Professional Installation Requirements
- Installation, testing and commissioning must be carried out by a licensed electrician in accordance with applicable Australian wiring rules, manufacturer instructions and local electrical safety requirements. Verify the required Australian approval and RCM marking before installation.
Applications
- Residential distribution boards
- Commercial switchboards
- Three-phase final circuits
- Lighting and general power distribution
- HVAC and small motor circuits where a C-curve characteristic is appropriate
- Overload and short-circuit protection in low-voltage AC installations
Standards & Compliance
