Are you a trainee, electrician or a DIYer as your profile is a little sparse.Fault finding on ring final, is this the readings you would expect to achieve and are these the correct way to find them thanks

3rd year apprentice don’t do much fault findingAre you a trainee, electrician or a DIYer as your profile is a little sparse.
Then to aid us in helping perhaps you could update your profile and avoid unnecessarily obtuse answers.3rd year apprentice don’t do much fault finding
3rd year apprentice don’t do much fault finding
I'm guessing here but my guess he is his employerYou need to raise this with your employer ....... Fault finding is a key skill, learnt on the job, from others .....

Well what's your take, the OP Could be doing a private job.Are you suggesting the apprentice is the boss?
Have you looked at the video yet? that should help know end, not much of a Boss if you feel you can't ask him a question, decent people won't mind answering a legitimate question. Where are you based? Sorry missed that London too far for me to come and help you out.I don’t fault find at work so pointless asking my boss and it’s for AM2 in few weeks and college have too many people to bother about showing me
Yes I’ve watched it, just wanted to know as in AM2 your only allowed continuity tester so all faults are wiring it’s just the same as dead testing just wanted to know if my drawings was correctHave you looked at the video yet? that should help know end, not much of a Boss if you feel you can't ask him a question, decent people won't mind answering a legitimate question.

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,Pete's approach above is the best one, it will catch most faults, but as you only have a continuity tester:
Reverse polarity:
Normally easiest to find by inspection.
Assuming you have correct end to end resistance results, Joining two poles at the board one of which is not the expected reversed polarity and testing at the socket fronts should give one socket with OL result all others should be very low resistance.
Your diagram and method will work.
Open circuit:
discovered by end to end testing, join one non continuous core to a continuous core and test between the cores at each socket, when you get OL result this is where the fault exists (or the socket beforehand on the outgoing core).
Your diagram and method will work so long as only one leg is joined.
High resistance:
Similar method to open circuit but where the resistance rises is where the fault is (or the socket before hand).
Your diagram and method will work.
Short circuit:
testing between disconnected cores at board the low resistance reading indicates the faulty cores, break the ring down half and half again testing each time between the faulty cores until the fault is narrowed down.
Your diagram and method will not work. only the bit about breaking the ring applies, adding another short circuit to the circuit will not help.
Thanks that’s my problem cause I don’t do much fault finding I just over think itdon'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.
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 instructionsThanks 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
Thanks I’ve done build today have 1 circuit left and then testing and then fault finding either tomorrow or wednesdayBradley 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.
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.).. Fault finding is a key skill, learnt on the job, from others .....
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 itI 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.
Cheers I’ll get it next timeBad luck Mate sorry to hear you failed
Why not?.....that's the fault.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.

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 polarityWhy not?.....that's the fault.
Good luckCheers I’ll get it next time
No idea my fault was on intermediate lights was the lights wasn’t working as a intermediate should and the fault was no continuity between of the strappers on the last switchIf 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!
So, was it incorrectly connected, a faulty switch connection or a damaged/broken conductor?No idea my fault was on intermediate lights was the lights wasn’t working as a intermediate should and the fault was no continuity between of the strappers on the last switch

Open circuit so broken conductor between one of the strappers making incorrectly functionSo, was it incorrectly connected, a faulty switch connection or a damaged/broken conductor?
It'd be useful for a house basher, that....millions of fault possibilities, some, I'm sure, completely unheard of, even by the boffins.Bold statements in here, not that it would really help ....
Are you here advertising?
Feels like playing with switches ..with an audiance !Open circuit ..... strappers making incorrectly function
