When running connectors in bends, which type of cable requires special attention?

When running connectors in bends, nonmetallic-sheathed cable requires special attention due to its construction and flexibility. Nonmetallic-sheathed cable, often referred to as NM cable or Romex, consists of insulated conductors sheathed together in a plastic outer jacket. When bending this type of cable, it is important to ensure that the bend radius meets the manufacturer's specifications to prevent damage to the conductors inside the cable. Overly tight bends can lead to insulation damage, shorts, or compromised performance.

In contrast, armored cable has an outer layer of metal armor that provides added protection and strength, making it more resilient to being bent. Flexible conduit is designed specifically to flex and move without damage. Underground cable typically has a robust construction to withstand environmental stresses, but its installation and routing may have different considerations. Nonmetallic-sheathed cable's vulnerability to tight bends and the need for adhering to bend radius guidelines make it the focus of special attention during installation.
