What is a potential cause of overloading an electrical circuit?

Overloading an electrical circuit occurs when the current flowing through the circuit exceeds its safe carrying capacity. This often happens when loads are connected that draw excessive current, which can be due to the nature of the appliances or devices being used. When multiple high-draw appliances are connected to a single circuit, or when a single appliance requires more current than the circuit is designed to handle, it can lead to overheating and potentially create a fire hazard.

The design of the circuit, including the wire gauge and the ratings of circuit breakers or fuses, dictates the maximum allowable current. Therefore, ensuring that the loads connected do not exceed this maximum is crucial for safe operation. Understanding the current draw of devices ensures that circuits are used safely and effectively, preventing overload and the associated dangers.
