Aim:

To learn the correct way of stripping, twisting, and insulating wires.

Requirements:

• Insulated copper wires (2–3 pieces, 20–30 cm long)

• Wire stripper or cutter

• Electrical insulation tape

• Safety gloves

Working:

Step 1: Safety First

• Wear gloves to protect your hands.

• Ensure no live current is connected while working.

Step 2: Strip the Wire

• Use a wire stripper to carefully remove 1–2 cm of insulation from both wire ends.

• Avoid cutting into the copper strands.

Step 3: Twist the Wires

• Place the two exposed copper ends together.

• Twist them clockwise until the joint is tight and no strands are sticking out.

Step 4: Insulate the Joint

• Wrap electrical tape around the exposed copper.

• Ensure no copper is visible.

Step 5: Test the Joint

• Gently pull the wires from both ends.

• If the joint is firm, it is correct. If it loosens, repeat the process.
