Questions Answered

3-Phase Power FAQ

The installation cost (switchboard, wiring, circuits) typically ranges from $3,000-$8,000. Western Power charges separately for the supply upgrade — this varies by property. We provide a complete cost breakdown after the assessment.
Typically 4-8 weeks from application to completion. The main variable is Western Power's processing and scheduling for the metering change.

Single-phase delivers power on one active conductor — suitable for most homes. 3-phase uses three active conductors and delivers roughly triple the power capacity — needed for heavy equipment, large AC systems, and 22kW EV chargers.
