Domestic kitchens

[Toshie]

When wiring a domestic kitchen is ok to supply integrated appliances from 32A/ 2.5mm ring via 20A D.P. Multi grid Switches , using 2.5mm on out going side of switches to a 1 gang socket or spur ?

Out of interest, in what circumstance would you not need to use 2.5mm on the outgoing side? And even if you didn't need to, why wouldn't you?

I suppose if it’s 13A fused you could go to the outlet in 1.5mm..... but normality insists it should be 2.5

Out of interest, in what circumstance would you not need to use 2.5mm on the outgoing side?

When the cable is

a) Adequately protected from overload by a downstream device and/or the nature of the load.
b) Adequately protected from faults by the upstream device.

And even if you didn't need to, why wouldn't you?

To avoid waste, and have an efficient design.

Looked at the other way, why would you use an oversized cable?
