Home wiring by experienced electricians
The licensed electricians at Bajic Electrical provide customized electrical wiring installations tailored to the needs of your building, whether residential or industrial. When selecting materials, we consider:
•The power requirements for each circuit
•Building size
•Type of occupancy
•Australian regulations
•Environmental factors
We use various wiring methods, with the two most common being:
•Loop at the Light Method: Previously popular in Australia before the 1990s, this method involves installing batten and rose light mountings to create blank terminals for loop connections. This approach is rarely used today.
•Loop at the Switch Method: More commonly used since the 1990s, this method routes power to the switch first rather than the light. It uses live, neutral, and earth wires to supply power to the light fitting. In residential installations, a 1mm to 1.5mm twin and earth cable is typically used, while commercial installations may require up to 2.5mm. The cable width is usually marked for easy identification.
In Australia, all electrical wiring must be performed by a qualified, licensed electrician. DIY or unlicensed electrical work can expose individuals to serious risks, including electric shock, electrocution, and house fires. Trust Bajic Electrical for safe and compliant wiring solutions.
Home Wiring
If your home is over 25 years old, it may be time to replace the wiring with modern technology and insulation to meet current Australian safety standards. This process involves a complete replacement of all existing wiring and components to ensure safety and compliance.
When rewiring an older home, we inspect for any faulty wiring and replace damaged or worn parts. All new wiring is installed according to the latest standards and color codes. For single-phase wiring, the color codes are:
•Active: Brown
•Neutral: Blue
•Earth: Green and Yellow
For three-phase wiring, the color codes are:
•Phase 1: Brown
•Phase 2: Black
•Phase 3: Grey
•Neutral: Blue
•Earth: Green and Yellow
This ensures your electrical system is safe, reliable, and up to date with current standards.
