Three Phase Switchboards Brisbane

Three Phase Installations and Upgrades Brisbane

At Precision Electrical & Air, we specialise in three phase power installation for homes, workshops, and commercial properties across Brisbane. As energy demands continue to rise with the use of air conditioning, induction cooktops, solar systems, and industrial machinery, upgrading to a three phase electrical supply ensures stable, efficient, and reliable power for modern appliances and equipment.

Whether you’re setting up a workshop, running multiple high-draw appliances, or preparing your property for future energy use, our licensed electricians provide safe, compliant, and high-quality three phase installations that meet Australian standards.

What Is Three Phase Power?

Three phase power is a more powerful and efficient electrical supply commonly used in commercial and industrial settings, but it’s also increasingly needed in larger homes and energy-intensive environments. Unlike standard single phase power, which delivers power through one active wire and one neutral, three phase power uses three active wires, delivering a more consistent and balanced power load.

This setup is ideal for properties with:

• High-power air conditioning systems
• Solar PV inverters with higher output ratings
• Induction cooktops and electric ovens
• Workshops with welders, compressors, and machinery
• EV chargers or large refrigeration systems

By spreading the electrical load across three phases, your appliances run more smoothly, motors last longer, and power fluctuations are greatly reduced.

Do I Need a Three Phase Power Upgrade?

You may need a three phase power upgrade if you’ve noticed:

• Power tripping when multiple large appliances run at once
• Voltage drop affecting the performance of machinery or air conditioning
• Installing or planning for solar systems over 5kW
• Expanding a commercial kitchen, mechanical workshop, or home renovation
• Preparing for future demand, such as EV charging or commercial machinery

Our team will assess your electrical load requirements, inspect your existing switchboard, and determine whether an upgrade to three phase is needed.
