Frequently asked questions
What is three-phase power and why might my business need it?
Three-phase power is an electrical distribution method that uses three alternating currents (phases) instead of the single phase typically found in residential properties. It delivers more power more efficiently, making it ideal for businesses with heavy machinery, large HVAC systems, or high electrical demand. If your business experiences frequent circuit overloads, has plans for expansion, or uses equipment requiring three-phase power, an upgrade may be necessary.
How disruptive is the installation process to my business operations?
We understand that downtime impacts your bottom line. Our three-phase power installations are carefully planned to minimise disruption. While some power interruption is unavoidable during the final connection, we schedule these during off-hours whenever possible. The majority of the installation work can be completed alongside your normal operations. We provide detailed timelines and work with you to create an installation schedule that accommodates your business needs.
What permits and approvals are needed for a three-phase installation?
Three-phase power installations typically require electrical permits, potential local council approvals, and coordination with your electricity distributor. As Level 2 electricians, we handle the entire approval process, including all necessary paperwork, liaison with authorities, and compliance documentation. Our comprehensive service ensures all installations meet Australian Standards and local regulations, taking the administrative burden off your shoulders.
Will my electricity bills increase with three-phase power?
While three-phase power provides significantly more capacity, it doesn't necessarily mean higher bills. In fact, three-phase systems operate more efficiently, potentially reducing energy consumption for the same workload. Your actual costs will depend on your usage patterns and equipment. During our assessment, we can provide estimates of how the upgrade might impact your energy costs and identify opportunities for efficiency improvements that could offset any increases.
Can my existing property be converted to three-phase power?
Most properties can be converted to three-phase power, though the complexity varies depending on your current infrastructure and location. The process typically involves upgrading your main switchboard, installing new distribution boards, and coordinating with your electricity provider to upgrade the connection to your property. During our site assessment, we'll evaluate your current electrical setup and provide a detailed conversion plan specific to your property's needs.
