I took this to mean electrical installation certificate for new circuit, periodic inspection report for installation testing, am I on the wrong lines cos I did have to read it a few times!
functional testQ. What test would you do on the rcd? (8 marks) I think it said to include time, mA
what size rcd? if 30mA then
did it ask for tester used etc better if you get a copy as the C&G speak needs to be read fully to understand there geeky language lol
A. Residual current device testing
test at 1/2X 15mA at both half cycles no disconnection
then test at 1 x 30mA at both half cycles disconnection in 300ms
then test at 5x 150 mA at both half cycles disconnection in 40ms
Q. What other test would you carry out on the rcd (2 marks)
