What are the three major selection factors when replacing wire?

The three major selection factors when replacing wire are size, insulation, and environment.

Understanding these factors is crucial for ensuring the safety and efficiency of electrical systems.

Size refers to the gauge of the wire, which determines its current-carrying capacity. Using the correct size is vital to prevent overheating and potential fire hazards.

Insulation is significant because it protects against electrical shock and short circuits. Different applications may require specific insulation types to withstand various conditions, such as heat, moisture, or chemical exposure.

The environment factor considers where the wire will be used, whether indoors, outdoors, or in harsh conditions. This influences not only the type of insulation required but also the overall durability and suitability of the wire for its intended application.

These three factors ensure that the wire functions correctly, complies with safety standards, and meets the needs of the specific electrical application.
