Hi
I have been practicing some dead testing on my home CU prior to my level 3 C&G in Electrical Ins begins.
I carried out an Insulation Resistance test on the downstairs ring and was concerned to see a reading off 0.00 M ohms between Phase & Neutral , N & CPC was 4.96Mohm & Phase&CPC was 4.96Mohm.
0.00 would indicate to me I have made a mistake with the connections or the test but I had the 6 cables disconnected from the CU and my connection was via the leads with the crocodile clips on the end i.e. 2 Phases and 2 CPC'S , 2 N's and 2 CPC's and 2 phases & 2 N's.
Could the insulation resistance really be that low ?
Any ideas most welcome
Regards
