Really good mate. This has really helped to clear up my confusion. I jusr didn’t understand before and now it makes sense. Can’t wait for the next one.
Great video as ever Dave! I like to use the actual fault (eg.. nail in a cable) as the automatic link. Then, after safe isolation and removal of the connections from the consumer unit, set the meter to Ω and go around the circuit looking for the lowest impedance. This then gives you a good starting point of where to start checking for damage to the cable. Looking forward to the next instalment👍👍👍
Hi dave I really appreciated your help very informative and understandable I wish if you were my teacher if you could leave a link for a sockets adaptor link I couldn't find it on line or the shop thanks
Hi, great informative video. I have an extractor fan in the bathroom which sometimes keep going on and off, can someone please tell me if it is short circut or not? Many thanks
Nice lecture. might have been good to show sketch of resistances values and explain why it stays at 0.17 ohms after short just for complete understanding
Tonight I’ve had a short circuit fault even though the IR readings were all over 100M ohms? It’s on a kitchen ring final circuit but not tripping immediately. It can take up to 20-30 mins for it to trip? Any ideas or help is much appreciated. Your video has given me more guidance now which I will definitely bear in mind so thank you
What I used to do was to get as many old questions and answers on anything electrical. Its important that you have access to the model answers. Then I would write out the QUESTION and the ANSWER. Do this for 6 or 10 questions. Throw the pieces of paper away and write out the very same questions and answers again. throw the paper away. Write out the same questions and answers again. repeat until you can write the questions and answers accurately without looking at the question paper. Then do the next 10, write, repeat, write, repeat. Do some every night starting now. If you weakness is physical testing, make yourself a little test board from 2 foot by 4 foot chipboard. A cheap consumer unit and a few sockets and a light or two. Plug it in and test away. Put a fault on it and see what test results you get. swap the wires in a two way switch and see what happens, how to find it etc. put the effort in now and assessment day will be a breeze. Phew! Perhaps I should do a video on making a test board. Good luck. Dave.
Thanks again for sharing your knowledge. Do you have any adcice on how to establish the actual route of a ring final - in other words when the conductors leave socket A how can you establish which is the next socket on the circuit?
Without the installer leaving a plan for the customer it can be difficult. However, if you know it is only a downstairs circuit, it is very likely that the route will follow a ring too. If you can find the furthest socket from the CU, ask yourself, how would I route the cable from the CU to here and how would I get back to the CU from here and take in all the sockets. A mixture of guesswork, practice and lots of luck.
Dave, just trying to get my head around why the socket at B closest to the fault has the highest reading. Is it because the furthest from the failt the lower the resistance reading
As the length of wire increases, the resistance increases. As socket B is closest to the fault, that will be the longest length of wire. Hope this helps.
Friend of mine purchased food/kebab Catering van and guess what he needs EICR but Iv check RUclips to find so video to give me some tips but unfortunately there’s no video or anything, I’m sure if you make an video about catering it would help everyone! Thanks
At 16:25 in video. Would the reading not continue to get larger. I mean you have 2 resistances in parallel, the nail and the short at the socket. The bigger either is the larger the reading ? Of course the resistance of 2 parallel resistors is always less then the smallest resistor but the reading would still get larger ?.. Can you explain further.

Wow! This video is very informative and the best video tutorial on the topic for me so far. I really appreciate it. Thanks for sharing it with us.
Glad it was helpful, spread the word Daniel. Thanks.

Glad it helped, keep watching, lots more to come. Dave.

Great comments, everyone has a preferred method. Working on Part 2 very soon. Dave.
Another excellent video Dave-many thanks-
Glad you enjoyed it David, thank you.
Top man....Top job
Thanks a lot, appreciated. Dave.
Another high quality video. Thank you Dave.
My pleasure, thank you.
I am looking forward to using this method
That's good to know. Try different methods and you will find a method that you like. Thank you. Dave.
Very Educational
Glad it was useful. Dave.
Great video mate👏🏻👏🏻
Glad you enjoyed it and good to see you back. Hope you are well. Dave.
Thank you so much for this great teaching
You are very welcome, thank you.
Rule of Safe isolation: If the circuit is not dead, you might be when you touch it.
Exactly. thanks for watching. Dave.
@@learnelectrics4402 I always look forward to your videos. Am a pro electrician, thanks to you
Hi dave I really appreciated your help very informative and understandable I wish if you were my teacher if you could leave a link for a sockets adaptor link I couldn't find it on line or the shop thanks
Brilliant, thank you, I've got a farm to do this week with a ream of remedial work from someone else's EICR, good stuff to jog the noggin 👍
Have fun, many a happy time working on farms. Dave.
Perfectly explained .👍
Glad you liked it and thank you.
Thank you very much once again. I learnt something new today with the second method. Love it, Appreciated
Great to hear that, appreciated. Dave.
Great job
It is useful and informative
Glad you think so, thank you.

Maybe I could add that on to the series, thank you.
18:24 Dave, it worth watching you always
Thank you, I appreciate your feedback. Dave.

Is the circuit damp, that can often cause a slow trip.
Take a look at this video on earth faults too.

Genius. Any idea where you got the short lead to short out on plug adaptor. Did you make it up yourself

Mobile units such as this are classed as special locations. Refer to Part 7 of the Regs book, section 717.

Of course the resistance of 2 parallel resistors is always less then the smallest resistor but the reading would still get larger ?.. Can you explain further.
I will do another video on this to explain it. Its all to do with very small resistances in parallel.
