What is necessary to ensure safety when working with circuits that could create hazards during interruptions?

To ensure safety when working with circuits that could create hazards during interruptions, overload protection is essential. Overload protection devices, such as circuit breakers or fuses, are designed to prevent excessive current flow through the electrical circuit, which can lead to overheating, equipment damage, or even fire. When there’s a fault or overload in the system, these devices automatically disconnect the power supply, minimizing the risk of accidents or hazards related to high current.

In scenarios where interruptions occur, without overload protection, circuits may continue to carry dangerous levels of current, potentially resulting in severe safety risks. Properly designed and functioning overload protection is a critical component of any electrical system, ensuring that if a hazardous situation arises, the system can react accordingly to maintain safety for personnel and equipment.
