Helping a friend out. The have lost all lights in the kitchen (around 15) they are 240v led downlights. They also have some under counter lights that have failed.
I've done some basic checks, circuit is love from the DB. Living room lights work and the loop is 240v. There is a feed into the...
A lot of these mock exam questions are not specific about armoured or non armoured multicore cables, flat twin or not etc, the correct table to use can be a bit of trial and error until you get the correct answer for Volt drop for example.
Hey, I'm wondering how to find your 1st ever electrician job. I'm looking to get level 2 and level 3 CG electrician qualification in a college. Every electrician mates job offer often requires a few years experience, so I am confused on how to get your first job as a mate. Whats the best sector...
Is there a way to find XL without knowing the value of the Inductor?
I have a question where R is given as a value of 100v/10A = 10R
It then goes on to say the supply is changed to 100v~(rms) at 20ms (which is 50c/s) and the measured current is 6A. It then asks you to find the "overall...
The track in question is Eutrac single circuit (i think) and the offending fitting is hung from one of these.

There are three pendant fittings on this one particular section of track; the one either side of...
Hi guys (and girls)
Have a job for a long term customer, finding a pretty awkward fault. I'm almost to the point where I'm a bit stumped. Generally speaking IR testing, RCD testing and experience hasn't let me down in the past and I've found plenty of faults other 'electricians' haven't...
Hi all,
Sadly I have to retake the fault finding section of the AM2 next Monday.
We used a multimeter to determine faults.
There are millions of types of fault, however only 4 types of wiring faults are being tested:
Open Circuit = unambiguous/obvious = no ohm reading.
High Resistance =...
Hi
This is my first post on any forum, I’ve been an electrician for 15 years and this fault finding job has got me stumped!
Attended a very old cottage, usual story of fuse blowin at the board. Turns out to be a 6amp 30mA RCBO, the circuit has a fluctuation neutral earth fault on it ranging...
Morning all..
I have a bugger of a ring problem to solve on monday. All the following faults are on the one ring.
It has a N-E IR fault which I have almost found.
It has an intermittant tripping 32A MCB which looks like an overloaded circuit (one ring for whole house) and...
It has a broken...
Hello all, I am currently a site manager for a private school and although I enjoy the job it is only part time and I am looking to start out on a the path as an electrician.
I have the basic electrical knowledge but obviously lack the quals.
2 problems though -:
1) I am 52, so not a spring...
I have a new breaker panel fitted (March), mostly new appliances, and some from an existing house.
The house is divided into 2 sections with an RCD for each, each section has a ring main and lighting as well as a couple of other breakers on it. One of the RCDs trips infrequently time between...
Has anyone got any examples of AM2 fault finding,
MCB trips when calling for hot water?
Will this be hot water valve?
Motor tenant complains of tingling feeling on DOL? Open circuit on CPC?
Hi, did much AM2 a few weeks back and failed on fault finding, the test centre don’t give you much indication what you failed on but rang them up and was pretty close with 4/7 faults and you need 5/7 to pass, the faults I had were these,
Data - just plug in tester
Bonding - open circuit
16A...
Hi don’t do that much fault finding and could do with some help, AM2 7 faults to find using on a continuity tester so can only be one of four things, but not really sure what readings to expect?
Short circuit = tester should show a few ohms but may have some resistance in leads and bleep
Open...
I'm an apprentice and I was going through my college work to do with volt drop and everything I needed to know about the design current was in the question. What I'm confused about is in the real world how you would know this?
Am I right in thinking for arguments sake if I'm supplying an out...
Hi everyone, did some insulation testing on my mates house as his RCD was tripping manage to isolate it to the ring circuit, Live-Earth for the ring circuit came to 0.01Mohms and all appliances have been disconnected and removed.
However I have disconnected the Live-Earth behind one socket...
