Electrical overload occurs when an electrical circuit carries more current than it is designed to handle. This excess current can generate heat, potentially damaging wires and devices, and increasing the risk of fire. Common causes include using too many appliances on a single circuit or faulty wiring. To prevent electrical overload, it is essential to understand the capacity of your circuit and distribute electrical loads appropriately. Devices like circuit breakers and fuses are designed to protect against overloads by interrupting the flow of electricity when it exceeds safe levels. Regular maintenance and inspections can also help identify potential issues before they lead to overloads.
