THE COMMON FAILURE POINT
Commercial switchboard upgrades are rarely just a board replacement. The risk sits in the coordination: maximum demand, protection, metering, tenant disruption, shutdown windows, board selection, supply authority requirements, compliance documentation and future maintenance.
Each of these decisions affects cost, downtime risk and the long-term reliability of the asset. Treating an upgrade as a one-line trade item is the most common reason commercial switchboard projects run over time, blow budget or leave compliance gaps behind.
Commercial Switchboards owns the whole outcome. From initial review through energisation, documentation and maintenance.

SECTORS WE SERVE
Common property switchboards, strata documentation and committee-friendly reporting for body corporate sites.
Tenancy upgrades, base-building supply, meter panels and future capacity planning for commercial buildings.
MCCs, plant power and distribution boards planned around production downtime and staged works.
Critical load planning, compliance and staged works delivered with minimal disruption to clinical and care environments.
Mining switchboards, HV ring main units, transportable switchrooms and substation works delivered to mine site safety standards and shutdown windows.
Most contractors hand you off between electricians, engineers and manufacturers. We don’t.
Tier-1 manufacturers push their own boards. We specify for your site – Schneider, NHP, IPD or custom build.
General electricians leave you negotiating with the network. We coordinate Energex and Ergon end-to-end.
Generic upgrades require full site shutdowns. We stage works around tenants and trading hours.
Most jobs end with a tick and an invoice. We hand over compliance docs, as-builts and thermal baselines for your records.
Most contractors disappear after energisation. We retain on contract for scheduled inspections and thermal imaging.
A commercial switchboard replacement in Brisbane typically ranges from $15,000 to $250,000 depending on board rating (250A to 4000A+), site complexity, tenant numbers, supply authority requirements and compliance scope. A single-tenant 400A MSB replacement sits at the lower end. A multi-tenant 1600A board with CT metering, Energex coordination and staged shutdown works sits at the higher end. Initial project review confirms accurate scope before commitment.
A commercial switchboard upgrade in Queensland follows five stages: initial project review, site investigation and design coordination, board specification and procurement, installation and energisation, then documentation and handover. Upgrades must comply with AS/NZS 61439 (switchboard standard) and AS/NZS 3000 (Wiring Rules). Supply authority coordination with Energex or Ergon is standard. HV work follows AS/NZS 2067 and requires RPEQ engineering certification. Full project timeline is typically 12 to 20 weeks from review to energised.
A 3-phase commercial switchboard upgrade in Brisbane typically costs $20,000 to $80,000 for a single-tenant site, depending on board rating, switchgear specification and supply authority requirements. CT metering coordination with Energex adds $3,000 to $8,000. Maximum demand calculations, protection coordination and AS/NZS 61439 compliance documentation are included in the base scope. Multi-tenant 3-phase upgrades with staged shutdown windows start higher due to the coordination involved.
Commercial switchboard manufacture typically takes 8 to 12 weeks from board specification to factory completion. Manufacturers in Australia including Schneider, NHP, IPD and accredited custom builders work to AS/NZS 61439 type-tested designs. Lead times depend on switchgear availability, board complexity, tenant metering configuration and protection coordination. Long-lead components like HV ring main units or specialist drawout switchgear can extend manufacture to 14 to 16 weeks. Board procurement runs in parallel with site preparation and supply authority coordination.

Commercial switchboard upgrades involve significantly higher current ratings (typically 250A to 4000A versus residential 63A to 100A), multi-tenant metering coordination, supply authority approvals, AS/NZS 61439 compliance and staged shutdown planning around trading hours or production schedules. Documentation requirements include compliance certificates, as-built drawings, thermal baseline reports and asset register entries. Residential upgrades focus on safety switches and consumer mains compliance. Commercial Switchboards delivers commercial and industrial work only, no residential.
A commercial switchboard upgrade in Brisbane typically takes 12 to 20 weeks from initial project review to energisation. The breakdown is 1 to 2 weeks for review, 1 to 2 weeks for site investigation and design coordination, 8 to 12 weeks for board manufacture, 1 to 2 weeks for installation and testing, then 1 to 2 weeks for Energex coordination and final commissioning. HV substation works and custom multi-tenant assemblies extend timelines. Emergency switchboard works are expedited where stock allows.
AS/NZS 61439 is the Australian Standard for low voltage switchgear and controlgear assemblies. It replaced AS/NZS 3439 in 2016 and is the current compliance reference for all commercial and industrial switchboards in Australia. The standard covers design verification, thermal performance, short-circuit withstand, IP rating and form separation requirements. Commercial switchboards must be specified, manufactured, installed and documented to AS/NZS 61439 to meet electrical safety obligations and insurer requirements.
A commercial site requires an HV (High Voltage) switchboard upgrade when supply authority load limits at LV are exceeded, typically at 800A to 1600A demand. HV supply is required for major industrial sites, large commercial buildings, hospitals, data centres and mining operations. HV switchboard works follow AS/NZS 2067 and require RPEQ-registered electrical engineering certification. Commercial Switchboards delivers HV switchboards, 11kV ring main units and substation works across Queensland.
CT (Current Transformer) metering is the metering arrangement for commercial sites with demand exceeding direct-connect meter capacity, typically above 100A per phase. CT metering is coordinated with Energex or Ergon during a commercial supply upgrade and requires a sealed CT chamber within the main switchboard. CT ratios, accuracy class and metering circuit specifications must match supply authority requirements. CT metering is standard on commercial switchboard upgrades with three-phase loads above 100A.
Shopping centre switchboard upgrades are staged around trading hours to avoid tenant disruption. Major switchboard works are scheduled for after-hours, overnight or during low-traffic weekday windows. Tenant supply changes are coordinated individually with each affected tenant. Energex coordination, sealed changeovers and staged energisation are planned to maintain trading continuity. The work plan, tenant notifications and shutdown windows are documented before commencement and confirmed with centre management.
Body corporate switchboard compliance covers common property switchboard inspection, AS/NZS 61439 compliance certification, thermal baseline reports and committee-friendly documentation. Standard scope includes individual tenant meter compliance, CT metering verification, switchboard condition reporting and insurance-grade asset documentation. Strata committees typically require formal scope reports for committee approval before works proceed. Commercial Switchboards delivers strata-friendly reporting and compliance documentation for body corporate sites across Queensland.
