PM of cables and cable trays

[Photocell]

Hi

We want to start the PM of cables and cable trays at our plant. We will check the following items in the course

1. Physical inspection of cables and cable trays.
2. Look for sharp edges along the bents of cable tray.
3. Check the ground connection integrity.

Can you please identify some more things that should be checked during this activity.

Thanks
