What does "source of energy" refer to in electrical safety?

The term "source of energy" in electrical safety refers to any power supply that has the potential to energize circuits. This encompasses a broad range of power sources, including but not limited to utility power supplies, batteries, generators, and photovoltaic systems. Understanding this concept is vital for ensuring electrical safety because recognizing all possible energy sources helps workers identify potential hazards and necessary precautions when working with or around electrically powered equipment.

By acknowledging that a source of energy can be anything that supplies electrical power, workers can better assess risks and implement appropriate safety measures to prevent electrical shocks or accidents. Thus, identifying any power supply capable of energizing electrical circuits is fundamental to adhering to safety protocols in the workplace, ensuring a safer environment for everyone involved.
