I would be interested to know which test method was used. Did he do conductor to conductor, in which case it will see the connected loads, or did he do Lives joined together to CPC, in which case it would eliminate the loads and give a more accurate reading. I would also be interested to know if...

The new written exam comes as part of the candidate assessment pack which is downloaded by the centre. The Chief Examiner is no longer involved as it is now marked in centre by the assessor, the quality of this will be monitored at annual EV visit from C&G. You are right about previous exams...

Evening all, I am new to this forum, and have made a few contributions, and had a good look around. I dont want to reply to old threads so i have started a new one about the new qualification I taught the old 2391, then the 2394 and 5, and have now started with the all new 2391, so here is an...

I teach this stuff, and your explanation of Periodic Inspection and testing is by far the best explanation i have ever read about the subject, would you mind if i nick it? Locked to prevent being resurrected (again)

Dont know if you have resolved your problem, but, if you have R1+R2 value of 0.12 and a Ze of 0.40, then your Zs cant be any higher than 0.52. maths dont lie. You say that you have 2 circuits giving you a reading of 1.22, you are highly unlikely to get 2 identical results unless you have 2...

Good point, and one that i have not considered even though i teach I&T. The easiest solution i can think of would be to join both of the live (L and N) conductors together and insulation resistance test at the usual 500v between them and the CPC, like you would do for a lighting circuit with...

To say that replacing lost certs is a ****** it is the understatement of the year. I can back up your comments wholeheartedly.

You could utilise what you have put together and do some dead tests for a bit of practice. Add some resistors to your ring circuit, put one in series on each conductor on the circuit, power resistors will be better because you could insulation resistance test the circuit and eventually move onto...

No, things have moved on and changed over the last few years. Get the latest GN3 and download the free GS38. Study them and get your head around basic electrical theories like OHMS law, and insulation resistance theory and you wont go far wrong. Murdoch, most will opt for 2391-52 and this will...

2394 and 2395 replaced the old 2391-10 back in 2012. It followed the same format but entailed more exams, 1 multiguess and 1 each for initial and periodic, but i guess you all know that anyway. C&G are/were losing business to EAL. EAL have always been open book, so they aligned with them...

Hopefully, and i fully agree. I am here to help, if anyone is in need of an insight into the new 2391 qualification, or wants some general advice about it all, then feel free to ask. I dont profess to know everything about I&T, but what i dont know i can find out. What i wont do is...

I have been away from forums for a few years but have now decided to make a come back. I am an Electrical Engineering Assessor for NVQ3 and a Tutor for BS7671 and the new 2391 qualifications.
