I'm currently just getting into the UPS industry after 5 years of being a grounds worker. needless to say after such a long time not having to do any serious critical thinking in my last job it has been quite the ride trying to learn even the basics of electricity. I was told I will be doing my 18th edition next year and am currently watching your videos to help men get an idea of what the exam will be like and can I just say you do a fantastic job at helping someone like me who has ADHD start to understand what it is I need to know. I can't believe stuff like this is free!! I just want to say thank you for doing what you do!

[@learnelectrics4402]

Thanks for the great comments, appreciated. If you search for Amendment 2 on the LearnElectrics channel you will get all the 18th edition videos that go with the brown book, the one you will take your exam against, including lots of questions and answers for you to have a go at. Lots more to come on this, when I get my voice back. Watching the blue book videos is still good, lots of help on how to search the book. Example Amendment 2 video below. Good luck, its a great trade, and the roof is usually on when you are working! kzbin.info/www/bejne/a3vLoIiNp62csNk

Absolutely love your videos, your teaching skills are amazing.

[@learnelectrics4402]

Thank you, I really appreciate your comment. Dave.

[@sparkyhobo3844]

Excellent , clear concise detailed (but not over complicated).

[@learnelectrics4402]

Thanks for the comments, that's exactly what I wanted to achieve with these videos. Thanks for watching. Dave.

[@dannynash2764]

Thanks for this, clear understanding of how to figure the calculations now.

[@learnelectrics4402]

You are welcome Danny, glad it was helpful. Dave.

Thanks for watching.

[@THECARKUS]

Again, sincere thanks for this excellent content.

[@learnelectrics4402]

Thank you for watching Mark. Many more videos in the pipeline. Dave.

[@Nevster99]

Great Video as always and learning a great deal, only thing on this video, is where to actually find the volt drop and maximum length formulas in the regs, anyone with any pointers much appreciated. 👍

[@learnelectrics4402]

The formula is not shown in the regs. It is talked about over several paragraphs, but nothing like a formula is shown.

[@chelsea08FC]

Really good teaching. Your the best 👌🏾

[@learnelectrics4402]

Thank you, great comments, really appreciated. Dave.

[@johnsonaranmula4320]

Very good video. Very useful Q no1: 5.3v Q no 2: 66 meter

[@learnelectrics4402]

Correct, well done. Have you tried the questions at the end of this weeks 18th Edition video? Five questions to have a go at. Link below. Good luck, thanks for watching. Dave. kzbin.info/www/bejne/pZmqiKqFeZh1ic0

[@basharatpir2487]

Good explanation on voltage drop calculation. excellent work well done and keep it up

[@learnelectrics4402]

Thanks a lot, appreciated. Dave.

[@danielteyehuago1633]

Wow! This is very informative, thanks for sharing it with us. It worth it and the best tutorial on the topic for me...dl

[@learnelectrics4402]

Thank you Daniel.

[@markadams3746]

Wow another great video thanks again

[@learnelectrics4402]

Thanks Mark. If you go to LearElectrics.com and put Amendment 2 into the search box, you will get a list of videos with a direct link to YT on the latest exam with questions and answers, the brown book. thanks for watching.

[@krazylad84]

as always brilliant video , thanks !

[@learnelectrics4402]

Thanks. Great feedback, happy you enjoyed it. Dave.

[@mb-electricalservices]

Cheers Dave. Good stuff as usual. 👌

[@learnelectrics4402]

Thank you Mike, we try to please.

[@musangobi2079]

I appreciate your effort, keep it up

[@learnelectrics4402]

Thank you Musa, great feedback. Dave.

[@AntonyoKnight]

06:18, I am wondering where is the actual formula in the Wiring regulation book. Can you help me?

[@learnelectrics4402]

It isn't. That's why I tell you what it is. It is in the on-site guide, look in the index for voltage drop calculation. And yes, you will get questions on it in the 18th Exam. Thanks for asking, thanks for watching. Dave.

[@yiuyamchi6039]

Very good video , thank

[@learnelectrics4402]

Glad you found it useful. Thanks for watching.

[@56jmack]

Excellent video as usual, can you please do one in the future on insulation tests on boards with rcbos, I have asked several people and got several different answers, Thanks, keep up the great work

[@learnelectrics4402]

Thanks for the positive feedback and the suggestion. It's now on the list and we will do it. Dave.

[@edh4808]

Once again, great channel, can you do a detailed three phase calc? I.e. voltage drop when there are different run and grouping methods, so 100m underground, then 100m on tray, with differing grouping? Do you have to account for these or typically use the worst case scenario?

[@learnelectrics4402]

We will do Ed. But generally you calculate and size the cable for the worst case scenario. If a new length is added and the cable conditions have changed then resize cable/re-fuse etc. Which is what we do in distribution boards. Thanks for asking.

[@basharatpir2487]

do you have website where all these videos are available

[@learnelectrics4402]

Yes, the info is at the end of the video. Go to our LearnElectrics.com website and they are all listed. Use the search box and you will get a link direct to the video. Dave.

[@alextaramsari]

Thanks Dave!!!

[@learnelectrics4402]

You are very welcome Alizera. Thanks for the feedback. Dave.

[@basharatpir2487]

Have you compiled all your videos in one DVD if yes then what is price for that.

[@learnelectrics4402]

I haven't Basharat, it is a good idea though. Thanks. Dave.

[@basharatpir2487]

could you please add voltage drop calculation for three phase circuit.

[@learnelectrics4402]

It's on the list of videos to be done. Thanks. Dave.

[@lllCANDYMAANlll]

Which regs state these formulas? i have them in my notes but I have been told you cant have anything written in your notes, so now i have to stick it note these pages for the exam.

[@learnelectrics4402]

The actual formula is NOT in the brown Regs book that you can take into the exam. It is explained on page 429 and the rest is up to memory. Do lots of example calculations. If you go to LearenElectrics.com and put Amendment 2 into the search bar you will get 18th Edition Questions and help for the latest exam. Good luck, Dave.

[@lllCANDYMAANlll]

@@learnelectrics4402 Thank YOU! again Dave. im on your site now. Much appreciated!

[@lllCANDYMAANlll]

the site is down atm?

[@malachygallagher4936]

Hi How can I find the length of a roll of cable that’s has been used if I only have my meter to measure resistance R1+R2 & don’t have any other formulas to hand? Regards mg.

[@learnelectrics4402]

Malachy, have a look at this video and use the table in the video to help. Just treat the roll of cable as being r1 and r2. Connect the Line and Earth where they come through the reel and measure at the other end. Dave. kzbin.info/www/bejne/b3WvmIBurLJortE

[@malachygallagher4936]

@@learnelectrics4402 Hi Dave! I have watched video before !! It’s very good as usual! Explains all in black & white!! Thanks Malachy.

[@vasilios.v]

What about Voltage drop if you have multiple Consumer units and the one feed the other until the final circuit??

[@learnelectrics4402]

The furthest point of use should not have more than the permitted volts drop. You may have to increase cable sizes that feed the daisy chained consumer units to achieve this. Or, good practice, consider feeding each CU independently. Hope this helps. Dave.

[@alimajallow]

Hi sir how can l access your book

[@learnelectrics4402]

I don't have a book, but if you go to LearnElectrics.com you can use search to access all the videos and more. Thanks for watching.

[@wilfbrocklebank133]

I’m sitting am2 section d online exam, will these videos help me

[@learnelectrics4402]

Absolutely yes they will Wilf. All learning will help. I have put a link below to the 18th Edition help and tips videos playlist. These will show you how to read on-line questions and how to find the answers in the books. Everyone that has viewed them has had excellent results. There are 14 videos about 15 minutes each and they will really boost your knowledge and improve your chances of a pass. Good luck. Keep in touch.
