Scotch® Super 33+ Vinyl Electrical Tape is a 7 mil thick, premium grade tape that provides electrical insulation for all wires and cables rated up to 600V. The flame retardant tape withstands a temperature range of 0 to 221 °F ( 18 to 105 °C).
Electrical tape is a pressure-sensitive tape used to insulate materials that conduct electricity, specifically electrical wires. It stops the electrical current from accidentally passing to other wires, which could create a short or even start an electrical fire.
Black is generally used as an insulating electrical wire. Other colours are known as 'phasing tapes'. These colours indicate the voltage level and phase of the wire. Phasing tapes are used on wires that only come with black insulation.
