Hi all.
I am finishing my level 3 in electrical installations and as such, I have tried to explain this to a friend.
So much so, that now he's got me doubting myself.
He's powering his garage which is attached to the main house.
He's also providing the circuit supplying the garage with RCD protection.
At the garage consumer unit, he's got a standard 40A RCD 30mA protecting a 32A type B and 6A type B MCBs.
My advise for him was in terms of the given protection to the both circuits in the garage and the circuit from the main consumer unit to the garage. He's not providing discrimination as both RCDs are rated at 30mA.
Now, he's adamant that discrimination has been given as one RCD is 63A and the other is 40A.
Am I wrong when I say that discrimination hasn't been given.
Kind regards.
Albert
