Frequently Asked Questions (FAQs)

What is a CCEW, and will I receive one for my project?
A Certificate of Compliance for Electrical Work (CCEW) is a mandatory document in NSW that proves your project conforms to Australian Standards. As of March 2026, all CCEWs must be submitted digitally via the BCNSW eCert portal. Lexicon is fully integrated with this system, meaning your compliance data is lodged instantly with the regulator and your electricity provider, giving you immediate, paperless records for your insurance and safety checks.
How do I know if my business needs a 3-Phase power upgrade?
Standard single-phase power is often insufficient for modern commercial operations. You should consider a 3-phase upgrade if you are installing high-capacity ducted air conditioning, commercial-grade kitchens, or industrial machinery. It is also becoming essential for businesses to install on-site EV charging stations for company fleets, as 3-phase power provides the stable, high-voltage current required for rapid charging without overloading your building’s main switchboard. Our team can conduct switchboard testing to make sure that your business won’t fall victim to electrical faults.
What is Power Factor Correction, and can it reduce my operating costs?
Many Sydney businesses are charged based on “apparent power” (kVA) rather than just “real power” (kW). If your facility uses large motors or heavy machinery, you may be paying for wasted energy that doesn’t actually perform work. Power Factor Correction (PFC) involves installing specialised capacitors that balance this ratio. For large-scale sites, a PFC unit can often reduce electricity demand charges by 15% to 20%, effectively paying for itself through lower monthly utility bills.
When is a Level 2 Electrician required versus a standard commercial electrician?
A standard commercial electrician handles the wiring and systems inside your property. However, a Level 2 Electrician (ASP) is required for any work involving the “Point of Attachment”, which is the physical connection between your building and the street’s power network. You will need a Level 2 specialist if you are upgrading your main service lines, installing new commercial smart meters, or repairing overhead or underground power feeds that have been damaged.
What is the difference between Test & Tag and Fixed Wiring Testing?
“Test & Tag” refers to the safety testing of portable appliances such as computers and power tools. “Fixed Wiring Testing” (also known as an EICR) is a far more comprehensive audit of the permanent electrical system hidden behind your walls and ceilings. Using thermal imaging and insulation resistance tests, we identify degraded cables and loose connections that are invisible to the eye, preventing electrical fires and structural failures before they occur.
How can an electrician help my building achieve a higher NABERS or Green Star rating?

Commercial energy ratings are important for property value and tenant retention. We support these goals by executing advanced sub-metering systems that allow you to track and report energy usage by individual floor or department. Additionally, we specialise in DALI (Digital Addressable Lighting Interface) systems that use smart sensors to dim or deactivate lighting based on natural daylight levels and room occupancy, greatly reducing your building’s carbon footprint.
