To avoid the overloading of domestic electric circuits, several important precautions should be taken:

• Do not connect too many electrical appliances to a single socket or circuit to prevent excessive current flow.
• Avoid using multiple high-power appliances simultaneously, especially on the same circuit.
• Distribute electrical appliances across different circuits to balance the load.
• Use fuses or Mini Circuit Breakers (MCBs) in the circuit to automatically cut off power in case of overload, preventing damage and fire hazards.
• Ensure proper earthing of electrical installations, which safely directs excess current to the ground.
• Regularly check and avoid using faulty or damaged electrical appliances and wiring.
• Avoid excessive use of extension cords or power strips for multiple devices on one outlet.
• Be mindful of the total electrical load in the home and do not exceed the safe limits of the wiring and circuits.

Following these precautions helps prevent circuit breaker trips, overheating, and electrical fires, thereby enhancing safety and electrical system longevity at home.
