Here’s a plugtop that was wrapped in insulating tape. That’s always a worry as one can imagine problems that may be hidden within.
Once the tape was removed there were cracks all over the underside of the plugtop.
As soon as I started to undo the screw the whole thing fell apart in my hand. The only thing that stayed together were the terminals, and that was because they were attached to the cord.
A new plugtop costs very little and should have been changed as soon as it was damaged.
