Red Seal Powerline Technician Practice Exam

Which type of tool should be used for cutting power cable?

1. Hand saws

2. Auger bits

3. Cable cutters designed specifically for electrical cables

4. Wire strippers

The correct answer is: Cable cutters designed specifically for electrical cables

Using cable cutters designed specifically for electrical cables is essential when cutting power cable. These tools are engineered to handle the specific materials and constructions of electrical cables, ensuring a clean cut without damaging the inner conductors or insulation. This is important because improper cutting can lead to fraying, increased resistance, or even short circuits when the cable is later used or terminated. Cable cutters typically feature sharp, serrated blades that can easily slice through the outer sheath and insulation, allowing for a precise cut while minimizing the risk of injury or cable damage. They are also designed to provide adequate leverage and ergonomic support, making the task safer and more efficient for the operator. On the other hand, tools like hand saws are not designed for the precision required in electrical work and can cause uneven cuts, posing safety hazards. Auger bits and wire strippers serve entirely different purposes; auger bits are for drilling and wire strippers are meant to remove insulation from wires rather than to cut cables. Therefore, using purpose-built cable cutters is the most appropriate and safe choice for cutting power cable.
