As Sydney's commercial and industrial sectors grow, so do their energy demands. Whether you're running a warehouse, commercial kitchen, manufacturing plant, or a multi-unit office, reliable power is critical. That’s where 3-phase power installation comes in.
At No.1 Sydney Electrical, we’re licensed Level 2 ASP electricians providing expert 3-phase power upgrades and installations for businesses across Greater Sydney. In this guide, we explain what 3-phase power is, who needs it, and how upgrading can boost your business's efficiency, safety, and growth potential.
3-phase power is an electrical distribution method that delivers power through three alternating currents (phases), each set 120 degrees apart. Compared to the standard single-phase system used in homes, 3-phase offers:
This makes 3-phase power ideal for powering industrial equipment, HVAC systems, data centres, elevators, commercial kitchens, EV chargers, and more.
While most homes run efficiently on single-phase power, many commercial and industrial properties in Sydney benefit significantly from a 3-phase setup. You likely need or can benefit from 3-phase power if you operate:
Not sure if 3-phase is right for you? Our licensed electricians can assess your current and future load requirements and recommend the best solution.
3-phase systems distribute the electrical load evenly, reducing stress on your infrastructure. This leads to fewer power fluctuations, voltage drops, or tripped breakers — especially critical in offices and data centres.
Many commercial-grade machines require 3-phase input. Upgrading allows you to install and run industrial appliances, motors, and HVACs at full capacity.
3-phase systems operate more efficiently than single-phase systems for high-load properties. Over time, this can translate to lower electricity bills and reduced maintenance costs.
As businesses grow and energy needs increase — especially with EV charging or solar battery systems — having 3-phase in place helps you scale quickly without the need for disruptive upgrades later.
No.1 Sydney Electrical follows a proven process for safe, efficient 3-phase installations:
All works comply with the NSW Service & Installation Rules and are logged with the network provider for your protection and compliance.
Every 3-phase installation includes a switchboard upgrade to support higher loads and meet safety codes. We install:
A compliant switchboard ensures long-term safety and compatibility with future upgrades like solar or energy storage.
We also handle 3-phase defect rectification, emergency supply upgrades, and full system rewires.
3-phase upgrades vary in price depending on the scope of the work, site conditions, and network fees. On average:
We provide clear, fixed-price quotes with no hidden fees — and we’ll manage your DNSP paperwork for fast approvals.
No. Only a Level 2 Accredited Service Provider (ASP) can legally upgrade the supply from the network to your property.
Some power interruption is required during the installation, but we plan works to minimise disruption and can work after-hours if needed.
Not necessarily. In fact, it often runs more efficiently for larger properties, especially with proper load management.
