Why must aluminum wire be stripped carefully?

• A. It is more conductive than copper
• B. It is more flexible than other wires
• C. Individual strands can easily break after being nicked
• D. It creates a higher risk for short-circuits

Answer: (C)

Aluminum wire must be stripped carefully primarily because individual strands can easily break after being nicked. Aluminum is a softer metal compared to copper, making it more susceptible to damage when improperly handled. If the insulation is stripped too aggressively or carelessly, there is a risk of nicking the strands. Even a small nick can compromise the integrity of the wire, leading to potential failure in the connection. This characteristic is particularly important in electrical installations, where maintaining a solid electrical connection is crucial for safety and performance. This careful handling helps prevent issues like connectivity problems or overheating due to increased resistance at damaged points in the wire.
