it makes a better job.

Another point the older Wylex consumer units have a main switch rated at only 60A, so if you have a shower there is no other place to put a 40 or 45A circuit (there is only 1 space suitable in these older consumer units)

I would personally suggest you go for an upgraded consumer unit as it will make the whole house safer
