    Good day The following table shows the results of 3 current transformers (50A/5A, Class 0.5%) connected to a 3P-4Wire Digital Energy meter. (Performed at the meter manufacturer's workshop). It is observed that at Unity PF, the meter readings for current are a close match to the supplied test...

    EICR test failed due to no RCD on smoke detector, lighting, door bell, security alarm

    Hi, I recently did an EICR test on my flat built in 2008. The engineer was in my flat for less than 10 mins, he was asking me irrelevant questions as in whether I am renting and that is interested to rent.

    Difference between 250v/500v insulation resistance and 15ma/200ma continuity test?

    R2 test without removing cover

    Hi all when performing an r2 test prior to commencing an EFLI test would it be acceptable if the board was made from metal of course to test from the point to the outside of the board rather than to the earth bar? Just for when you are working with large 3phase boards full of cables.

    Hi all, im aware of the test needed to be done when trying to find out if a metallic object is an extraneous conductive part but for example, if you had a copper water supply system in a house that is fed with a plastic incomer pipe out the ground you will always receive a low resistance reading...

    Why does a fridge freezer fail an insulation Pat test?

    Hi, I am getting a reading of 0.00MOhm I've never had this before, it's not tripping the rcd. I was wondering if it may be damp but can't see anything obvious. Any ideas please? It's not very old.

    Had an interesting one today, ring circuit blown the Mcb in a kitchen apparently a few times over last day or so. It has blown once when nothing was really in use in kitchen so kind of ruling out overload. When turned up and turned it back on it held for maybe 5 minutes before blowing again…...
