SAFETY SWITCH (RCD) INSPECTION AND TESTING A Residual Current Device (RCD), also known as a Safety Switch is a device located in the distribution boards of most workplaces but can however be of a portable type appliance. Just like your Portable Appliances, Occupational Health & Safety Act 2000 and Occupational Health & Safety Regulation 2001 requires you test your RCDs to ensure that they are working correctly. As part of their testing procedure, SPA test your RCDs and perform data capture to the Australasian Standard 3760. SPA provide testing on both portable and fixed “switchboard” type RCD’s. As RCD's should be tested for trip times and leakage current to determine their correct operation our technicians will perform both a "push button" and millisecond test to ensure that these devices are functioning within appropriate standards. The information from these tests shall be recorded and reported to you along with your appliance testing and tagging information. These devices are designed to save lives, if you have gone to the effort to have these live saving devices installed in your workplace it only makes sense to ensure they work! RCD Testing Procedures

• Locate switchboard and identify circuits protected by RCD’s
• Check switchboard door hinge, locking mechanism and weatherproof seal.
• Clean outside switchboard and general area.
• Barcode RCD Circuits for tracking and data management procedures
• Push button test to ensure RCD is operational.
• Plug in RCD test device and measure for trip time.
• Plug in RCD test device and measure for trip current.
• Check time and current fall within AS3760.
• Record all test results and action taken.
