    EICR Test Fail, before and after

    Hi, recently had an EICR test done by 'Landlord Certificates' which failed due to circuite 3 having two radial circuits into a single 32amp MCB, they advised splitting it into two 20amp MCB's and quoted £174 including EICR certificate. The Electrian appears to have simply taken out the 32amp...

    AM2S Insulation Resistance Test on RCBO

    Hello, I’ve got my AM2S coming up and I’ve been revising like mad but I’m stuck on something. I’ve read that it’s a 3 phase board with just one RCBO for the ring circuit. Assuming they want me to do a global IR test, can I take the conductors out of the RCBO, switch it off, and then test...

    Can I confirm how to test for and how to find a borrowed neutral?

    During some testing I found a N-E IR fault on the kitchen lights of 0.1Mohms. I also found a N-E IR fault on the ring sockets, again 0.1Mohms. This could have been a coincidence, but I disconnected both neutrals from the neutral bar (i.e the kitchen lights and sockets) and tested between them...

    RCD tripping on test

    Hi, while testing the new board I installed I got to the live testing at the sockets one of the RCD's kept tripping during the loop test, the other ring tested fine so it's not the tester, the insulation tests where all good. Unfortunately I didn't have a residual current clamp meter with me, to...

    Has anyone on here using the Napit Fast test software for EICR's noticed that in the section "Extent and Limitations of Inspection and Testing" there is a box marked "Extent of Termination Sampling" which needs to be filled in. This must be a very recent addition, or it's been longer than I...

    I have moved back to my house i was born in some 60+ years ago. Most of the original house's electrical receptacles are 2 prong with the center screw that holds the cover plate on as ground. They all test, OK. My parents had an addition installed on the second floor sometime around the mid to...

    Stage 2 insulation resistance test

    I have installed a circuit for an oven and carried out all of the relevant testing so far. Apart from a neon on the double pole isolation switch, there is no current using equipment connected to the circuit yet as the property is empty. In this situation, would one just make a note on the...

    Does anyone use the UNI-T 528 test tool

    I'm wondering if anyone has used this tool. First of all I'm an automotive electrician but my work sent me on a PAT testing course and we have a DeltaPAT mi3309BT unit at work. I was thinking of buying something cheaper like this tool just to experiment with at home. I am 8 years away from...

    Is there a way to test a SPD without spending thousands ?

    I know there are many MFT's out there which can test SPD's, but they all cost thousands of pounds, and I personally can't justify that cost which currently isn't mandated. However it would be nice to know that when I install a SPD that it will function. Is there a way of testing such a device...

    My EICR test guy says I need to change my bathroom ceiling light to an IP65 rated.

    My EICR test guy says I need to change my bathroom ceiling light to an IP65 rated. Research says I need an IP44. The lamp is about 2.45m above the floor and about 30cms outside the side of the bath. Has he made a mistake or have I?
