Testing Continuity of CPC, Polarity & Insulation Resistance of a 2 Way Lighting Circuit PVC Conduit
How to test dead for continuity of the CPC, insulation resistance and polarity of our 2 way lighting circuit in PVC conduit as we prepare for our City and Guild 5357 practical assessment 107 and AM2S.

Please Note: we have plastic light fitting and PVC conduit are which are fully insulated and we have metal light switch boxes and metal plates making them exposed conductive parts.
Videos are training aids for City and Guilds (C and G) and EAL courses Level 1, 2, 3 plus AM2, AM2S and AM2E.

Another great video Gaz, the passion and enthusiasm for the industry they you have is what these young people need to come into the trade well equipped with the knowledge and desire to do things right and protect our trade.
Wow what a lovely comment. Many thanks. Gaz 👍
I wish my lecturers are as interested as GSH ! They don’t turn up half the time !
Thanks Jake 👍
Fantastic clear video as always guys. I'd really appreciate it if you could put together some videos on filling out the various test sheets at some point thanks.
Great video Gaz as always. Good idea to put the Line in the earth/CPC bar, saves also having to null the resistance of the jump lead; just got to remember to put the Line back into the MCB once completed. Nice to see sequence of the tests for the 2 way lighting. If you have intermediate switching the process is the same except you have an extra switch to turn on/off. Almost forgot, nice to see the tests that prove that the CPC is connected to any exposed conductive parts.
Thanks for the detailed comment and you are correct for the intermediate switch(es). All the best. Gaz 👍
@@GSHElectrical You're welcome :)
Thank you for this channel.
I do the same put line to the CPC bar in the consumer unit gives a better connection. Another very good informative video for any Apprentices
Hi Paul, better connection in the earth bar and also our links are giving us issues at Tresham college with our readings. Thanks for the lovely comment. Gaz
@@GSHElectrical I have the problem with fluctuating readings when doing continuity tests and zeroing leads which I do connect length ways on croc clips , I have an old meggar 1552 it was second hand when I got it, i got brand new leads and its been calibrated I'm thinking of asking my company for a new tester. I can imagine the reply ...How much!
Paul Tipton depends on the type of tester and the wholesaler you buy from... shop around and good luck 👍
@@vievlogs589 The problem is my tester was given to me by my employer and wasnt new when I came to the company and as I don't supply the test equipment I'll have to have a word with the company electrical Qualifying supervisor to see if I can get one though the company accounts ( they can pay for it) otherwise I'll just carry on as I am it just takes longer.
Gaz, I forgot to say thank you as is got (95% in my Level 2 City and Guilds 2365 exam Tuesday 30th March 2021), a lot of help from your 18th Edition videos. I will continue watching and supporting your channel.
Fantastic as always Gary
Brilliant video Gaz, well and easily explained. 👍
Thanks Richard 👍
Superb lecture gaz as always.well done.
Stephen Allen thanks so much for the support. Gaz 👍
Gaz as the Earth lug is machine pressed ie attached to the metal box there’s really no point or need to probe on the box it self same for switch Yoke so Earth connection good, otherwise there would be no point in having the Earth lug. great video though 👍👍👍❤️
From someone who isn’t an electrician & is purely watching for entertainment value, what would be the procedure if the continuity between r1 & r2 was high ? What fault would this indicate & how would you fix it ?
Hi, to reduce resistance you can increase the conductor size and or shorten the conductor length these are the 2 most common ones. Thanks for the wonderful message and support. Gaz 👍
Hi Gaz, so a higher resistance isn’t ideal but there isn’t a “failure” as such ?. Thanks for the quick reply, thechannel is very well presented & I can see you live for your job/passion.
great video
Thanks 👍
Your videos are amazing sir, but I tired checking if the cpc is connector to the metal box of my two way switches and I’m not getting a reading for some reason. Have I done it correctly ? I connected one probe to common and one to the back box ? Please let me know thank you ?
👍
First
wow bro, so cool
You need to get the camera close to where you making contacts
It was a live (one take) if front of my learners video and not my normal controlled environment before my learners arrive (7am effort). Thanks for the feedback. Gaz 👍
You seem to have de-aged? 😁
For new electrical installation circuit minimum insulation resistance value is 20MOhms 😮 I’m sorry but this is very misleading. Where did you take this value from?
why the fuck did i pick electrics. im going to fail
