What must be removed to prevent electric shock or fire?

To prevent electric shock or fire, addressing a dangerous overload is vital. An overload occurs when the current flowing through a circuit exceeds its designed capacity, which can generate excessive heat and pose a fire risk. Electrical circuits and devices are designed to handle a specific amount of current; exceeding this limit can lead to insulating materials breaking down, sparking, or even causing the circuit components to fail.

Overloads can happen due to multiple devices drawing power beyond what the circuit can handle or due to malfunctioning equipment. Installing protective devices like circuit breakers or fuses helps manage overloads by interrupting the flow of current when it becomes too high, thus minimizing the risk of fire or electric shock.

While vibration, voltage spikes, and loose connections can also pose safety risks and contribute to electrical failures, the most direct concern regarding the immediate prevention of shock and fire is the management of dangerous overload situations. Addressing these conditions effectively safeguards both equipment and users from harmful consequences.
