Devices plugged into BS1363 Socket Oulet

[Midwest]

Came across this today, a device, which was plugged into a socket outlet, experience a short circuit of plug in power supply. Pics below.



I suspect the device was damaged by a heavy item being placed up against it over a period of time, causing the low voltage wiring being exposed & twisted, causing a short. So that can be rectified.

I'm questioning whether the device should have some additional fusing, like a BS1363 plug (in this incident it caused the 32A RCBO to trip), and in the last pic the authenticity of the CE mark. It does seem to be like the CE I've found on-line.

Its the fusing that perplexes me; no different to a phone charger etc I suppose. Did cause a large flash & bang.

If you look at the first pic, those two red wires connect straight onto the live & neutral terminals of the ‘plug’ pins (underneath the white plastic plate).

Its these two red wires(230V) that have got twisted and shorted out.

Wondered about that but those PCB tracks have been carrying some big currents, some have evaporated. It could be secondary to the wires shorting but I wouldn't expect the board to look like that if the problem started with shorted mains wires.
