    Advice on EICR fail

    The buyers of our flat (upper floor of a two flat building) have just had an EICR done and it has flagged a number of C1’s and C2’s.

    Insulation LN Test Fail through cooker isolator

    As it says really. When testing LE or NE resistance > 300M ohms but between L and N I was getting a reading of about 0.2M ohms.

It might’ve...

    Hi all, Does anyone know of a training provider who concentrates solely on what's in section b?? We have a guy on our firm who does all out test and inspects and doesn't explain anything and college is more concerned about getting bods enrolling than actually training them.
