Shortcoming in Maintenace ; Motor Control Panel (MCP)

a) Externnaly, most MCPs are messy with peeled paint, oil and dirt.
b) Internally, the control wirings and power cables are not strapped and rounted properly.
c) MCPs are ussualy set upon by water, oil and fibre. Little is done to improve the situation.
d) Screws are usually not complete or totally absent from front and back covers. As such many covers are seen..
e) Contactors are not opened up for servicing. They are left to operate until failures sat in.
f) Power fuses are sometimes replaced not according to connected load but what are available in stock. This can lead to single phasing.
g) Defective indicating lights and starts/stop push buttons are commonly found. Replacement are normally by cannibalising from spare starter boards.
