    Global Insulation resistance testing

    I was doing a fuse board update the other day and normally I use duel RCD boards with mcb s but instead I used separate Rcbos due to the customer specifying these. I prefer fitting Rcbos due to just that one circuit is disrupted when there is a fault. when quoting for the job I carry out a...

    Insulation Resistance Testing - necessary ?

    Recently my boss and I were changing a fuse board(old to new). It was a shared house and some of the tenants were out at work and their doors locked. Not knowing what they had plugged in, in their rooms we skipped the Insulation Resistance test. Everything else was tested fine. My question to...

    Insulation resistance testing

    Hi all ran a ring circuit for someone about 6 months ago and when I carried out the insulation test my results were around 250 m ohms for l-n and slightly lower for l-e, anyway didn't think anything of it as we had just plastered all the rooms where the ring circuit went. Returned to the same...

    Insulation Resistance Testing Ring Circuit

    Hello All, I am to install some extra sockets for a customer on a relatively new build. The insulation resistance test. I tested at 250VDC between line conductors connected and earth and obtained a reading of 1.10 ohms (not megaohms) Does this reading seem likely that a piece of equipment...

    Insulation Resistance Testing Problems

    Been to a Job this morning problems with RCD tripping, Global IR came back 0.016, Split circuits down and lighting tested (Including outside tested 0.018) however tested again 0.567 and then 1.03 each time the figure increases until it sits about 1.14. Testing done L&N - cpc and then N-Cpc...

    Insulation resistance testing with no cpc

    When doing a CU change and lights have no cpc. Every room has class 2 dimmers and lights. ceilings are like 20 foot tall. How would you guys go about Insulation testing? L&n to cpc ain't an option and removing all lights and bypassing dimmers is consequently going to take some time... What would...

    Insulation resistance testing

    Hi guys, I obviously know how to conduct a IR test but I'm just looking for a few tips, I was doing a lighting d\b today and obviously I never did a L-N test as it was a massive building and not feasible to disconnect all lamps. It was a triple pole +N mainswitch so I isolated the board, it is...

    Insulation Resistance Testing : Can someone proofread the below for me please ?

    Title says it all really. I've just qualified and unfortunately my college bombed through IR testing but before I even touch anything I want to make sure I understand it thoroughly. Can anyone please compare what I've copied and pasted below to the diagrams and made sure I've understood it...

    3 Phase Motor - Insulation Resistance Testing

    Hi all, Could someone please help with a query I have? At a factory I work in, we get a lot of damaged motors (due to it being a very wet environment), they are only quite small normally, varying around the 0.25-0.37kW size. Normally when I test them, I remove everything so I am left with the...

    insulation resistance testing stanless steel

    in a cafe at present working and is a load of stainless steel in one corner for washing up etc.. i want to do a test to see if needs bonding im nearly certain i I r test from earth isco to stainless steel in question and test @ 500vdc and if under 22k ohms it should be bonded, is this info...

    Insulation Resistance testing - again!

    Hi Getting used to Metrel tester and am getting used to testing and was just after advice on clarifying some points: 1 - FCU's with neon indicators on IR tests - whats the best way of disconnecting the neon lights on these if they cant be disconnected? Do I keep that particular FCU switched...

    Insulation Resistance Testing Fluorescent Lights Etc

    The large domestic garage that I wish to test has a single lighting circuit with 6 fluorescent lamps inside and a floodlight with a PIR. It also has neons on each of the 2 way switches for the internal lighting and a neon on the switch for the outside floodlight with PIR. Any tips on how to go...

    Insulation Resistance Testing (Whole board at the same time).

    Lads, I am soon to be doing an EICR on a large working mens club (not being paid in ale). My question is this...There is going to be lots of lamps i cant take out,equiptment still plugged in that i cant find etc etc so im gonna have to test between L-N to E . When carrying out the IR test at...

    Insulation resistance testing - combined L & N test

    Good Morning all, When you are doing the combined L&N to earth test on a circuit that contains vulnerable items, do you record the result in all 3 columns ? And do you have to mark the results that you have done the combined test? Thanks

    Insulation Resistance Testing - Gremlins!

    How close have you come to losing the plot on site? lol I'm normally quite laid back when it comes to working my way through the faults that I have come across in my limited testing time. Today though? Oh my flipping ruddy bollards!!! I quite easily could have lost it completely ha ha...

    Insulation resistance testing on sensitive equipment

    When doing an insulation resistance test on selv spots what's the best way to do it without disconnecting all the transformers? Can you do a complete consumer unit insulation resistance test by linking the live and neutral bars together and testing between earth on a 500 volt test or should...

    Insulation Resistance testing of Emergency Lighting circuits

    This is proving to be a pain in the backside. It just impractical to disconnect the emergency, as they are hard wired. So apart from putting notes on the test sheets, how can I get good readings, at present I am getting 100 ohms on all conductors, with emergency connected. When the emergency's...

    Query regarding insulation resistance testing

    Everything I have read so far about 'Insulation Resistance' testing only ever mentions 3 procedures: Line - Neutral Line - CPC CPC - Neutral But on the 'Minor Works' cert the first test it specifies, in the part pertaining to insulation resistance testing, is: Line - Line I've got the...
