QR code 1 -- Main protective bonding test

You videos are so clear and easy to follow. Good work sir!

What a well practiced teach in, your manner of speach is perfect for all to follow, well done! I think from looking at the comments here that how you have Tested the Gas Main Bonding left a lot of us scratching our heads, after all you were supposed to be measuring the Length of Cable Resistance and not picking up any resistance of the copper pipe connections, I was always taught to remove the Cable away from the Bonding point when Testing If I was fortunate enought to have the Main Water Bond nearby, then to use that as my return loop, take the reading at the Main Earth Marshalling Position and then look up the Tables showing the values of resistance for each cable to prove everything was correct.

very good explanation better than to go on course

[@cabbageswithcars9532]

this is how things should be taught easy to remember no overly complicated garbage

[@marccro8363]

Intrigued as to what that arrow on the gas meter is actually for now!

[@heiltd1286]

Christopher Kitcher's books are excellent too.

[@balogunmetzger1082]

Very easy to understand. Thank you.

[@lawrencebrown2369]

This is not correct. GN3 gives the value of 0.05 ohms for joints across bonds by earth clamps to the pipes. Nowhere does GN3 indicate that the resistance of the bonding conductor from end to end should be below 0.05 ohms.

Exellent😊

Just thought I would mention this here because it will be the first video you watch. The accompanying study material book, 'Practical Guide to Inspection, Testing and Certification of Electrical Installations: Conforms to 18th Edition' has more errors in it than GN3. I've only been using it for 4 or 5 days and already come across duplicate pages, spelling mistakes and instances of the wrong units being used in the calculations of worked examples. For an educational book this is not good enough and almost as unprofessional as the IET releasing the Guidance Notes without proof reading them.

[@scott1506]

where would you note this measurement on certificate / report? there is no section for r2 for bonding

[@londontrada]

You dont need to note the measurement, there is a tick box to confirm it in the bonding section of the certificate

[@MrKwelsh]

Shouldnt you disconnect from the pipework instead of the board to stop the chance of results from parralel paths?

[@stuartarnold9444]

If you did that you could not prove that the clamp had a good connection to the pipe, which is the whole point of the test.

[@zapszapper9105]

How much current do you need for a continuity test. .?

[@geoffball5803]

200ma

[@vithu001]

can i download this video to watch from my phone?

[@supremeasura3358]

yea

[@paulprice1963]

have you got to have 17th addition to do so 2392 inspection and test

[@mungabob]

thanks alot engineer

[@bloxwichman]

superb videos thankyou

[@juliusdelrosario7561]

tumbs up

[@TormDevil]

Good Video, shame about the copper sticking out of the Lug by the gas meter @ 4:17

[@ZEROWHO]

1000

[@ZEROWHO]

I want 1000
