Large-Scale Incoming Mains Installation – Ester Electrical

High-Capacity. Mission Critical. Built for Scale.

Ester Electrical is proud to be delivering one of our largest incoming mains installations to date—a major electrical infrastructure milestone on a large-scale development project.

The installation features 20 x 630mm² single-core aluminium cables, supplying power to the main distribution board. It’s a high-current, high-precision job that reflects our ability to scale with the most demanding project requirements.

Our role includes:

• Supply and installation of 20 x 630mm² 1C aluminium mains cables
  
• Termination and connection to the main distribution board
  
• Coordination with structural, civil, and other service teams
  
• Detailed QA and safety methodology
  
• Commissioning for future load capacity
  

Powering tomorrow’s large-scale builds

Heavy-duty mains work requires more than cabling—it demands planning, load forecasting, technical design, and absolute precision in execution. We're proud to be trusted with such a critical component of this development.

This project reinforces our expertise in high-capacity supply systems and our ability to support Auckland’s growing demand for robust, scalable infrastructure.
