Not sure what to release
Added 2025-02-13 18:13:38 +0000 UTCI'm not sure whether I should release the first video, this one with the flame test or both. Tricky.
And I still don't know the reason for the recall. Maybe a batch went out with the wrong plastic.

Flash to Internal Earth Bar - had "fun" of investigating identical situation while working for MK competitor. MK internal design is very similar to the one I've worked on. Main issue steams from BS standard requiring only 6mm distance between bars which in reality is not enough in specific conditions as we seen +12mm arcs initiated by switching operation. Unfortunately that fault can go unspotted during BS required tests due to some "vague" wording in test specifications and test setup

2025-02-28 09:32:47 +0000 UTCThere must be some reason for it. The plastic of this unit did seem to be self extinguishing, but with a carbon bridge the power could sustain arcing.

2025-02-16 01:10:27 +0000 UTCWatching the eFIXX video I've just had a thought: it's Grenfell, isn't it? MK have reviewed all their stuff very conservatively and decided to pull some. That's just a guess.

2025-02-14 13:33:06 +0000 UTCHi Clive, I found this information. It would indeed be about fire hazard due to arc flash in the switches. Nothing is said about how or where... https://www.youtube.com/watch?v=sRIc9YIfkn4

2025-02-14 11:29:22 +0000 UTCIf you're worried about YT punishing you for flamey fun, why not just put this video as unlisted (but public) on a second channel and then link to it from the description in the original less combustible first video?

2025-02-14 09:15:55 +0000 UTCMy two cents say release it, but maybe you could combine the two, and have the flame test as a "Bonus Extra Footage" at the end (if you're worried about repetition?) :)

2025-02-14 07:08:03 +0000 UTCThe only thing I can think of is where the plugs plug in. I wonder if that causes movement of one of the parts going to the switch making enough of a gap for an arc.

2025-02-14 03:18:44 +0000 UTCit's been recalled, release it as a matter of public safety awareness ;-)

2025-02-13 22:18:40 +0000 UTCI'm not sure this one adds enough to risk possibly upsetting Youtube censors. I'd probably just put a note in the description of the original saying that the plastic wouldn't stay alight when you tried to burn it.

2025-02-13 21:21:25 +0000 UTC“The product presents a high risk of fire as it has been identified that when the switch on the socket is being switched on, or switched off, or whilst it is under load, there is a possibility for an arc flash to occur. This could cause the socket and surrounding materials to ignite, causing a fire. The affected sockets do not meet the requirements of the Electrical Equipment (Safety) Regulations 2016 or the Plugs and Sockets (Safety) Regulations 1994.”

2025-02-13 20:17:09 +0000 UTCThe reason for the recall is explained in this video: https://youtu.be/sRIc9YIfkn4

2025-02-13 19:58:49 +0000 UTCOff hand I'd say both.

2025-02-13 19:48:18 +0000 UTCI'd recon it's the earth they recalled for.

2025-02-13 18:40:25 +0000 UTCI'm definitely not going to do that.
Big Clive
2025-02-13 18:39:02 +0000 UTCIt's odd because an arc flash usually needs phase and either neutral or earth in the immediate vicinity.
Big Clive
2025-02-13 18:38:43 +0000 UTCIn a way it feels like repetition.
Big Clive
2025-02-13 18:37:54 +0000 UTCWhat's the downside of releasing both?

2025-02-13 18:28:29 +0000 UTCJust read the gvnt announcement page that says "...there is a possibility for an arc flash to occur" So maybe load it up with unreasonable number of heaters and see if you can recreate an arc flash event when switching it and film that to go with what investigation you've already got. https://www.gov.uk/product-safety-alerts-reports-recalls/product-safety-report-mk-electric-mk-essentials-electrical-three-pin-sockets-with-switches-2411-0130

2025-02-13 18:28:27 +0000 UTCMaybe reach out and contact MK and ask them if they can give you the tech details for the recall??
Russell Couper
2025-02-13 18:24:28 +0000 UTCI've not taken many sockets apart but one thing could be the zinc coated steel earthing strap in addition to it only contacting with one side of the pin giving insufficiently low earthing resistance ?
Russell Couper
2025-02-13 18:23:33 +0000 UTCadd it on to the original, or release both. the fire test was interesting and i'm also curious to learn what is wrong with the thing that warants a recall!

2025-02-13 18:22:32 +0000 UTCmelty moments might upset the youtube monster😂 you and that lighter seem to make the monster tweak out.
james knight
2025-02-13 18:19:06 +0000 UTCBoth I'd say - it's not like you're saying anything critical to MK here and they were both interesting videos!
