[QUOTE="SPECIAL LOCATION, post: 519161, member: 250"] What are the R1+R2 values? and are they proportionate to the length & CSA of the supply cable? Have you compared how much of a difference are you to the actual Max Permissible in BS7671? If the difference is not massively off the expected values.. Could be a poor joint somewhere.. Could be down to poor connections between your test meter & the circuit you are testing.. Could be dirty contacts on a switch / isolator somewhen along the circuit.. On old existing circuits its not uncommon to take a reading that initially appears outside of its expected values.. sometimes a bit of further investigation can give a different perspective..
