Why are Extension Cables Safety Tested?

  • To make sure you, your staff, and members of the public are safe, it is critical to test your extension cables. Cables are only one part of an electrical system, if there is a fault with any one part it can have an impact on all the other parts making the system unsafe or dangerous. We test every cable we manufacture for:
  • Insulation between each of the cores, making sure there is no electrical breakdown between the cores.
  • Polarity, making sure each pin in the plug is correctly wired to the corresponding pin in the socket, very easy to get wrong and cause an accident.
  • Cable Resistance, making sure all connections are good.
  • Visual Check, on the cable plugs etc.
  • Records, we keep a record of the results of the safety test, as part of our quality control and your assurance.  This testing is called a PAT Test or Portable Appliance Test. Should you want a copy of the PAT Test certificate do ask when ordering.
