WebThe tripping characteristic for a 30mA RCCB is also shown in the graph. It shows the level of current required to cause the RCCB to trip, for example; 50mA will cause a trip but not 10mA. Comparing its characteristic with the various zones on the graph it can be seen that the 30mA RCCB gives a very good measure of WebAug 5, 2024 · In my CP there are 2 RCCB one with 500 and another 30 mA. ... Odd that the higher tripping current is used in the more hazardous wet locations. I would definitely be tempted to replace it permanently with a 30mA unit. Yes, I was surprised, maybe it was the standard in 1981.
