    Earth leakage current issue (no load connected)

    I've come across a problem today that has completely stumped me. I used my clamp meter on the main protective conductor and found there was over 4A flowing. Checking the line and neutral conductors, they each had exactly 2A. Obviously these numbers do not add up as if there was leakage to earth...

    Hello all, Have just wired up a new Immersun 2; on switching the MCB supplying it, both earth leakage trips in my vconsumer unit knock off (strange as it's a split distribution setup - but BOTH trips go off). This also happens with the immersion heater disconnected from the Immersun output...

    Earth leakage and EICR's

    I have an installation that has an inherent earth leakage of about 15mA. The issue I have is that when I go to do an RCD test it trips due to the the additional current created by my MFT. Question is, if this was an EICR what would you code it as and why? My take on this is that 15mA is still...
