Mains cable blown out on two products

[telectrix]

Would it be an issue that the fuse it connected to the neutral and not the line? The fuse in this position was part of the testing of EN 60335-2-17 but it tested against short-circuit only and not perhaps someone/something like a metal bedframe cutting into the cable.

how do you know the fuse is in the N? if you look at the reverse side of the PCB, you can follow the tracks. might find it's fused in the L.

If you look on the left where the N wire goes in, on the other side it's soldered directly onto the left side of the fuse.

As the fuse hasn't blown it looks like the cable has been bent causing some (or all) of the strands to break leading to a hot spot/arcing whilst in use. The fact that it hasn't been noticed before it failed means it was possibly tucked under the mattress (if so very lucky there wasn't a fire) or behind a bed leg/castor as others have said.

Possibly been trapped under the bed leg /castor or behind the headboard against the wall.
I doubt it's a manufacturing fault.

It should be possible to trace exactly where the blown bits were, by laying them back onto the bed.

Possibly an adjustable bed?
