What is a disadvantage of cable tray?
A- it's is free-air rated
B- installation and maintenance is costly
C- it is not accessible easily
D- it does not work for high wattage
Why is the answer C ( it's not accessible easily) since this is a open tray system and you can access it and add or remove lines easily, the whole point is to be flexible and accessible. This is what I've used at my work - lab project, the owner loved the system.
