An outdoor door socket with inbuilt RCD i installed trips the CU RCD when the test button is pressed on the socket. both are rated at 30ma, but I would of thought that the test button on the socket should not trip the CU RCD, Does this mean its a faulty Socket/RCD?
Also if the RCD trips in normal use, should this trip the CU RCD, as its the same rating?
Cheers
