Bit confused here, IR testing.

[Thommo]

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

Circuit breaker should be off as long as you are on the load side. And as stated when doing an IR test ALL SWITCHES SHOULD BE OPERATED.
