A 1/2″ strain relief nut is a type of strain relief that is used to protect electrical wires and cables from damage. It is typically made of metal or plastic and has a threaded hole that the wire or cable is inserted into. The nut is then tightened to secure the wire or cable in place. The 1/2″ designation refers to the diameter of the threaded hole.
Strain relief nuts are used in a variety of applications, including:
- Electrical panels
- Motor mounts
- Lighting fixtures
- Solar panel systems
- Fire alarm systems
They help to prevent damage to electrical wires and cables from vibration, movement, and tension. This can help to extend the life of the wires and cables and prevent electrical hazards.
