Trial FAQs
Yes, if you’re outside the trial area you can apply for a supply allocation increase at a cost via Western Power’s website. Alternatively, you can authorise your electrical contractor to apply on your behalf.
No. If your premise is in trial area, the increase in supply allocation from 32 Amp to 63 Amp for single phase connections is effective now. If you experience frequent tripping on your property and you have a 32 Amp main switch circuit breaker installed, please contact your electrical contractor to upgrade your device.
The trial means homes and businesses in the area will be able to install a 63 Amp rated main switch circuit breaker, this is an increase from the current 32 Amp supply allocation for single phase connections in regional and rural areas.
| Zone type | 1 phase | 3 phase | Split-phase |
|---|---|---|---|
| Metro and regional centres | 63 Amps (240 volts) | 32 Amps (415 volts) | Not applicable |
| Rural (trial area – refer to the trial area map) | 63 Amps (240 volts) | 32 Amps (415 volts) | 32 Amp, per phase (480 volts) |
| Rural (outside trial area) | 32 Amps (240 volts) | 32 Amps (415 volts) | 20 Amp, per phase (480 volts) |
We’re trialling an increase in rural supply allocations for single phase connections (240V) following a review undertaken to assess regional and rural power supply allocations in-line with community needs and network capacity.
With the accelerated roll-out of Advanced Metering Infrastructure, we have been able to gather more detailed data and information than ever before – allowing us to model current and future regional network usage. The data shows that the existing electrical infrastructure can support an increase in regional load, with network reinforcements to be implemented through our forward planning.
The trial will help to confirm preliminary review findings that a standardised supply allocation across the South West Interconnected System can be managed in a safe and reliable way for community benefit.
