ABYC Marine Electrical Practice Exam

Why is the use of an appropriate wire stripping tool necessary?

1. To increase wire strength

2. To prevent strand loss

3. To enhance appearance

4. To guarantee a secure connection

The correct answer is: To prevent strand loss

Using an appropriate wire stripping tool is essential to preventing strand loss. When wires are stripped improperly, there is a risk of damaging the individual strands of the wire, which can lead to a weaker connection or electrical failure. A proper stripping tool is designed to remove insulation without nicking or cutting the conductor strands, maintaining the integrity of the wire. This is particularly important in marine applications where reliable electrical connections are critical for safety and performance. A connection with damaged strands could lead to increased resistance, overheating, or even potential short circuits. Therefore, using the right tool is fundamental to ensuring that the stripped end of the wire can form a secure and effective connection with terminals or other conductors, which is crucial in maintaining the overall functionality of the marine electrical system.
