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

    Hi I hope everyone is all well. I’ve built a rig at home on some ply to do some testing and fault finding to prepare for my exam and just learn in general… I put 100v then 250v through L & N through a B22 led lamp and also the spur neon to see what reading I would get. They were both the same...

    EICR Failed - Open circuit / No continuity

    Hi, I had an EICR done and it failed on one item which was a C2 and that was in our utility room. From what I was told there is an open circuit and no continuity. It took a long while but after questions asked, it was ascertained that the previous owner had an old boiler in the utility room...

    What do I search for on Amazon: WIFI continuity Switch No current, no load

    I have a bathroom fan with a moisture detector that turns it on and off. It also has a control circuit to turn it on/off when moisture is not connected. This is a no voltage/no current circuit. I want to add a parallel control circuit that would of course be no load no current that I can turn...

    Cpc no continuity on pendants

    EICR picked up no continuity on cpc on 3 pendants fittings in a grd Floor Flat. Zs measured @ other pendants & complies. Different opinions on the coding personally a C2 for me..but others are saying C3 mainly because of the code guidance in code breakers. I think this statement relates to no...

    Voltage and Continuity Tester Recommendations

    Hi all, Firstly I am new to the forum, so will start by saying hi. I work as an electricians mate, and am joining the forum to gain experience. I am looking to purchase a decent voltage and continuity tester that complies with GS38. The two I have considered so far are the Kewtech KT1780 and...

    Continuity where you would not expect continuity!

    I am wiring up a new kitchen and conservatory. I'm not sure why I checked continuity between line and the metal back box of the light switch, but I did. I haven't even finished the first fix and the metal back box does not have an earth connected to it yet. The voltage tester (on resistance...

    Continuity values keeps going down.

    So bought a second hand Megger BM233 to practice with as I'm a college student.. So I was just using it on a loose 2.5 cable. Testing on the neutral from both sides . Whilst having the device on the Ohm side. I nulled it to zero by touching the probes. When I do the dead test. It starts off...

    Megger MIT420/2 unstable continuity readings?

    Chaps - having problems with a new Megger MIT420/2 insulation/continuity tester 'oscillating' and failing to give stable resistance readings in continuity mode with some motors (although it did it once on a Cal Card!). I don't think it's a duff unit, but anyone else have one and experienced...

    Continuity / Ohms testing help / Short ?

    Hi, I would love some help understanding an issue I’m having on a 16mm SWA cable running from the CU in my house to the CU in the shed. I believe there is a problem with the cable (possibly between E and N), and I have used a multi-meter to do some checks on the CU (shed side) and below you will...

    Cheap Voltage and continuity tester?

    Hey guys I am still studying in college. I just need one to play around with. As I will be making my own boards at home. Can anyone recommend me one to use ? So I can start practicing how to do testing. Thanks

    Earth to Neutral Continuity - Advice Needed

    Hi all. Reasonably competant non electrical engineer homeowner here. I have a question for the experts: I recently replaced a horrible above-ceiling downlight connection with a proper Hager junction box. Whilst checking things generally I found my multimeter was reading a continuity between...

    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...

    Contactors lost continuity

    What could be the reason for all of the three Siemens contactors on a 37kW star delta starter to lose continuity on auxiliary contacts and main contacts all at once? Probably the best thing to do is to replace them since cleaning would be too fiddly. There are no signs of water intrusion only...

    continuity test on a protective bonding conductor

    Hope i find someone who can help me with this one. I have this question on an exam: A continuity test on a protective bonding conductor gives a result of 15ohms. What possible reasons for the result and what actions (if any) that should be taken? My answers where: -wrong size conductor shows...

    Low earth resistance continuity test

    I’ve just carried out a continuity test on a rfc. And I’m getting a lower earth resistance Reading than the reading on both the live and neutral wires. its a circuit in a house converted into two flats and the circuit is wired in 2.5/1.5 twin and earth. Live and neutral are both 0.46 earth is...

    R1,R2,Rn versus r1,r2,rn continuity readings on EICR.

    Looking at the EICR form. GENERIC SCHEDULE OF TEST RESULTS Looking for clarification on R1,R2,Rn versus r1,r2,rn continuity values. I have reached the some conclusions. Do r1,r2 and rn only apply to ring circuits and R1,R2 and Rn (not on form) to radial? It just looks like that might be the...

    TP & N Continuity & Polarity

    Just practicing for my AM2. When testing a 3P and N socket, as I understand, R1 to R2 is CPC to any live (L1, L2, L3) to prove continuity, but how do you prove polarity?

    Cheap Continuity tester?

    What values of resister and led would work in series with a cheap tone generator, and a 9V? Only needed to check unpowered wiring circuits for shorts.

    Best way to check continuity of cpc for lighting

    20 y old lighting circuit with cpc at the board but terminating into class 2 recessed down light fittings. Looks like there is a junction box in the ceiling void feeding the light with L&N but I can't access the junction box so not sure how can prove continuity of the circuit?
