Thermal hazard

Definition

A thermal hazard occurs when electrical components generate excessive heat, leading to potential damage or fire. It is a significant concern in household wiring and electrical safety.

5 Must Know Facts For Your Next Test

1. Thermal hazards can arise from overloaded circuits or faulty wiring.
2. High resistance connections contribute to thermal hazards as they generate more heat.
3. Proper insulation and circuit breakers help prevent thermal hazards.
4. Heat dissipation is crucial; inadequate ventilation around electrical devices can lead to overheating.
5. Regular maintenance and inspection of electrical systems are essential for identifying and mitigating thermal hazards.
