Branch circuits larger than ______ amps shall supply only non-lighting loads.

Branch circuits larger than 50 amps are required to supply only non-lighting loads based on the electrical code. This regulation helps ensure safety and efficiency in electrical installations. Circuits that handle larger amperage are often designed to manage heavy loads that generate significant heat and may cause issues if lighting is also connected. The limitation to non-lighting loads prevents potential hazards, including overloading circuits and increasing the risk of electrical fires. Properly following this guideline is crucial for ensuring residential and commercial electrical systems operate effectively and safely.
