Sorry if this is obvious but I thought discrimination was for down stream?
I want to feed and outdoor unit which only requires 6am and 16amp, it has a little sub board with these breakers but a 100a main switch, my supply is a 32a commando outlet.
Should I feed existing sub board with existing armoured to adaptable box and connect through, coming out with a flex to commando, since you can't make off the armoured to a commando as armoured has no earth?so need the steels to bang for earth
Or simply run a new cable to feed 2 spurs feeding the lights s, power with a commando the other end, outlet has an rcd on it.
