Wow! This is video very informative and the best tutorial on the topic for me so far. I really appreciate it. Thanks for sharing it with us.

Excellent explanation of insulation resistance testing, and graphics

So useful, thanks

Great graphics! Thank you. IR testing does not give an indication of conductor corrosion or if its ability to conduct electricity is adequate right? Is this test enough to give tenants confidence that main cables powering a house is satisfactory?

Thank you for your guide very important

👍👍

What is the test voltage needed for a 4160 3 phase motor, and what is the minimum acceptable IR for that ?

Thanks very helpfull

Thanks for this very instructional video, well layed out and easy to follow :)

why would 23mA trip a 30mA rcd?

Very interesting, surprised to see arcing of two 1.5v batteries.

Nice graphics what software do you use for that?

Amazingly good instruction

Thank you for your efforts in producing this, it's appreciated. Just like your previous ones, it's very well presented and full of theory and real world content. I'm looking forward to the next episode, hopefully not too long away, as I am keen to see where you're last scenario of false positives etc is going as the AV pictures made me think where you were going. Great production. I've got the 1741+, how do you rate it?

Great content as always. Good to see real life Megger testing clips included. The Dead short? explanation very helpful. I tested my own Dimplex plinth heater last year and now realise that i wasn't getting a dead short after all. Excellent detail for all learners .Look forward to Part 2
