A question on the "Continuity of CPC and Polarity" test using the Megger MFT.
I've recently purchased the Megger MFT and been using this for multiple tests.
On lighting circuits, the above is very easy when we are looping at the switch and there is only one wire going to the light. You can easily locate the Switching Line and Earth for the purposes of the test - at ceiling.
This is not so easy when you are looping at the ceiling and potentially have the following cables:
- Line In
- Line Out
- Switch
- Additional Light Feed
- Smoke Detector
In the above situation I tend to use Ideal Connectors which I shove above the ceiling plasterboard and only have two wires coming down to the light: Switching Line and Neutral (Earth is not required for this light fitting)
Similarly, my external light is also assembled in a series of Ideal connectors inside an adaptable box.
I suppose it's a case of performing these tests before fixing wires into the Ideal connectors or always ensure that an earth is also coming down to the light fitting?
I would appreciate your advice around how and when these test are handled. Thanks in advance.
