    Insulation Resistance Results

    Hi, I’d like some clarification with regards to insulation resistance results I’ve got. Carrying out initial verification on a new ring final circuit. New cable, 9 new MK double sockets. r1 - 0.43 rn - 0.42 r2 - 0.68 R1+R2 - 0.28. Carried out insulation resistance test: L-N - >2000 MOhms L-E...

    Went to quote, discovered recent EICR has fabricated results. How to proceed with client?

    I went to quote for remedial work in a flat yesterday. The client is selling the flat and wants an EICR for the purposes of the sale. The last week they had an NIC electrician who performed an EICR, which they then sent to me. Worth mentioning at this point that a neighbouring flat had caught...

    Commercial Multiple Earth Electrodes Test Results

    I need to clarify something that's rattling around in my head. I was taught when testing lightning protection systems that the maximum permissible combined electrode readings shouldn't be over 10 ohms. So we would test all the electrodes individually then work out resistance in parallel. We...

    Schedule of results when adding to installation

    When adding just a couple of circuits to an existing installation, what exactly do you put on the schedule of results with regards to the old circuits. Just the circuit number and name or do you add the breaker details also like bsen, type, breaking capacity, rating. Obviously can't add ref...

    Weird IR results? At a Switched Fcu in RFC

    So I am doing an insulation resistance test on a new flat and I get a dodgy L-E reading on the IR. I won't go above 20Meg and it fluctuates. Identified where the problem is and its a switched spur. When cables are removed all test +299 including the load which is 2 sockets. When all are put back...

    how should ring cont results relate to R1R2

    Sorry if this has been asked . How should the results or ring continuity relate to r1r2 results. Today I got L-L 0.32 N-N 0.30 E-E 0.56 and my r1r2 was 0.76

    Odd test results on RCD Spur

    Tested an RCD spur earlier with some odd results Tested at x 1/2 (both waveforms) and no trip x 1 (0 degrees = 28.5 ms), (180 degrees = 18.4 ms) x 5 (0 degrees = 8.2 ms), (180 degrees = 40 ms) S0 getting bang on 40ms at x5 on 180 waveform; i know its in...

    EICR Test Results mostly left blank

    Mornin' I did a small job for a client earlier in the week and told her I need to complete a Minor Works cert - as you do.. She said that she didn't need one because she had this - waving an EICR under my nose. Looking through the document, it all looked good until the last page - test results...

    Do neon indicators affect Zs test results?

    I know that having a neon in the circuit screws up IR testing, but I just wondered if the same applies to Zs testing. Many thanks

    Recording PFC and PSCC results

    I have my Am2 this week and am getting confused with what reading is to be placed in schedule of test results. I understand for PFC to take the highest reading between 3 phase and earth but have to then go between phases & N to find PSCC. Is it PSCC reading then doubled and put on back of test...

    recording of earth continuity results for appliances with detachable leads.

    When testing appliances with a detachable IEC power lead, what's the recommendation for recoding the earth continuity value, do you record the higher value including the lead resistance, or exclude the earth resistance of the lead from the actual appliance. This assuming that the lead is tested...

    Installation test following rewire

    I've recently carried out a full rewire of a domestic property which had a supply to a garage by use of an armoured in ducting run underground. I have taken a new feed to the adaptable box that said armoured is terminated into and have tested the armoured itself and all is ok. My question is, as...

    IR connundrum

    Hey Guys I've got a bit of a head scratcher that I was hoping someone could help with. I have a ring main feeding 7 points. When testing IR btw L&N I get 967Mohm but when testing N-E & L-E I get 455Mohm. I split the ring and tested as 2 radials and the results suddenly come back all clear at...

    Earth Leakage Test

    Once asked if a normal Multi Meter could do most of what a PAT tester could (ie saver £££ £350 for the machine an £75 for it to be tested) <Shows how slow i am at recalling things> but some years ago i did 2377-22 and didnt recall it from there. I do own the 3rd Edition Code of Practice for...
