What a 3-Phase Installation Includes

A three-phase installation is a significant electrical project. Here's what we deliver at every stage.

High-Power Capacity

Three-phase supplies deliver up to three times the power of single-phase at the same current, supporting demanding equipment like commercial ovens, large motors, and industrial machinery.

3-Phase Distribution Boards

Purpose-designed distribution boards with correctly rated triple-pole MCBs, RCBOs, and isolators to protect every circuit in your three-phase installation.

Full Circuit Protection

Every three-phase circuit is protected by appropriate overcurrent and earth-leakage devices, ensuring safe operation of high-power equipment and compliance with BS 7671.

Load Balancing

We design the distribution to balance loads evenly across all three phases, maximising efficiency and preventing overload on any single phase.

Industrial Equipment Wiring

Specialist wiring for three-phase machines including commercial kitchen equipment, air conditioning units, compressors, welders, and CNC machinery.

DNO Liaison & Certification

We manage the entire DNO application process and provide full Electrical Installation Certificates and Building Regulations compliance documentation on completion.
