    Battery tester that test batteries under load

    I am confused about battery testers for house hold batteries, AA, AAA, 9V, etc. Recently my smoke alarms started chirping so I changed the 9V batteries and no chirping. However, the replaced batteries tested good using GBT-500a battery tester. I was told that batteries need to be tested under...

    Hey all, Could do with some help. I had a company recommended to me who quoted me to do an EICR on my rental property. (£265). I thought this was quite expensive but as I've been messed around no end by tradesmen I thought I'd go with the recommendation and pay the extra. I also asked him to...

    How to test RCD when RCD is RCD protected?

    Got a sub main board with an RCD inside. Need to test that but whenever I test it it sometimes trips the RCD from the main board. I need to test the RCD from the sub main board. Any suggestions? My thoughts are to bypass the RCD at the main side with connector blocks momentarily but surely...

    Continuity test after Ring Circuit

    After completing a new RFC or modifying an existing one, I will always test continuity across all 3 conductors at the Consumer unit. I use the continuity function on my Fluke 2 pole tester to do this. This is done whilst the circuit is dead. Prior to this, I am very diligent with the conductors...

    Insulation Resistance Test, trying to wrap my head around it

    I am self-teaching fault-finding and testing, but I can't wrap my head around insulation resistance tests. From my understanding you send 500V for domestics down the conductors using an Multi-Function Tester, and the values should be over 1M Ohm, now my question is why should the resistance be...

    UK Different test results after DB change

    Is it common to get different test results when upgrading a db? Basically I done an EICR in November and came back to upgrade the db and done live tests on all the circuits, but my results were quite different. Like 0.30 ohms out on one circuit
