Kitchen Appliance circuit

[Snapester]

Designing a kitchen appliance circuit, i plan to feed a bank of grid switches with a 6mm T&E fed via a 32A MCB, then each switch will have a 2.5mm cable to a fcu supplying an under counter appliance.
My main question is, is it ok to change down to 2.5mm and then feeding the FCU? As the cable cannot be overloaded as the main load is connected to the FCU at position?

Regards

but the 2.5 is protected by 32A, but im talking basics so hold up for an expert

yes.....minimum feed for an FCU is 1.5mm by the way......

come on I=P/U....you gonna try stuffin 4mm or 6mm into the back of an FCU?...lol.....

Is that down to the reg which states 1mm is only allowed on lighting power circuits?

 

[telectrix]

can you get 2 6mm cables in each terminal of the switches?

 

[Snapester]

I=P/U if the connected load is protected by the FCU then the 2.5mm cannot be overloaded hence protected.

i read it as 6mm to switch bank, then 2.5mm to each FCU. but doubt if could link switches in 6mm

 

[Snapester]

telectrix yes that is a valid point! Maybe i will run a 4mm 20amp radial i will check the calcs!
I should have thought about that one damn! This is why you guys are good to run it through with!

sso what stops me from adding a light off 11kw shower in 1.5 , sure the light will only pull 40W... thats my point..

Why not just run a Ring in 2.5? even if it is only to the grid switch it will be hell of a lot easier to terminate. You could keep it on a 32A Breaker then.

yes...it was meant in jest more than anything else....

 

[Snapester]

I=P/U nothing as long as you protect it via FCU

so i take it hes in a commercial kitchen with lot of appliances and wants to switch them from the door.. so how would you go about this.

and detailed for the impaired glensparks
