3 phase power, as opposed to single-phase power which is used in most homes and smaller businesses, has many benefits for systems which require more power.

Advantages of 3 phase systems include:

  • Provides continuous, consistent electrical power - ideal for the efficient running of electric motors
  • Cheaper to run than a single phase system for large demand properties
  • Cheaper to install - particularly for new commercial applications
  • Ideal for data centres or large electrical installations as it ensures reliable power supply
