Obviously i have not put the busbar in yet but u get the drift.
Main switch on MCBs off RCD ON then test load side of RCD line to earth for that particular RCD or like not so clever pointed out if the RCD side you are testing has a circuit using socket outlets then just use the plug on the megger and test at socket outlet.
first test 1/2 then 1 then 180 wave then 5 then 180 wave record two highest results. The 1/2 test should not trip this is a test to gauge how sensitive the RCD might be ?
Then finally test the manual button on the RCD to see if it works.
