    Incoming cable - earth neutral continuity!

    Just spent a frustrating day fault finding and still left scratching my head, was wondering if anyone else had experienced something similar! The kitchen we had been working in had been a proper DIY job (diagonal cable chases, no earth sleeving etc etc etc) so we were testing a ring circuit to...

    ring testing

    whilst doing ring continuity i have no end to end on cpc also on isulation test live earth im getting 9.50Meg ohmson the same ring are these two results to do with the same problem if so how can i go about finding the fault am i right in saying that if i spilt the ring at one of the sockets then...

    continuity on ring main

    Hi. be nice for some feed back on this. I'm testing a ring main for an eicr. I know that the cpc reading should be around the 1.6 times higher than the live conductors but I'm getting 0.66 on live, 0.67 on neutral and 0.61 on cpc. I'm wondering, if the cpc are connected through the metal k.o box...

    240v but no continuity

    Hi, Just went round to a customer who wants the ring extended in the garage, Prelim checks found no continuity on live, OK on E&N. When power is on 240V on each leg. Will go back and look further, customer said everything was unplugged but thought I would ask if anyone had come across this...

    Concealed bonding conductors

    Morning all. I'm about to set off to a cellar conversion. The gas, water and electric incomers are all in opposite corners of the cellar. In the next few days it's all going to be plasterboarded, which will conceal the bonding conductors permanently, although the actual earth clamps (i.e. the...

    Some help for course work info needed

    Hi there, I am new on here,Great place ! Can someone explain to me how to do an earth continuity test and earth loop test on an electric cooker where the cooker point is already installed. Our college tutor has asked us to find out the info for next weeks lesson ,where we will be asked...

    Weird continuity results on ring

    Strange test results on an old ring: L-L 0.14 ohms N-N 0.15 ohms E-E 1.12 ohms L-N (this is where it gets weird): 1st d/skt 0.07 ohms 2nd d/skt 0.08 ohms 3rd d/skt 0.21 ohms 4th d/skt 0.36 ohms 5th s/skt 48 ohms! 6th d/skt 48 ohms! 7th d/skt 48 ohms! Spur d/skt 48 ohms! WTF!? This was the...

    Voltage / Continuity Testers - feedback required

    Noon all , I need a new set of Voltage / Continuity test probes and was wondering if anyone has had probs with their testers tripping out rcd's / rcbo's whilst measuring voltage ?? If so please name and shame so i can avoid. Any other input on whats good or bad is also welcome. Quite like...

    No Earth Continuity on Ring Circuit

    HI all.. Some advice please if possible, i did see a post on here which related to this a few days ago when i first joined, i cant seem to find it now. ON testing earth continuity on a upstairs ring circuit i get zilch, nothing, zero!!! Both L's are good and come back with the same reading for...

    Puzzling IR & Continuity results on an old Ring Main

    Hi, I'm relatively new to this forum and have not long since qualified. As one of my first job, I recently installed a new CU to feed a large shed. I got the clients provider out to install a service switch so I could safely tail up the new CU. Whilst the engineer was out he plugged his tester...

    what is the MOST likely cause of high resistance when testing continuity of cpc

    hi guys, what is the MOST likely cause of high resistance when testing continuity of cpc? I know likely reasons could be loose terminations, bad terminations (e.g not all wiring strands in connection), dirty connectings, ect But what would you say is the MOST likely reason for the high...

    best practice continuity

    If doing end to end continuity testing on a radial circuit (2391 test board) is there a requirement to carry out R1+R2 as well, and if so what does it prove? I carried out end to end on the board today as some of the circuit used armour as CPC etc and I was told I should have tested R1+ R2 as...

    how to test continuity if?

    hi, how would we test contunity of the CPC if we were using SWA and using one of the SWA cores as the CPC? would we simply do a contunity test from each end of the cpc cable

    Question regarding Continuity of Ring Final circuit.

    Can we carry out the continuity test for the ring final by connecting the line, neutral, and cpc end to end at any socket or do we have to identify and disconnect the conductors at the C/U? I am aksing as i think it is much easier to link the line, neutral, and cpc end to end at any socket...
