Commercial
Three phase power supply installations for commercial and industrial properties across Kent, London and the South East.
Three-phase power is essential for many commercial and industrial operations, from heavy machinery and manufacturing to large HVAC systems and EV charging hubs. DCC Electrics designs and installs three-phase power systems across Kent and the South East.
We handle everything from supply upgrades and new three-phase installations to distribution design, circuit protection and ongoing maintenance.
Three-phase electricity delivers power more efficiently than single-phase for high-demand applications. Motors run smoother and more efficiently, large loads are balanced across three conductors, and the overall supply capacity is significantly higher. For businesses with heavy machinery, commercial kitchens, or multiple EV chargers, three-phase power is often essential.
Installing three-phase power requires coordination with your distribution network operator (DNO) for the supply upgrade, careful design of the distribution system, and proper protection selection. We manage the entire process, from initial feasibility assessment and DNO application through to installation, testing, and certification.
For properties with existing three-phase supplies, we design and install new three-phase distribution boards, machine circuits, and balanced loads. We ensure each phase carries a similar load to prevent inefficiency, overheating, and premature equipment failure.

Local Expertise
Kent's industrial and commercial sectors increasingly need three-phase power for manufacturing, logistics, food production, and EV infrastructure. DCC Electrics has installed three-phase systems across Medway industrial estates, Ashford factories, Maidstone commercial kitchens, and Dartford EV charging hubs. We understand the DNO requirements for Kent postcodes, the typical supply configurations, and the load profiles of Kent businesses.

Our Process
We assess your property's existing supply, check the DNO availability, and determine whether your building can accommodate a three-phase supply upgrade.
We prepare and submit the DNO application, design the distribution system, and specify protection devices. We coordinate with the DNO throughout the approval process.
Our team installs the new supply intake, three-phase distribution board, and machine circuits. We balance loads across phases and install proper isolators and protection for each circuit.
We test phase voltages, current balance, insulation resistance, and protection coordination. Full certification and as-built documentation are provided on completion.
Expert Knowledge
Converting from single-phase to three-phase requires DNO coordination and new supply equipment. We manage the entire upgrade, from application to final commissioning.
Robust distribution boards designed for three-phase supplies with proper phase separation, high fault ratings, and circuits rated for industrial machinery and large loads.
Dedicated three-phase circuits for motors, pumps, compressors, and machine tools. Includes direct-on-line and star-delta starter configurations with appropriate overload protection.
High-capacity three-phase supplies for commercial ovens, extraction systems, and refrigeration banks. Proper phase balancing ensures efficient, reliable kitchen operation.
Three-phase power enables 22kW and rapid EV chargers for commercial fleets and workplace charging hubs. We design systems with load management to prevent supply overload.
Three-phase uninterruptible power supplies and generator backup systems for critical operations. We design seamless switchover systems that protect sensitive equipment during outages.
The DCC Difference
Three-phase delivers significantly more power than single-phase, supporting heavy machinery, large HVAC systems, commercial kitchens, and EV charging hubs.
Three-phase motors run smoother, cooler, and more efficiently than single-phase equivalents. Reduced vibration and heat extend motor life and lower maintenance costs.
Proper phase balancing prevents overload on individual conductors, reduces losses, and improves the longevity of both supply equipment and connected machinery.
We handle the entire DNO application and coordination process. Our experience with UK Power Networks ensures smoother approvals and fewer delays.
Three-phase installations provide capacity for business growth, additional machinery, and technology upgrades without requiring further supply changes.
Every three-phase installation is tested for voltage balance, insulation resistance, earth continuity, and protection coordination. Complete certification is provided.
