Strain Relief
Strain relief is a safety feature in electrical installations that protects cables and wires from being pulled, twisted, or damaged where they enter electrical devices or equipment. Think of it like a reinforced entrance point that prevents the internal wiring from being stressed or disconnected when the external cable is moved or pulled. It's similar to how a phone charging cable has a thicker section near the plug to prevent wire damage. Electricians use strain relief to ensure installations are safe and meet building codes. You might also hear it called "cable gland," "cord grip," or "stress relief" in job descriptions.
