CATU Arc Flash Protective Clothing Kits

This week UK DNO contractors have been protected against arc flash hazards by purchasing Catu Arc Flash Protection Kits for workers removing 100A cut out fuses on private networks for sub-metering purposes. 

The following are used to determine proper equipment for protecting against an electric arc:

  • Maximum fault current value
  • Phase / ground rated voltage at the site of the risk
  • Distance between the source of the arc and the reception surface
  • AC cycle number and the mono or three-phase circuit type
  • Location where the arc is produced (cofined space)

After recording these parameters, the correct protective clothing and PPE can be determined - 8 to 100 cal/cm² or class 1 or 2.
