Cut to the required length using a sharp blade or tubing cutter. Ensure clean, square cuts for a professional finish.\u003c\/p\u003e\n\u003cp\u003eStep 2 — Placement\u003cbr\u003eSlide the yellow-green tubing over the grounding conductor and position it over the area requiring insulation or identification. For terminal connections, position the tubing to cover the exposed conductor up to the insulation boundary.\u003c\/p\u003e\n\u003cp\u003eStep 3 — Heat Application\u003cbr\u003eApply heat evenly using a heat gun set to approximately 300°C. Move the heat source gradually along the tubing from one end to the other, or start from the center and work outward. Maintain sufficient distance to avoid scorching or discoloring the yellow-green stripe pattern.\u003c\/p\u003e\n\u003cp\u003eStep 4 — Verification\u003cbr\u003eContinue heating until the tubing has fully conformed to the wire with a smooth, wrinkle-free surface. The yellow-green stripe pattern should remain clearly visible and uniform along the recovered length.\u003c\/p\u003e\n\u003cp\u003eStep 5 — Cooling\u003cbr\u003eAllow the tubing to cool naturally. Once cooled, the insulation is fully set and the ground wire identification is permanent.\u003c\/p\u003e\n\u003cp\u003eNote: Avoid overheating, as excessive temperature may cause the color pigments to shift or the tubing surface to become dull and uneven.
