Mandatory Inspection and Testing (Verification) is required by AS 3000 across Australia & NZ before an electrical installation can be placed into service. This video course of 90 mins covers all the necessary Theory and practice of Mandatory Testing.
Adhering to AS 3000 and AS 3017 standards, this video covers essential electrical testing procedures and the inspector's role in investigating electrical shock incidents.
It highlights the importance of verifying installations before energising, conducting thorough visual inspections, and assessing consumer mains for safety.
Key topics include switchboard compliance, protective devices, wiring systems, and the need for proper earthing arrangements to safeguard against environmental factors and mechanical damage.
AS 3000 outlines essential testing standards for electrical installations, highlighting mandatory tests such as continuity of earthing systems, insulation resistance, and polarity testing.
These tests ensure safety by verifying correct connections and the integrity of protective devices.
Proper procedures must be followed, starting with continuity tests and concluding with RCD tests, while using appropriate testing equipment.
Compliance with AS 3000 and local regulations is crucial to prevent hazards and ensure safe electrical practices.
Essential guidelines for electrical safety inspection and testing are outlined, focusing on continuity and insulation resistance testing.
Key procedures include isolating the supply, ensuring resistance levels meet specified standards, and assessing all metal frames and appliances.
Special attention is given to poly pipe installations and RCD considerations, emphasising the importance of site safety and functional testing equipment.
Final tests confirm the integrity of connections and compliance with safety standards.
Multi-occupancy testing efficiently manages electrical connections across multiple units using a resistor block with various ohm ratings.
The method involves connecting the resistor block to the neutral for resistance measurement, enhancing efficiency by minimising lengthy test leads.
Continuity testing is performed at the group meter box without wire removal, ensuring correct connections, while insulation resistance tests target safety compliance.
The streamlined process is particularly effective for three-phase installations, focusing on riser cabinets and proper cable management.
