ABYC Marine Electrical Practice Exam

Strand loss during stripping could affect the ______ handling capability of the conductor.

1. voltage

2. amperage

3. current rating

4. insulation

The correct answer is: amperage

Strand loss during the stripping of conductors can significantly affect the amperage handling capability, which is fundamentally important for ensuring that the electrical system operates safely and efficiently. When strands of a conductor are lost during the stripping process, the overall cross-sectional area of the conductor is reduced. This reduction changes the conductor's ability to carry current without overheating. Amperage, which refers to the measure of electric current, is directly related to the number of conductive strands present in a cable. If strands are removed, the conductor's ability to safely carry the designed current is compromised, potentially leading to increased resistance and heat generation, which can cause further damage and pose fire hazards. Understanding the relationship between strand integrity and amperage handling capability is critical in marine electrical systems where safety and reliability are paramount. Thus, emphasizing proper stripping techniques to preserve strand integrity can ensure that the conductor maintains its intended amperage capacity.
