What is a common risk associated with improper wire sizing?

• A. Reduced energy efficiency
• B. Overheating and fire hazards
• C. Increased electrical noise
• D. Shortened circuit life

Answer: (B)

Improper wire sizing can lead to overheating and create fire hazards. This is mainly due to insufficient wire gauge for the amount of current flowing through it; a wire that is too small for a given load can heat up excessively because it doesn’t have the capacity to handle that electrical load safely. As the temperature rises, the insulation around the wire can deteriorate, which may eventually lead to a short circuit or an electrical fire. Additionally, appropriate sizing ensures that the wire can carry the expected load without excessive resistance. When wires are sized correctly, they remain within safe temperature limits and reduce the risk of fire hazards. Understanding wire sizing and its implications is crucial for electrical safety and compliance with electrical codes.
