What is the difference between a cable tray and a trough?
Several types of tray are used in different applications. A solid-bottom tray provides the maximum protection to cables, but requires cutting the tray or using fittings to enter or exit cables. A deep, solid enclosure for cables is called a cable channel or cable trough.
Which of the following covers the installation requirements for cable tray?
NFPA 70 – The National Electrical Code

How do you trench a cable?
Cable trenching is a method of laying cables into the ground by digging trenches. The cables are submerged underground via the trench and are then covered by a layer of earth, bitumen or concrete.

How deep should cable be buried?
Bury in the Ground: Dig 24 inches
- At 24-in.
- There’s one restriction: It needs a conduit where the cable is exposed on the outside of the house and to 18 inches below the ground.
- Burying the cable 24 inches requires more digging, so this method only makes sense if you have easy-to-dig soil or are renting a trench digger.
What is a trough in construction?
