Course Description

Duration 8 hours

This course was originally developed in response to industry concerns expressed by the regulator as to the standard of testing being undertaken by licensed electricians. It is designed to refresh the testing skills and provide a clear understanding and methodology for testing of the 6 mandatory tests required under AS/NZS 3000: 2007 which now includes Residual Current Devices and Fault Loop Impedance . The course also covers Voltage Drop, Faults on the MEN and Fault Current. 

It involves both a theory and practical component. Participants are required to provide their own testing equipment with which they are familiar. Testing equipment is checked on the day before the practical component to establish any variations from the accepted norm.

The course includes the following

• Understanding the standards and regulations. 
• Testing options, and why to test.
• Mandatory tests.
• Why test earth continuity
• Why test insulation resistance and polarity.
• Why test for correct circuit connections, Earth Fault Loop Impedance and RCD’s.
• Earth continuity choices, testing main earth using trailing lead.
• Testing protective earths and bonds using trailing lead.
• Earth conductor values and equipotential bonding of water and pipes
• Fault loop examples and testing insulation resistance.
• Testing mains polarity using fixed resistors
• Testing metered mains polarity using fixed resistors.
• Testing main switch/ circuit breaker operation/interconnections
• Testing socket outlet polarity/earthing/switching/legend/interconnections.
• Testing earthed or bonded items from a socket outlet and testing circuit neutral interconnections.
• Finalise dead testing and live testing. 
• Using fixed resistors
• Checking  voltage drop, Fault current ratings, RCD’s

Course participants are required to undertake both a practical and theory assessment. The pass mark for this assessment is 80%
