A light fixture that weighs more than what weight must be supported independently of the junction box?

In Michigan, the regulation states that a light fixture weighing more than 50 pounds must be supported independently of the junction box. This is crucial because junction boxes are designed to support only a certain amount of weight, and exceeding this limit can compromise the safety of the installation. Proper support for heavier fixtures is necessary to prevent potential hazards, such as a fixture falling, which could cause damage or injury. Supporting fixtures over 50 pounds independently ensures that they are securely anchored, adhering to both safety and building code standards. Understanding this requirement is vital for anyone involved in electrical installations and maintenance.
