Three-phase power for heavier loads

Machinery, large motors, industrial equipment, commercial kitchens and higher-power EV charging often need a three-phase supply to run safely and efficiently. We install and upgrade three-phase supplies and distribution, balancing loads correctly across the phases for stable, reliable operation.

Designed for the demand

Three-phase work demands proper design — correct cable sizing, protection, and load balancing — to avoid overheating, nuisance tripping and inefficiency. We engineer the installation around your equipment and future plans, and coordinate any supply upgrade with the DNO.
