Consumer Unit Bus-bar M.C.B. reliable clamping.

AJJewsbury: 
 

The poster of the video was referring to M.C.B. design where it is possible to get the bus-bar finger the wrong side of its cage clamp, where it just makes fortuitous contact, and is not gripped securely.

But obviously not the cause in this case … as the one that burned didn't have a finger-type bus-bar.

Yes Andy, we all know that.
