A three-phase connection involves the use of three separate conductors to transmit electricity from the mains supply. The system provides three alternating currents, with three separate electric services, bringing increased levels of efficiency as it can transmit three times as much power as a single-phase power supply, while only needing one additional wire. Wylex fuses and distribution boards have a strong reputation for durability and robust performance and will ensure an effective electrical distribution service for industrial settings.
