Last of the "trebley-audio" videos.. The circuitry in this is breathtakingly simple, and is based on standard components. Standby power is effectively zero.
The video of the new recording device isn't up to the standard of the original Moto G4, so I'll probably be going back, which is a shame as the audio was louder and clearer.
Here's Mike's "test" of a breaker that went really well from a viewers perspective.

long time ago video Clive but still very informative. Question, you test it with Britisch plugs. which un ables switching polarity. But lots of EU countries use Schuko plugs.Which enables polarity switching. Also even CEE connectors are wired wrong. Would this GFI with these electronics work with a switched polarity? thus trip? or damage the thyristor?
I ask because i see GFI's used and advised for in-cable solutions on generators and powerstation solutions with a Schuko outlet to campers/boats and outlets etc.
Seems very simple and quite predictable, I certainly like both the construction and circuit design.
Thanks for showing us what it is.
Agree with Clive that the larger physical size of the 2-part module may be less likely to allow an internal phase/neutral short compared with the narrow-bodied enclosure type. The case of the grey module is marked 4kA fault rated whereas the higher 6kA seems to be common in the uk.
you are right those terminals are junk on par with spring tension type.
where can we get your RCD tester .We have other ones in canada and will those work at 120V .Good to test hot tub GFCI breakers
we remove all of those breakers from equipment that comes in from europe .We convieniently name them EuroTrash .First thing that happens is we pull them out and throw them in the trash and swap out with Mersen ucc fuse holders .We have only had some equipment come in with those style RCDs and we get them passed ast part of factory equipment . They are rated for the current and guaranteed to blow on short or overload !We get so much equipment full of those little breakers mounted on din rails .They are only approved for communications equipment not motors,drives and plcs on equipment !Thats for the CSA or UL/ULC standard .Not to many recycling facilities for those breakers .Loads of copper silver and paladium in some of the contacts
If it takes 20ms to trip at 50hz it’s not really tripping on the half cycle which only lasts 10ms
This way you can tell if it is a chinese high reliability ultra slow blow type.
What is the output voltage of the sense coil ?
neat one! 👍👍
Looking forward to the day that you get your hands on a Type B RCD to reverse engineer although there not cheap. Hopefully one turns up that has been taken out of service.
its to stop (err, try and stop) people like you from taking them apart to see whats inside XD XD
Dear Clive (also known in my circles as Mr Delicious Beard, not a joke me and my friend call this terrific chap Mister Delicious Beard 😊😋👌🤣) I have a question: the circuit breaker had a couple screws that would've opened it up in a jiffy. Could you open it up and show us the quench plates? I am super curious what those red blocks would've looked like on the inside 😀 Thank you very much for reading Clive! (or Mr. Delicious Beard 😋😄) a reply would be greatly and oh so very much appreciated! 😊 Thank you for the entertaining and informative content 👍
normal : current line L = N due to the voltage across R(12 k) is not appear,
else (because leak current to ground) the current in L line more than N make the AC voltage induce
the transformer the voltage is across R(12 k) and the SCR.on the trip coil make….all circuits OFF.
Your house GFCI trips at 100mA? Isn't that a potentially fatal amount of current?
Is the plastic a different type because it's transparent? If that be the case, I wonder if it has different flame retardant properties?
