Hi, are there any reasons apart from faulty RCD that can be tested and what sequence of tests should I follow ?
I have a 100amp main switch with two MCB protected lighting circuits, and then a BS EN 61008 80a 30ma RCD with two 32a sockets circuits, a 16a heater circuit and a 6a security alarm circuit.
The RCD fails 1/2 test 0 and 180.
Trips at 12.9ms at 5x.
Gives a reading >400ms at 1x.
I am using a certified (calibrated) MFT and testing from a local socket in the installation.
thanks.
