What is a common effect of overloaded circuits?

Overloaded circuits occur when the electrical load exceeds the capacity of the wiring or circuit components. This excessive load generates heat, which can lead to a variety of dangerous situations. One of the most serious consequences of overloaded circuits is the increased risk of electrical fires. When wires overheat due to excessive current flow, they can damage the insulation surrounding them or even ignite nearby combustibles, causing potentially devastating fires.

It's important to recognize that maintaining proper load levels is crucial for safety. Addressing circuit overloads by redistributing loads, upgrading wiring, or installing additional circuits can help prevent these hazards. Understanding this aspect is vital to ensure both safety and compliance with electrical codes.
