The Essential tests - Continuity of the CPC

This is the first in a series of videos explaining the test procedure for the initial inspection and testing of an electrical installation.

Very good explanations and teaching

[@kyleclarkson-l3v]

great help with my revision a lot more concise than my college videos/tutors

[@JPElectric]

Thanks Kyle, good luck with your studies.

[@AngelaPeters-fy1tc]

Thanks so much and like the fact you checked your r1 +r2 readings from the table in OSG just to double check.

Thanks Angela appreciate your comment

Brilliantly explained, many thanks.

[@JPElectric]

Thanks cyberlightbeing. appreciate it.

Thanks Steve. Really appreciate your comments

Hello Sir. I'm on the coaster taking a course 2391. Yours videos has been tremendous help. I'd appreciated getting your answers based on my questions. It would be impossible to know exactly roughly the length of the cables in the reality world. How do I know what's acceptable reading and what's not? From what I understand is the lower the reading the better it is, so what if the reading comes in varies when testing on different circuit just say o.56 ohm ..1.2 ohm...1.5ohm ..2ohm..3 ohm? Thank you.

Hi sir, You have provided very useful information and the way of explaining is amazing. Thank you so much. I have a doubt on this topic. I read about this in a book and they mentioned as below. Can you explain about this👇👇 "The test should be made by connecting together the neutral and protective conductors at the mains position and checking between earth and neutral at every outlet by a continuity tester, which should show a reading near zero."

[@JPElectric]

HI Mounika, Thanks for the comment. The usual test is connecting the Line and Protective conductors together (Isolated of course) This is your R1+R2. R1 is the Line (Live) and R2 is the CPC. The reading will depend on the length of this loop. All cable has some resistance, But you would expect a very low Ohms reading. So if you have 20 meters of 2.5mm2 twin and earth cable The expected R1+R2 would be around 0.39 ohms.

Hi nice vid but a quick question, how did we know the length of circuit is 30m. Thanks

[@danielteyehuago1633]

Please which book and a page that we can find the information on cable size with it ohmic value per a meter.

[@danielteyehuago1633]

Please what instrument will be required for the testing here

[@danielteyehuago1633]

Please how can i get the on-site guide and. Which version is current
