When using heat-shrink tubing, what is the consequence of not applying heat properly?

When heat-shrink tubing is used, proper application of heat is crucial for ensuring a secure and effective seal around the conductor. When heat is not applied correctly, the tubing may not shrink sufficiently to fit tightly around the conductor. This inadequate adhesion can lead to poor insulation, increased exposure to environmental factors, and potential failure of the electrical connection over time.

The result is that the tubing will not form a reliable protective barrier, which is essential for maintaining the integrity of the electrical connection and preventing issues such as moisture ingress, abrasion, or other forms of damage. Therefore, the importance of applying heat properly is to ensure that the tubing adheres correctly and performs its intended function effectively.

Other options may reference issues of safety or installation quality, but they do not directly address the specific functional failure caused by improper heat application when using heat-shrink tubing.
