At 4:22 in video it shows measuring voltage on pipe before removing meter. But if the fault current was small i would imagine you would read zero volts. Then it would shoot up to 230v once you break the joint. Im just guessing here. Please clarify if this may happen. That would mean you must always put clamp on pipe before removing a meter regardless of what voltmeter says.
At 4:22 the meter is removed, so I am not quite sure what you mean. If you measure with the meter connected, in a fault condition, you would measure a voltage. If the meter was removed, in a fault condition, you could read a fault on either side of the meter, but because the current has nowhere to go, it will just sit there until something or someone, completes the circuit. And that is the issue
If the plastic pipe comes out of ground and changes to copper in house, then does it need to be bonded. ?? I mean it could become live if an electrical fault occurs..
No, it does not need to be bonded as it does not go into the ground (zero potential). In this instance, the circuit protective conductor of the appliance will be sufficient
I watched another video where a chap suggested a faulty solenoid on a pipe could make the pipe live. Bit scary if the pipe could be sitting there at 230V . Of course with RCD protection one should not get killed if they touch it, but if it was bonded it might be safer ? What are your thoughts on this type of scenario.
Brilliant video, really helpful and a clear delivery of how and why Bonding and CPC's are used. Well done Adrian.
Clear and concise! Great use of references! Thanks for sharing!
Very good video dude. Clear, concise and easy to understand. Also I think your disclaimer at the beginning hits the nail on the head.
Thank you 🤗
I get mixed reviews of the disclaimer, but I think the training industry lets people down and someone needs to say something
Great video... Keep up good work
Thank you for taking the time to give me feedback 🤝
@@Pure_electrical_training it's well deserved mate..
Thanks for your great videos.
Well explained.
Glad you like them!
Brilliant explanation
Thank you 🙏
Great video 😊
Thank you Matthew 🙏
Lovely vid 👍🏼

Not a spark, but surely if there was a current flowing, however small, then there must be a voltage present to make that current flow.
Incorrect. The neutral has the same current as the live wire at 230 volts. The neutral is zero volts :)
