Three Phase Power Installation, Upgrades And Costs in Newcastle & Maitland

At Horsell Electrical, we understand that the choice between single-phase and three phase power is crucial for optimising energy usage in both residential and commercial settings. The electricity grid typically delivers power through either a single-phase or 3-phase system, each defined by the number of required wires. Industries with substantial power demands, such as industrial units, manufacturing, factories, mines, and restaurants, benefit from the efficiency of a 3-phase power system, essential for running multiple high-powered machines like conveyor belts and compressors.

Even for homeowners, the option to install 3-phase power exists, although the majority of homes and small businesses efficiently operate on single-phase power. Common household appliances, including TVs, fridges, freezers, and lights, typically function on a single-phase system. The need for a 3-phase installation arises when integrating substantial equipment, like large ducted air conditioning systems.

• Single-Phase Power - Utilises one distinct wave cycle and requires only one wire for the phase circuit
• 3-Phase Power - Employs three distinct wave cycles, necessitating three power wires. It offers higher power output, making it ideal for running larger appliances and high-powered machinery

Both systems incorporate a neutral wire connecting to the earth, ensuring a pathway back to the switchboard in case of electrical faults, preventing electrocution, structural damage, and fire hazards.

• Increased Power Output - Achieves more power with the same current, resulting in energy savings
• Cost-Effective Operation - Lower operational costs compared to single-phase power
• Continuous Power Supply - Enhances the efficiency of electric motors by providing a continuous power flow
• Equal Power Distribution - Ensures a balanced power distribution, enhancing safety

Horsell Electrical offers 3-phase installation services in Newcastle, Port Stephens, Hunter, and the Cessnock regions. Our skilled electricians specialise in seamlessly upgrading from single-phase to 3-phase systems, distributing the load evenly among the three phases.

The cost of installing a new three phase power supply depends on whether it’s a new installation or an upgrade. Domestic premises and small businesses will have single phase power by default so usually these types of premises are upgrades.

Larger industrial units will often need a fresh install or upgrading their existing 3-phase supply to cope with expansion or changes bigger usage. We usually do a site visit and give an accurate individual quotation based on your needs, but for a single-phase to three-phase upgrade you should expect to pay between $4500 and $6500.
