OK. Id be very grateful for some experienced testers opinions regarding how they would proceed if they were in my shoes.
I accepted a contract carrying out EICR's for a social housing contract.
Now, I havent been doing EICR's since 2015. Back then I would charge a day rate and test every circuit 100%.
Probably the biggest part of how I used to do things was disconnecting every last piece of current using equipment and doing I.R between neutral and line, line and earth and neutral and earth. It used to take a lot of effort to find every piece of equipment and often things were found which the customer, despite living in the property all their lives didnt know existed.
Here I have 1.5 hours per property, we arent allowed to leave FI, C1 or C2 problems (withing reson of course but generally theres a lot to sort out)
1st question - If your R1 + R2 value is lower than either your RN or your R1 continuity tests - What would that tell you and what would you do to prove the circuit is ok for continued use in its current state?
2nd question - If you had either excessively high, or no continuity on R1, RN or R2 end to end readings, how can you quickly and simply prove the circuit is stilll safe for use without getting deep in to further investigation?
3th question - When doing an I.R test whereby........ line+neutral are connected together and tested to earth - Is there any electronic or electrical device which, if connected, could result in a test failing the circuit? I had one today 0.79 ohms
