What could happen if a conductor exceeds its ampacity?

When a conductor exceeds its ampacity, it means that the current flowing through the conductor exceeds the maximum amount it can safely carry. Ampacity is determined based on several factors, including the conductor's material, cross-sectional area, insulation type, and the surrounding environment.

When a conductor carries more current than its ampacity allows, excessive heat is generated due to resistance within the conductor. This overheating can lead to various dangers, primarily fire hazards. The insulation surrounding the conductor may deteriorate or melt, further exposing the conductor and increasing the risk of electrical faults. If this condition persists, it can cause significant damage, not just to the conductor itself, but also to surrounding materials and potentially ignite flammable substances nearby.

It's important to adhere to the ampacity ratings to ensure safety in electrical installations, preventing overheating and the associated risks.
