Define the term "ampacity."

Ampacity refers to the maximum amount of electric current a conductor or device can carry before it reaches a specified temperature. This is crucial for ensuring safe and efficient electrical installations, as exceeding the ampacity can lead to overheating, insulation damage, and even potential fire hazards. Determining the appropriate ampacity is essential for selecting the right size and type of wire for specific applications, ensuring that the conductors can handle the load without risk of failure.

The concept of ampacity is determined by factors such as the conductor's material, cross-sectional area, ambient temperature, and installation conditions. It is a key parameter in electrical design, helping to ensure that circuits operate safely under peak loads while minimizing energy losses.
