Fault finding on ring final circuit

[Bradley6969]

Fault finding on ring final, is this the readings you would expect to achieve and are these the correct way to find them thanks

don't over think. thast's a major problem.

a ring is just that. . 3 pieces of wire. you have 3 bits of wire with both ends at the CU. end 1 should connect to end 2, and not connect to the others. sssssimplesss.

Thanks that’s my problem cause I don’t do much fault finding I just over think it

I had a NICEIC book once upon a time all about fault finding and solutions to identify and solve the faults etc... not sure what happened to it???? but it was very useful when i started out. i bought it at a carboot for hardly anything and paid for itself many times over... Anybody know if the NICEIC are still making upto date versions of the little help books?

Thanks so open circuit connect at board end eg. L+N then test at socket between L+N if I get reading OL then open circuit or can do end to end on each socket eg test L to L from socket 1 to 2,
Short circuit, so break ring in half then test end to end at each socket no r1+r2 as this is just adding another short circuit

No such animal as r1+r2 It's R1+R2 which is the figure of 8 reading after you have done end to end r1,r2 and rn and inter connected the conductors as per the video instructions

Bradley if your doing your AM2 my only advice is if you locate a fault but don’t think it could be that simple don’t panic or over think things. One of the faults we had thrown at us was a blown lamp on a lighting circuit. And yes you couldn’t remove said lamp to test it properly. I will have a look through some of my books to see if they have pics and easy explanations for you.

Thanks I’ve done build today have 1 circuit left and then testing and then fault finding either tomorrow or wednesday

.. Fault finding is a key skill, learnt on the job, from others .....

Welcome to the 21st century, where real-world simulation software can train and test you on electrical troubleshooting (Fault finding) by creating so many simulated faults for you to troubleshoot, it would take you literally years to gain that experience OJT. (Our mother company sells the electrical troubleshooting training and testing software series.)

I find it is easiest to break the ring in the middle and also at the board. You are then left with two radial circuits, easier to work with.

Yeah that’s what I did I passed everything else but failed fault finding when I was doing ring I was looking for either cross polarity or open or short circuit and believe it or not the fault was a high resistance took me ages to find it

Bad luck Mate sorry to hear you failed

Cheers I’ll get it next time

Why not?.....that's the fault.

Possibly on the old AM2 on the new one there all wiring faults which you’ve got to prove either short circuit, open circuit, high resistance, cross polarity

Good luck

If a lamp has blown you'll get no difference to any readings, L and N are clear anyway. Are you testing each switch circuit to see if lamps are OK?.....so basic it's weird!
