Hi All,
I am due to start year 2 of C&G2330 L2 in September and wish to get my head around RCD ratings. I think I have grasped the principle of how they work eg: ensuring the line and neutral currents balance. However, I am not sure about the ratings printed on the units themselves.
Looking through numerous catalogues, I see that they have 2 disconnection related figures quoted eg: 63A 30mA or 40A 30mA but I am not sure what these figure relates to.
If anyone can assist I would be most grateful.
