Hi everyone, I'm replacing an MCB with an RCBO, the MCB is looking after a downstairs ring main, and there is no RCD cover. the question is how do I test the RCBO, for example is the testing the same as for an RCD , ie x5 and x1, if so how is it done?

With an Alphatek, you need not worry about electrocuting the housewife as she washes up.
With an RCBO of trip rating above 30mA, the 5x test is not applicable.
