Radial circuit split 2 ways

[Bradley6969]

Hi all, working with a spark today, basically dodgy wiring in kitchen junction boxes everywhere, all ripped out, now all we’re doing is a new 6mm cooker feed and radial socket circuit, basically new 2.5mm radial circuit from CU to one side of kitchen where spark I’m with has decided to put a Wago box to feed half one side of the kitchen and half the other is this acceptable? So 2.5mm in and X2 2.5mm out on 20A breaker one side feeds X3 sockets and X3 other side, personally I’d put 4mm radial in on 32A but there’s no heavy load apart from toaster and kettle, just my question about the radial circuit.
Thanks

Yes that's fine as long as the cable calculations are good.

If it's a new circuit being put in would it be wise to give it a bit more current availability. Could it not be a 32A ring final?

There’s literally X6 sockets, most on at same time is microwave and toaster, I personally would of done either 32A ring or 32A radial but my boss allowed for only a 20A radial

His choice I suppose. Seems a bit limited for a new kitchen circuit.

Yes and no, there’s no appliances being plugged in washing machine,dryer are all on main ring in a different room I see both ideas though.

 

[DPG]

Ah right, appliances not in kitchen then.

 

[littlespark]

For a kitchen I would future proof and go with a 32A rfc.
Even if the big appliances are in a utility room, that’s still possibly a microwave, kettle, toaster... then they bring in a foreman grill, a coffee machine, a qooker hot water thingy at the sink, a dishwasher.... the list goes on.

As above. Or 4mm 32a radial. The 20amp in the kitchen will easily get stressed out.

 

[Bradley6969]

Thanks guys all done and finished now, I will speak to my boss as I did actually point this out before we started but he pays the wages, appreciate your time
Cheers

This all sounds like a YouTube video I recently watched

For the cost of a few meters of 2.5 to complete the ring must of cost the Wago box and connectors cost spent on them.

Who’s that? I’ll give it a watch?

 

[Bradley6969]

Yes I agree but not up to me, just was unsure of splitting of the radial mate

IMO lazy 20amp radial for kitchen, there may be trouble ahead.

No toaster allowed - lest it trips cheap smoke alarm

Kettle only tee hee hee

 

[bigspark17]

Terrible design. 20A load for kitchen is going to cause endless problems for the user and future users. Tell your boss hes a lazy git!

 

[davesparks]

Without knowing further details of the kitchen how can people be so certain that 20A isn't suitable?
And what is the actual average and peak demand for a typical domestic kitchen socket circuit?

 

[bigspark17]

OP states kettle, toaster & microwave. Do the maths dave..
not saying you would do it but as its a general forum i think it should be clear 20A is not suitable for a new kitchen.

OK,
Modern kettle 2400W
2 slice toaster between 800W and 1400W
Microwave between 700W and 1000W

Taking the higher ratings gives 4.8kW which is bang on 20A
If you adjust for 230V it'll probably come out around 18/19A

But then that's completely ignoring diversity and the fact that someone would need 3 pairs of hands to operate them all at the same time.

Actually not inconceivable all of them items will be operated at once. Mine are quite often at home.

However, you're right it's still within 20amp and how longs a kettle take to boil? 30 sec if that.

Set our minds at rest .
Do you have a separate laundry room , or are the Dishwasher ,washing machine ,and tumble drier? All sitting in a spacious kitchen.
