Yet another LED floodlight that I ordered at the same time as the others, but this one took a while to arrive with it's SPECIAL surprise.
I checked the earth connection to the case and it was fine. That's a good start. I powered it up and the RCD (GFI) that covers my whole home tripped.
I reset the breaker and did an insulation test between live and ground and got an odd reading of just over 1 Megohm (not enough to trip the earth leakage detection alone).
On internal examination I found the output of the PIR sensor had its crimp connection sandwiched between the case and cover and the metal sealing rib had sliced through to the live metal. This explains why the insulation test didn't detect the real fault (PIR sensors relay not activated) and suggests the odd resistance reading was probably a convoluted path through the PIR power supply circuitry to the neutral, and then through the LED drivers primary circuitry to the switched live and earth.
I'm really glad the case was earthed, as otherwise the fitting would have worked as normal, but its case would have been live at 240V whenever the lamp switched on.
On a plus note, the case IS grounded and the power supply IS rated 10W.

EXCELLENT NOVEMBER 20TH 2022👉💎👈👉❤️👈❗
Hey Clive, how long did this one last you?
So, proof that the manufacturer doesn't actually bother to test the fully assembled product it sells. Scary.
Here's a historic Classic Clive. This is a pre-QuickTest video, instead WAGO connectors are used. Clearly this isn't mains tested at the factory and is probably only insulation tested. In which case, it would have produced similar results to yours, Clive.
Your very funny and educational,
Love you Clive ❤️
Always take Big Clive's advice and buy a Caveat Emptor marked product! 😜
I'm de constructing everything I buy now to check it's wired correctly! (Much to wife's amusement)
I know it's an old video Clive, but what brand is that red Phillip's head screwdriver? Is it a Stanley?
I can just imagine Clive when the house lost power saying oh that's not good. Just me?
The more usual term for an RCD in the US and Canada is 'GFCI' rather than 'GFI', the C standing for 'circuit.' I wouldn't normally nitpick, but it seems like something the viewers versed in electronics but not electrical might get confused about!
It's time to write to the Quality Control Department for that one!
What are those power clips you used as a temporary power supply called
the salient thing I've learned from watching your videos is that you can never trust cheap (probably MIC) electrical tat from the internet (and likely Poundland and its international equivalents). The workmanship is very variable, tending to shoddy. The real problem of course is our ("The West") never-ending demand for ever-cheaper crap from China and other "developing" nations, fueled by stagnant wages chasing lower and lower cost goods. Something's gotta give and it would appear to be a commitment to safely manufactured products, which is of course why Western capitalists love offloading manufacture to developing nations' sweatshops. But even slave laborers have their limits, most likely physical. While entertaining – when you're not electrocuting yourself and endangering your entire household of course – ultimately it's a serious indictment of the increasingly parlous state the non-rich live in. And we're ultimately doing it to ourselves.
Where did you get those "temporary" wire connector clamp???
Chinese don't care about anyone getting killed it's only about the money. Shame on them
