In addition to insulation, 3mm electrical tape can also be used for color-coding wires and cables. By using different colored tapes, it becomes easier to identify and trace specific wires within a complex system. This can be especially helpful when troubleshooting or making repairs, as it eliminates the need to follow each wire individually. The thin width of 3mm tape allows for multiple colors to be used in a small space without causing confusion or bulkiness.
3mm electrical tape

Electrical tape has a niche in electrical work. Its stretchy properties and specific installation recommendations limit its versatility. Duct tape, however, is extremely versatile when temperature is not an underlying obstacle. It works great on metal, wood, glass, or plastic surfaces for applications including:
One of the main uses of 3mm electrical tape is insulating electrical wires and connections. When working with electronics or electrical systems, it is important to ensure that all exposed wires are properly insulated to prevent electrical shocks or short circuits. The thin width of 3mm tape allows for precise wrapping around wires and terminals, creating a secure barrier against electrical currents.
