Final answer:
Armoured sheathed cable and non-metallic sheathed cable must be supported or secured within a certain distance of every outlet box in electrical engineering.
Step-by-step explanation:
In electrical engineering, both armoured sheathed cable and non-metallic sheathed cable need to be supported or secured within a certain distance of every outlet box. This distance is typically referred to as the cable support or securing setback. The specific distance required can vary depending on the applicable electrical code and regulations.
For example, in the National Electrical Code (NEC) in the United States, armoured sheathed cables must be secured within 12 inches (approximately 300 mm) of the outlet box. Non-metallic sheathed cables must be secured within 8 inches (approximately 200 mm) of the outlet box.
These setback requirements are in place to ensure that the cables are properly supported and protected, minimizing the risk of damage and maintaining the integrity of the electrical system.
