I've just had a long conversation with a NICEIC inspector regarding which RCD out of a 30mA and a 100mA would trip with a fault current first?
Now maybe i've just gone mental or something but everything i know points me towards the idea that the 30mA would trip first, however the guy from the NIC swore me blind that 100% of the time the 100mA would trip first.
Has anyone else got any experience of this? I'm quite prepared to accept i've gone mental and this guy was correct. It just doesn't make any sense to me.
Thanks
