Commercial electrical work operates under a different set of pressures to domestic. Downtime costs money. Work schedules must wrap around trading hours, staff, and customers. Authority and DNSP paperwork has to be right the first time or it holds up fit-out sign-off. SynthWire Electrical (Lic. EC-1985) has worked across retail tenancies, office fit-outs, restaurants, hotels, medical suites, and light industrial spaces. We understand the constraints, we plan around them, and we deliver installations that are neat, compliant with AS/NZS 3000, and built for the load profiles that commercial tenancies actually generate.
Shop and retail fit-outs
A new retail tenancy needs more than power outlets thrown around the walls. Lighting plays directly into customer experience, and the wrong light level or colour temperature costs you sales. We work from your fitout plans — or help you develop them from scratch — to position general-purpose outlets, display circuit power, point-of-sale infrastructure, refrigeration circuits, and feature lighting on separate, well-labelled circuits with correctly-rated protection. Dimmer-compatible LED downlight circuits, track lighting rail feeds, and window display power are all standard for us. We can schedule first-fix cabling before shopfitting begins and return for fit-off once the joinery is in, keeping us clear of the other trades.
Office and professional fit-outs
Open-plan offices, server rooms, and medical consulting suites each have specific load requirements and cable management expectations. Under-floor ducts, in-slab conduit, and cable tray above suspended ceilings are all part of our standard toolkit. We co-ordinate with your data and communications contractor — we do not do IT cabling, but we position and label the electrical infrastructure so they can work efficiently. Dedicated server room circuits with separate protection and appropriate cable ratings, UPS supply points, and metered sub-boards for tenancy cost recovery are all services we regularly deliver for commercial landlords and tenants alike.
Hospitality: restaurants, cafes, and venues
Commercial kitchens are the hardest electrical environment in the hospitality sector. High-draw equipment — three-phase ovens, commercial dishwashers, combi-steamers, cold rooms — on circuits that run flat-out for twelve-plus hours a day, in a hot and humid environment, serviced by staff who are focused on food, not electrical safety. SynthWire designs commercial kitchen circuits to handle sustained rated loads with appropriate derating factors. We specify and install the correct cable sizes, correctly-rated RCDs, and label every circuit clearly so that a new kitchen hand can find the right isolator without guessing. We also handle after-hours emergency call-outs — if a refrigeration circuit trips at 2 am on a Friday and you have a full load of stock at risk, we answer the phone.
Three-phase supply, metering, and DNSP coordination
Many commercial tenancies require three-phase power for large HVAC systems, lifts, commercial kitchen equipment, or manufacturing loads. Upgrading from single-phase to three-phase supply involves a formal application to your DNSP, infrastructure work at the metering point, and a fully designed three-phase distribution board installation. SynthWire manages the DNSP application, designs the distribution board, and installs the supply to AS/NZS 3000 requirements. We also install sub-metering for cost-recovery purposes across multi-tenancy buildings, and can specify and install interval meters where your energy retailer or building management requires them.
Exit and emergency lighting compliance
Exit and emergency lighting is a life safety system, and the AS/NZS 2293 standard requires it to be tested, logged, and maintained on a regular schedule. SynthWire installs and maintains exit and emergency lighting systems for commercial premises, including initial compliance installation, annual and 6-monthly discharge testing, battery and lamp replacement, and the provision of a compliant test log. We also carry out emergency lighting upgrades where premises have been altered or where the existing system fails testing. Compliant emergency lighting is not optional for commercial occupancies, and we make sure yours passes every inspection.

Frequently asked
Yes, and it is the most common arrangement we make with commercial clients. After-hours, weekend, and early morning start times are all part of standard commercial project scheduling for SynthWire. We quote the relevant penalty rates transparently at the start of the project so there are no surprises on the invoice.
Three-phase upgrades involve a formal capacity application to your DNSP, who will assess the network's ability to supply the requested demand at your address. Once approved, we install the appropriate metering infrastructure, upgrade the main switchboard, and wire the three-phase circuits to your equipment. Timeframes depend on DNSP processing, which varies by network but is typically two to six weeks for straightforward applications.
We do. Scheduled preventive maintenance contracts include periodic thermographic inspection of switchboards, RCD trip-time testing, exit and emergency lighting testing to AS/NZS 2293, and a written defect report after each visit. Maintenance contracts give you documented compliance evidence for your insurer and building manager, and they catch deteriorating equipment before it becomes a fault or a fire.
