3 Phase Electrical Wiltshire

Three-phase electrical installations require specialist knowledge, careful design and experience with industrial distribution systems. Invisiwire provides professional 3-phase electrical services across Wiltshire, installing and maintaining three-phase supplies for factories, workshops, commercial premises and EV charging systems in Devizes, Calne, Melksham and beyond.

Three-phase power is essential for large electric motors, industrial machinery, commercial air conditioning and high-power equipment. We assess your load requirements, design the distribution system, handle DNO applications for new connections, and install the complete 3-phase infrastructure with full certification.

Our 3-phase fault-finding service uses specialist test equipment to diagnose phase imbalance, motor faults and supply issues quickly and accurately. We understand how production downtime costs money, so we prioritise industrial fault-finding and carry common 3-phase components to resolve most issues on the first visit.

We also install 3-phase EV charging for commercial premises, providing 22kW charge points that charge electric vehicles significantly faster than single-phase alternatives. All work is tested, certified and compliant with network operator requirements and current electrical regulations.
