I am, wiring up a load of new ccts .....I have 2 CU's and arranged to
provide 3 discrimination classes - no RCD protection, 30mA RCD protection,
and 100mA protection.


The question arises on Cookers & Immersion Heaters ?

I know there is no requirement in the regs for protection, but have always
had these via protected ways in previous houses .... what is the current
'best practise' for cookers & immersion heaters.

No protection, 30mA or 100mA ?
