The use and application of the Wiring Code SANS 10142-1 is well known to all of us, and covers fixed electrical installations of up to 1000 V AC and 1500 V DC and has been the topic of wide discussion over many years. This standard is called up by the Occupational Health and Safety Act as well as for prescribed electrical installations by the Mines Health and Safety Act. A new Part 2 of SANS 10142 has now been developed for voltages of up to 22 kV and power up to 3000 kW.
