    Loop holes

    I emailed City and Guilds asking did NICEIC check peoples qualifications with them "You would need to check with the NICEIC on what checks they do before they issue a license to trade. Our certificates are not a license to trade, just to show you have the knowledge and have completed and...

    Loop tests and RCD's

    Had an old Fluke for years, which has incidentally been faultless . Company purchased a Megger last year however when doing Internal earth fault loop impedance readings are far higher than expected. I.e..example Ze = 0.20ohms r1 + r2 = 0.15ohms Zs should be about 0.35ohms however coming...

    Checking loop tester readings from a sample socket.

    After calibration of my loop tester,I am considering using a socket in the house for future calibration checks and to connect various low resistances in series with earth via a rotary switch to give a range of readings,and if so what value of resistors?Thanks for any advice...

    Earth fault loop impedance

    How does earth fault loop impedance and disconnect time requirements change for 3phase 3 wire 230 volt systems where the phase to earth voltage is 133 volts instead of 230 volts?

    1 way 2 gang switch operating two lights on dimmer, whole flat lighting loop.

    I have taken out ceiling fans and replaced with chandelier lights wired the same but switch will not work, the l (red) is jumped from L1-L1, and black wire I'm guessing is common, the live goes to first light where I have the three Red cables hooked together, the black from switch goes to brown...

    Loop in at switch (Trainee)

    Yeah, this is my first post to this forum. I have been learning the trade for roughly about 8months now, and really only been doing 1st fix to new builds. Now I have been moved to doing 2nd fix, and the problem i'm having is with some on the switches having 6 cables in there. As all the loop...

    Loop method using Fluke 1653

    Hi all! I tried to measure earth resistance by loop method using fluke 1653 at MR system (TN) in hospital. But got abnormal results. The primary (upper) display showed 0.16 - 0.2 (loop impedance) and secondary - 0.0 - 0.1 (earth resistance) Is there some limitations using this method? Cant find...

    loop impedance tester

    Another question - :smile5: When did the use of loop impedance testers first come about? I tried to google it , but cannot find a definite answer, came up with an LCR meter though? So how would you know the Ze before they came freely available and I guess affordable - just by enquiry at...

    Video loop on usb stick

    I've got a customer with a hairdressers, she wants a flat screen installing on a wall, ok fine. She wants a promo video running to showcase her work, is it possible to upload something to a usb stick and have it running on a loop, I suggested perhaps a DVD with the footage on. Any thoughts.

    Three plate & loop in methods

    Hi, I'm an electrical apprentice and wanted to know why the loop in method is preferable in industrial applications to the three plate method. I've learnt these methods at college but it seems that people at work think they're the same thing. Thanks

    loop impedance on lighting circuit

    Hi everone,I am new to the forum and think its brilliant,I am currently studying for my 2394&2395 and am testing everything in sight with a fluke 1651 multi functional tester.When i try to do a loop test on a lighting circuit,I follow all the instuctions,but i keep getting >2000 ohms,i am...

    Light switch two gang, loop through

    Hi, I had an electrician rewire my flat and he never finished. In the lounge I have a 2 Gang Switch, one for the ceiling light and the other for the 5amp table lights. I have two T+E cables running down to the switch. I was told to bridge the Coms to create power for the 5amp circuit. I want to...

    Urgent - Earth Fault Loop Paths

    Good morning, I'm wondering if someone could help with explaining EARTH FAULT LOOP PATHS in a competent way for TT, TN-S, TN-C-S systems. I can draw them on a diagram however find it difficult to explain things. I'm currently doing a HND in Electrical Engineering and unfortunately have poor...

    Fluke 1651B low current loop test problems

    Hi all, Recently, when needing to test earth fault loop impedance on a circuit with a RCBO/RCD my tester just reads >2000 for evert test, even when I know the R1+R2 and Ze are fine and when added together would be well within limits. Is there something I can do to fix this or is it time for a...

    Loop test

    I encountered a strange one the other day, new armoured supply to a shed, Ze at the Rcd main switch in the shed was 0.40, R1+R2 was 0.24 on the supply armour. When I did a earth loop on one if the sockets I got 1.09 which was high considering the run so I did a no trip test on the outgoing...

    Loop test

    136.4 ohms at lights whilst doing the loop test before we change the board. Guessing they've been lucky ? Plus side is I get to put an earth stake in were see how much I remeber from the one I did 2 years ago
