[QUOTE="Markiemarque, post: 86506, member: 3196"] Hi, I am getting a very low reading on a lighting IR test (close to zero!). The circuit is an existing domestic lighting installation that needs testing. Due to the high number of dimmers I am using the L&N to CPC test to avoid damaging any sensitive equipment. The lighting circuit appears to work okay ie. it is not tripping the CB in normal use. I cannot identify any equipment on the circuit that would give this type of reading .... any thoughts? BTW - I would not expect to get a low reading doing L&N to CPC there is no potential difference across the Line and neutral .... am I missing something obvious? All the other lighting circuits are fine + there are also emergency lights off each lighting circuit. Thanks Mark [/QUOTE]
