Very good explanation of the insulation test. 👏👏. I didn't realise the KT66 had a DAR and PI function for the IR, first time I have seen an MFT with that.
How about ir testing a floor of a multistorey building with other live floors in operation with common risers with ventilation ductwork, copper water pipes , air conditioning copper all bonded from the other floors???
Another great video 👍. What effect on the readings does testing at 250v have rather than 500v ?, ie if tested at 500v and got say 300 or 400ohms would you expect it to be half ?. Still learning cheers
On a good installation, then testing at 250V or 500V should have a negligible effect on the reading. If you have a fault in the insulation or it is damp etc, then increasing the test voltage will likely give a lower reading. That effect will be exaggerated if you step it up to 1000V. The only thing to be aware of is that some circuits get charged by an insulation test. If you carry out multiple IR tests on this type of circuit in quick succession, then you may get a higher reading as the following test just builds up the charge created by the previous test. For these circuits you have to ensure that they are discharged between tests.
@@three-phase562 thanks for replies appreciated 👍. So testing at 500v or 250v results on a said circuit should be about the same results. Was just curious due to the lower test voltage. Thanks again for doing the vids 👍
Please sir i need to know where can i get that book you are showing regulations and pictures from, is it the BS requirements for electrical installations for UK? 2018? 2022 ? where can i find it?
I wish I had this when I was starting out man. So clear 👏🏼👏🏼👏🏼
Test between L-N together & E at 250v anything above 4meg ohms happy days, simples 👍

Cracking video. Even as an experienced spark it was informative and had all the info needed. Keep up the good work mate!
Some great information there Mike. What every happened to the lampost issue shown at 10:34 ? Was it water ingress or damp or something else?
My favorite tool for fault finding is the toner
One thing I've found for fault finding by using an analog IR tester you can see fluctuations much easier than a digital display.
Will smoke alarms (obviously mains) or something like a cooker or hob get damaged when testing at 500v?

Good video as always Mike. Very interesting. I see your using a few Dewalt tools now you cheating on Milwaukee 😂
Great video bro! Hope your enjoying the new meters as much as I am 😎👌⚡️
Hi Mike,
A very comprehensive and informative video on IR testing! Catch you on the next one!
Stay safe, keep well. ⚡️👍🙏🏼
M8. Another banging video 👍. Thanks.

I'd be slightly worried if I got 300 of 400ohms.

Pushing loads of your videos to my apprentice 👍🏻👍🏻
Recently bought the boddingtons cable knife from loadout. Arrived on time. Superb service mate.
when will the veto pro tech pac blackout bags be back in stock?
Can you do a video of your metal munching bag mate
Fantastic video, Mike. I just passed my 2392 practical and theory test after this video. I'll encourage anyone to watch.
Thats what its all about mate, congrats!
Thank you. Great video
Would you be doing a polarity one?
Please sir i need to know where can i get that book you are showing regulations and pictures from, is it the BS requirements for electrical installations for UK? 2018? 2022 ? where can i find it?
I need the one showing methods of testing and pictures, the one that you have its very important for me thanks.
@@ionutth4895 The book is (GN3) Guidance note 3 latest edition is yellow cover with brown strip at bottom
Love these!
👍👍👍👍👍
