Hi all, yesterday i went to a property to do an EICR in preparation for a DB change next weekend. The existing DB has six circuits, cooker, 2 x rings and 3 x lighting circuits. Bonding to gas and water is in place and adequately sized so providing everything tested out ok a relatively straight forward job.
Other than a high resistance on one of the ring final circuits ( live-live) which was identified and put right i had no other problems with either ring or the cooker circuit. My first question is when i change the DB am i able to use these existing readings? Nothing is changing in regards to the wiring. I still need to perform an RCD tripping time test once the board is changed as there are currently no RCD's in place, but all my other test results for the 2 x rings and cooker circuit are fine.
And now for the 3 x lighting circuits! Had no problems with my r1 - r2 readings on any of the three circuits. However when it came to my IR test my readings were quite low although still greater than 2Meg. It wasnt practical to remove every lamp from circuit so my IR test was done between L-E and N-E, with the circuit completely removed from the DB. The lowest i got was greater than 10Megohms. I couldnt find anything on the circuit that might be bringing this reading down. Im happy enough to connect to the new DB without there being a problem with nuisance tripping but should i test these circuits again removing everything from circuit or simply record my low readings.
