I think the fact that you have stated you are testing a single circuit changes things somewhat from your notes. If you are carrying out a global test (as per the notes) then all conductors will be connected and protective devices on, with the DB main switch OFF! Your test will clearly be carried out on the dead part of the DB.Hi all, this is probably a daft question to most of you.
At training centre I have started dead testing. When I get to the 3 point IR test on a single circuit should I switch off the breaker for that circuit .Hopefully I am correct in removing any lamps on a lighting circuit and turned switches on with all points closed. On a radial or final ring I have closed all points turned sockets on.
I think the procedure may be different when doing a global test, not sure.
Just a bit confused about the circuit breaker as I know it is switched on for continuity of cpc test.
Thanks in advance for any input
But you have stated you are carrying out a test on a single circuit, which is not what your notes are describing. This should be carried out with the line and neutral conductors of the circuit disconnected from the DB but with the cpc still connected to the earthing system.
