Flame test on a recalled MK socket

After releasing the video of my first look at this recalled socket, my Patreon supporters suggested doing a flame test on it. So here it is. Still no obvious issue though.

It's possible that the issue may affect some specific batches or that the arcing may only occur after some time and with a particular usage style.

Update - There are strong hints from pictures and info I've been sent that the issue is with the inclusion of the earth/ground busbar internally. Although the clearance looks good it appears that under some circumstances the arc of a load being broken may reach the bar and initiate a flashover.

Here's the official recall notice:-

If you enjoy my videos, you can help support the channel with a dollar or two for coffee, cookies and gadgets, and keep it independent from the quirks of the YouTube algorithm by supporting me on Patreon. Which also lets me link to my content on other platforms if YouTube uses the ban-hammer (again!)
I release content for critique and feedback on Patreon as soon as it has been made.
