Three Phase Power Installation in Preston
Walker Electrical Developments installs three phase power systems for industrial and commercial clients across Preston and the PR2 area. Three phase power is standard across most manufacturing, production, and large commercial environments, providing the capacity and balance needed to run heavy machinery, motors, large drives, and high-demand electrical equipment. Our NICEIC registered engineers design and install three phase systems that are correctly sized, properly protected, and fully compliant.
More Information
Correctly Sized Three Phase Systems for Your Load
Getting the sizing right on a three phase power installation matters. An undersized system creates problems as your business grows. One that is oversized wastes money at the design and installation stage. Our engineers carry out a thorough load assessment before any design work begins. We calculate current demand, account for future growth where possible, and design a three phase system that works efficiently and reliably from day one. All work is designed to current IET Wiring Regulations.
New Supplies and Upgrades to Existing Installations
Some projects require a new three phase supply to be brought into a premises for the first time. Others involve upgrading an existing supply to a higher capacity or reconfiguring the distribution arrangement. We handle both. For new supplies, we manage the process with the Distribution Network Operator to bring a new service into your site. For upgrades, we assess the existing installation and plan the works to minimise any disruption to your operation.
Full Testing and Commissioning on Completion
Every three phase power installation we carry out in Preston is fully tested and commissioned before handover. We verify phase rotation, voltage balance, protection settings, and earth fault loop impedance across all circuits. You receive a full Electrical Installation Certificate with all test results, giving you the documentation you need for insurance, building control, and operational records. Our NICEIC registration means you can rely on the quality and accuracy of every certificate we issue.

We recently completed a three phase power upgrade for a food processing business near Longridge, which had expanded its production capacity significantly and needed additional distribution capacity to support new refrigeration plant and conveyor motors. We phased the works to avoid any production downtime, completing the final tie-in over a planned maintenance shutdown.
