Great video Mr JW
Hi JW. Thanks for the great videos. Can you advise why Zs on ring circuit supplying socket outlets with 32A type B Mcb, measured at 3 ohms is acceptable if additional protection is provided by 30ma rcd? I thought the max Zs for the circuit should be 1.10 ohms. Thanks
Polarity in ac circuits is to guarantee that when the overcurrent protection devices operate, the circuit is in fact dead due to the fact that all protective devices are/should be connected to the live conductor. If polarity is reversed then even when a protective device operates, it will still be live.
Thanks
great video john ward. came across these videos today. currently on a course, they are helping alot with home revision.
I could follow this guy all day! so simple and in depth explanation. Why do i bother search other videos through a title? i always land back here to John Wards videos. Been subbed for a while now and will continue.
A very nice presentation, hope you continue to educate students through the internet.thanks
I have never seen this type of information explained so clearly. Thank You.
What tests would you do before changing a consumer unit?
Thank you for making these videos its helping me a great deal to get qualified.
Hello JW
Is it enough tester like kewtech kt63 dor all of this measurments to test? Or i need aditional tester on top of that?
Thanks
You are a god send my friend. I'm doing my level 3 after a few years hiatus from the field and was really struggling before I watched your videos. For some reason I really understand topics better when you explain them compared to my lecturer who just wizz's through everything at lightning speed and gets annoyed when I ask a question.
Hello John, great videos, so do the circuits for both continuity and insulation resistance tests have to be dead? Cheers. p.s i am learning level 1 in electrical installations currently.
Legendary.. keep the vids coming
i have learn a lot from you thanks https://youtu.be/UpcipI4VQIA
Can you make some of the basic electrical videos for download? I'd love to have them when I'm out if signal. I'm loving them for revision.
What will be the recommendation for plastic consumer with regards to amendment 3 metallic consumer units when doing a periodic inspection.

thanks JW
i actually find you quite sexy 🙂 x
Hi JW, do you provide assessment study for electrical earth leakage tripping ? And can you provide me your email address ? Thanks
Hey John, I'm about to start a new job on electrical team fitting out barges would all this stuff be relevant.
Regards
John
EXCELLENT PRESENTATION
Hi John, Great videos, wondering if you could do a video about star and delta connections and equations, thanks and keep up the good work.
