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.

I wish my lecturers are as interested as GSH ! They don’t turn up half the time !

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.

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.

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 ?

[richardwash]

Brilliant video Gaz, well and easily explained. 👍

[train]

Superb lecture gaz as always.well done.

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 👍👍👍❤️

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 ?

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

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?

You need to get the camera close to where you making contacts

why the fuck did i pick electrics. im going to fail
