Electrical tape, PVC Tape or insulating tape is used to insulate electrical wires and other materials that conduct electricity. It is a type of pressure sensitive tape. Vinyl is most popular material to make insulating tape as it stretches well and gives an effective and long-lasting insulation, buy other plastics Also can be used.
Color variations of Insulating PVC Tape
A wide range of colour variations is available, but all the different colours have an indication. Black tape is used for insulation and other colours indicates the voltage level and phase. When wires are phased, a ring of tape is placed on each end near the termination to indicate purpose of wire. Below is given colour and purpose table: –
Tape color |
Usage (U.S.) |
Usage (U.K.) |
Usage (International) |
| Black | Insulation Low voltage, phase A |
Insulation Low voltage, neutral |
Low voltage, phase B |
| Red | Low voltage, phase B | Low voltage, phase A | Sheath, 415 V 3 phase |
| Blue | Low voltage, phase C | Low voltage, phase C | Low voltage, neutral Sheath, 230 V |
| Brown | High voltage, phase A | Low voltage, phase A | |
| Orange | High voltage, phase B | Sheath, garden tools | |
| Yellow | High voltage, phase C | Low voltage, phase B | Sheath, 110 V site wiring |
| Green | Earth ground | Earth |
