What are the trip times for a 30mA RCCB?

Several standards define these times (AS/NZS 61008.1:2004 and AS/NZS 61009.1:2004). At 30mA the trip time must be less than 300ms. Increase the residual tripping current and the tripping time decreases, eg at a residual tripping current of 150mA (5 x IΔn) the RCCB or RCBO must trip in under 40ms.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
