Commercial electrical installations demand a different discipline to residential work. Fault currents are higher, loads are more varied, power quality matters more, and a single circuit failure can halt a floor of workers or freeze a point-of-sale system. PrismTech approaches commercial projects as electrical engineering problems first: we conduct proper load calculations, specify correct protection devices for each circuit type, and coordinate our work with other trades so the project stays on programme.
Office and Retail Fit-Outs
A modern commercial tenancy is dense with electrical demand: LED downlighting, server rooms, comms racks, multiple workstation power rails, commercial kitchen equipment, and data cabling infrastructure all drawing from a single metered supply. PrismTech designs each fit-out circuit layout around the tenancy's actual load schedule, not a generic template. We separate sensitive data and AV circuits from general-purpose power, size submains for future expansion, and install clearly labelled distribution boards so facility managers can isolate circuits without hunting through an undocumented board.
We work after hours and on weekends where live tenancies are nearby. Night-shift and weekend scheduling is built into our project plan from day one, not bolted on as a last-minute compromise. Our teams carry sufficient materials to complete sections in a single shift, avoiding the half-finished work that draws complaints from neighbouring businesses.
Three-Phase Power and Energy Efficiency
Most commercial premises are supplied at 400V three-phase (3Ø), and balancing loads evenly across all three phases is both a compliance requirement and a power quality imperative. Unbalanced loads increase neutral current, generate heat in distribution equipment, and can degrade sensitive electronics. PrismTech phase-balances all new and refurbished distribution boards, verifies the supply at the main switchboard, and documents phase allocation in the as-built drawings handed over at project close.
Energy efficiency upgrades frequently deliver measurable payback within 12 to 24 months for commercial operators. PrismTech installs occupancy-sensor controlled lighting circuits, DALI-compatible dimming systems, demand-controlled ventilation wiring, and smart sub-metering infrastructure compatible with building management systems (BMS). We work alongside mechanical contractors and BMS integrators to deliver a coordinated services package.
Maintenance Contracts and Ongoing Support
Commercial premises need predictable electrical maintenance schedules, not reactive repairs. PrismTech offers structured maintenance agreements that cover periodic testing and tagging of portable appliances, thermographic scanning of switchboards to detect hot connections before they cause failures, and AS/NZS 3017 verification testing of fixed installations. These inspections generate dated, signed records that satisfy insurers, WorkSafe auditors, and building owners during tenancy handovers.

Project Documentation and Handover
Every PrismTech commercial project closes with a complete documentation package: as-built single-line diagrams, circuit schedules, Certificate of Compliance, test results, and warranty records. This documentation set is delivered in both PDF and editable format so your facilities team can update it as the tenancy evolves. A well-documented electrical installation significantly reduces investigation time when faults occur and demonstrates due diligence to building inspectors and insurers.
Talk to PrismTech early in your fit-out or refurbishment project — the best time to get power right is before ceilings are installed and walls are clad. Early engagement means fewer surprises on site and a switchboard sized for what you'll actually need, not just what you have today.
Frequently asked questions
Can you work after hours to avoid disruption to our business?
Yes. We schedule commercial work around your trading hours by default. Night shifts and weekend blocks are costed into the project from the start, and our teams carry enough materials to complete sections without return visits that would extend the disruption window.
What is involved in a three-phase power upgrade for a commercial premises?
We start with a load analysis to confirm the existing supply is adequate or identify the required upgrade. Work typically involves replacing the main switchboard, submains cabling, and distribution boards, then coordinating with the network distributor for the supply augmentation. We handle the entire process.
Do you provide test and tag services for portable appliances?
Yes. PrismTech carries out periodic test and tagging of portable electrical equipment to AS/NZS 3760, including issue of individual test tags and a complete asset register. We can schedule these inspections annually or more frequently depending on the environment and insurance requirements.
What documentation will we receive at project completion?
Every commercial project includes as-built drawings, a circuit schedule, Certificate of Electrical Compliance, AS/NZS 3017 test results, and warranty documentation. Files are provided in PDF and a compatible editable format for your facilities records.
