Three-Phase Equipment Testing & Tagging
Three-phase electrical equipment is the backbone of Australian industry, powering everything from heavy machinery and welders to commercial ovens and large HVAC systems. Due to the higher voltages and power levels involved, three-phase equipment presents unique safety risks that require specialist testing knowledge and equipment.
Aussie Test & Tag provides expert three-phase testing and tagging services carried out by technicians who understand the complexities of industrial electrical systems. We test all types of three-phase equipment including fixed and portable machinery, extension leads, power distribution boards and temporary power setups on construction sites.
What Our Three-Phase Testing Includes
Our comprehensive three-phase testing service covers:
- Visual inspection of plugs, sockets, leads and connectors for damage or wear
- Earth continuity testing across all three phases and the earth conductor
- Insulation resistance testing between all conductors at the appropriate test voltage
- Earth fault loop impedance testing to verify adequate fault current path
- Phase rotation verification to ensure correct motor direction
- Current load testing under operating conditions where safe to do so
- Durable colour-coded tags and detailed digital test records
Why Three-Phase Testing Is Critical
Three-phase equipment operates at higher voltages (typically 415V in Australia) and carries significantly more current than standard single-phase appliances. A fault in three-phase equipment can result in catastrophic failure, serious injury or death. Regular testing identifies deteriorating insulation, loose connections and earth faults before they become dangerous. Australian WHS regulations require all electrical equipment used in the workplace to be regularly inspected and tested, regardless of voltage.
Why Choose Aussie Test & Tag?
Our technicians are experienced with industrial and commercial three-phase environments. We carry specialised testers capable of handling 415V equipment and various plug configurations including 20A, 32A and 63A industrial connectors. We schedule testing around your production requirements to minimise downtime and keep your operations running safely.
