When is it recommended to use a wire stripper?

1. For cutting wood

2. To remove insulation from wire

3. To cut metal sheets

4. To splice power lines

The correct answer is: To remove insulation from wire

Using a wire stripper is specifically recommended for removing insulation from wire. This tool is designed to efficiently and safely strip the outer insulation without damaging the wire itself. Insulation needs to be removed in order to make proper electrical connections, whether you are connecting wires to terminals, creating splices, or preparing wire for a device. The other options do not pertain to the intended use of a wire stripper. Cutting wood or metal sheets requires tools designed for specific cutting tasks, such as saws or shears, and are not suited for wire stripping. Splicing power lines also typically requires specialized tools that are designed to handle higher voltage and ensure safety, rather than a wire stripper. Thus, the appropriate context and function of a wire stripper make the use of the tool for removing insulation from wire the correct scenario.
