How to test for insulation resistance inside a consumer unit. Marcus is carrying out an electrical inspection and testing when he come across a fault giving him a low reading during the insulation resistance test. These videos will help with AM2, AM2S, AM2E and your apprenticeship end point assessments. The testing and fault finding is carried out with a Megger MFT tester in controlled conditions at Tresham College.
Electrical fault finding
Videos are training aids for City and Guilds (C and G) and EAL courses Level 1, 2, 3 plus AM2, AM2S and AM2E.

The only way you will get practical learning sessions is if you go to college for it.

Electrician mate jobs are scarce in my area and when they do come available they get filled up quickly.

  • Great intuitive videos as usual - keep up the good work - However, getting annoyed with all instructive/educational vids which do not allow for real life / on-site realistic approach/procedures. Does anyone else agree some vids should cover this. Example - Testing insulation resistance (Nobody removes lamps, dimmers, pirs, fluorescent lighting, batteries etc etc, it would take an age. So why not demonstrate test at 250v procedure with L/N connected together and testing them to earth ?? Opinions on this?

  • Here in NZ the megger voltage is around 1000v. Do your regs call for 250v testing ? Interesting to see how regs vary form country to country. Ring ccts are illegal here too.. In order to keep our registration active we are required to do a refresher course every two tears... I mean years.. :) Last refresher I was a week late and I received an email stating I must not do prescribed electrical work even tho I have a spotless track record for the last 40 years. Another interesting fact thats way over the top IMO is if you fit a back to back power point ( or GPO) the 6inches of cable requires to be insulation tested. Insulation testing goes hand in hand with earth loop impedance tests.

  • Hello. I live in a rented property and have been told that I have an insulation resistance fault that was apparently found a couple of years ago and that an electrician will need to visit me. This may be a silly question but my house is quite crowded and all my power-points are behind book shelves with extension leads plugged in. Will he need access to all power-points please? This will be a bit of a task to sort before he arrives. Thanks for anyone who can answer this 🙂

  • Could you clarify? if I was doing a global IR test, and I got a reading of below 2 Meg Ohms, say 1.5 Meg Ohms. Then I would be required to investigate further, and test the individual circuits. And if I found one particular circuit was reading say 1.8 MegOhms then all would be ok as it’s above the minimum of 1 Meg Ohm as stated in bs7671. (assuming it was an eicr and not a new install). So on the test form would I still write the 1.5MegOhms? Being the global reading across the installation as a whole. Or would you write individual circuit ir readings on the form?

    @gbelectricks@gbelectricks3 жыл бұрын

    • It’s the overall insulation resistance of the board to be 1 MegOhm or more not individual circuits. It’s the old resistors in parallel calculation to find the overall resistance. If you had 6 circuit of 200MegOhms and one of 2MegOhms the overall insulation resistance would be less than 2MegOhms. Thanks for commenting and watching. Gaz 🦾
