Benefits: Participation
1. No more socket breakage and so it improves the availability of charging point. For implementing this project there was participation from both maintenance and operation in CLP
2. Electrical shock hazard is eliminated in the socket as there is no more damage. and also from the mobile vehicle maintenance section.

Single Point Lesson: Remark / Management Comments:
Sometimes the solution can be very simple for a complex problem. It takes someone’s imagination
to think through the problem to arrive at it.
