Two Pins

The plug used with this socket only has two pins, which may have contributed to the failure.

The fault has occured between the line (active) and neutral conductors inside the socket, probably due to the plastic parts becoming worn. The 2 pin plug would have less support in the socket due to no earth pin, possibly causing bending or cracking of the plastic parts.
