Discuss Expected r1 r2 value when circuit 16.5m long in the UK Electrical Forum area at ElectriciansForums.net

That must be why it had an average of about a 60% failure rate.
Doesn't mean a lot, that was down to the entrants not being ready for the exam. Forget the non electricians taking part, but many sat the 2391 to get JIB Appproved status and a pay rise, despite day in day out only doing the likes of containment etc, never coming near to a piece of test equipment
 
It would be a real one from my actual exam, it was a contrevesual year as there more than ave failures. But if you have some past ones anyway, I am sure I don't need to go to the attic and dig mine out :)
