Covers of outlet boxes having holes for flexible cord pendants must have what provided to ensure safety?

When dealing with outlet boxes that have holes for flexible cord pendants, it is essential to ensure safety by using approved bushings. These bushings serve several critical functions. First, they protect the flexible cord from sharp edges of the outlet box and prevent wear that can lead to electrical shorts or damage. Additionally, approved bushings help to secure the cord and ensure that it is properly supported, mitigating any risks associated with the cord being able to move or pull out of the box.

Using approved bushings also complies with electrical code requirements, which emphasize the necessity of protecting wiring systems to maintain safety standards. This ensures overall protection for both the electrical installation and the individuals using the equipment connected to that circuit.
