About This Project
Installation of new 630A electrical supplies to support ongoing expansion
What We Did
Overview
This project involved the installation of two new 630A electrical supplies to support external chiller units at a commercial site. Following a detailed site visit, a tailored solution was developed to deliver robust, high-capacity power distribution while accommodating both internal and external installation constraints. The works were designed to ensure compliance, reliability, and minimal disruption to the client’s operations.
Objectives
- Provide two independent 630A power supplies for new external chiller units
- Install high-capacity cabling suitable for long-term operational reliability
- Ensure safe, compliant routing of services both internally and externally
- Integrate new supplies with existing infrastructure efficiently
- Deliver a fully tested and commissioned installation
Work Completed
- Supplied all materials, plant, and equipment required to complete the installation
- Installed 2 runs of 120mm 4-core SWA cables with separate CPC conductors per supply, routed to designated external locations near the wooden fencing
- Carried out internal containment modifications to accommodate the new cable routes
- Installed external containment systems along the steel frame and rear wall using a flexible foot mounting system, ensuring durability and alignment with site conditions
- Mounted 2no 630A switches within IP-rated GRP enclosures at external connection points for safe and weather-resistant operation
- Completed all necessary core drilling, penetrations, and fire stopping, maintaining the building’s fire integrity
- Performed all cable terminations, ensuring secure and compliant connections
- Conducted full testing and commissioning of the installation to verify performance and safety
Outcomes
- Successful delivery of two fully operational 630A power supplies for chiller units
- Seamless integration with existing electrical infrastructure
- Installation completed to a high standard of safety, durability, and compliance
- External systems protected against environmental conditions through IP-rated enclosures and robust containment
- Future-proofed capacity for ongoing operational demands
Customer Benefit
- Improved operational reliability with dedicated, high-capacity power supplies
- Minimised risk through compliant installation, fire stopping, and certified testing
- Enhanced system longevity
- Reduced downtime and disruption through efficient planning and execution
