Testing & Power Calculations

Confidence in safety, compliance, and capacity

Commercial electrical work isn’t complete until it’s verified. Whether you’re fitting out a new tenancy, adding new equipment, upgrading switchboards, or expanding operations, testing and power calculations ensure the electrical system is safe, compliant, and capable of handling demand, without nuisance tripping, overload risk, or future limitations.

We provide Testing & Power Calculations for commercial sites, supporting safe installation, upgrade planning, and long-term reliability through structured verification and clear documentation.

What we do

Our services are tailored to the site and scope, and commonly include:

Electrical testing and verification

  • Verification testing following new installs, alterations, and upgrades

  • Circuit integrity checks and protective device validation

  • Fault-finding support where performance is unstable

  • Testing that supports a compliant handover and safer operation

Load assessments and power calculations

  • Assess existing site demand and available capacity

  • Power calculations for new tenancies, fit-outs, and equipment additions

  • Circuit and distribution planning to support modern loads

  • Identification of constraints before they become expensive problems

Planning for upgrades and expansion

  • Capacity planning for additional circuits, HVAC, kitchen equipment, or EV charging

  • Recommendations for switchboard and distribution upgrades where required

  • Strategies to reduce risk and improve reliability without unnecessary spend

Documentation and reporting

  • Clear records of test results and findings (scope dependent)

  • Capacity and load planning notes to support decision-making

  • Practical recommendations for remediation or staged upgrades

Why testing and calculations matter

Prevent overloads and downtime

Load planning reduces nuisance tripping and failures when new equipment is added.

Improve safety and compliance

Proper testing verifies protection devices and circuit safety.

Avoid costly rework

Knowing capacity and constraints early prevents rushed upgrades later.

Support tenancy changes and fit-outs

Power planning ensures new tenants and upgrades can be accommodated properly.

Protect critical systems

Stable power matters for IT, meeting rooms, signage, POS, CCTV, and access control.

Common reasons businesses call us

  • New tenancy fit-out requiring capacity confirmation

  • Switchboard or distribution upgrades needing load validation

  • Adding high-load equipment (HVAC, kitchen gear, machinery, server racks)

  • Ongoing nuisance tripping or unexplained electrical faults

  • Compliance-focused verification after electrical alterations

  • Planning for EV charging readiness at commercial sites

Our process

  1. Scope and site review

    We clarify what needs to be verified, added, or planned.

  2. Testing and assessment

    We test relevant circuits and review protection and distribution.

  3. Power calculations and planning

    Assess capacity, loads, and upgrade pathways.

  4. Reporting and recommendations

    Clear findings and practical next steps.

  5. Implementation support (optional)

    We can deliver the upgrade work or coordinate staging as required.

FAQ

  • What are “power calculations” in a commercial context?

    Power calculations estimate and confirm electrical demand for a site or new equipment, ensuring circuits and switchboards have enough capacity and protection to operate safely and reliably.

  • When should we do a load assessment?

    Before adding major equipment, expanding a tenancy, upgrading HVAC or kitchen gear, or when planning a fit-out. It helps avoid overloads, downtime, and surprise upgrade costs.

  • Do you provide testing after installation work?

    Yes. Verification testing is a key part of compliant electrical work and helps ensure safety and long-term reliability.

  • Can testing help with nuisance tripping and intermittent faults?

    Yes. Tripping can be caused by overload, wiring faults, moisture ingress, failing protection devices, or equipment issues. Testing helps isolate the root cause.

  • Will you provide documentation of results?

    Yes. Scope-dependent, we can provide clear documentation and recommendations for any remedial work or staged upgrades.

  • Can you work alongside our engineer, builder, or project manager?

    Absolutely. Testing and power planning often sit alongside design and project management during fit-outs and upgrades.

  • Can you help plan staged upgrades to reduce disruption?

    Yes. We can recommend a staged approach and coordinate work around operating hours where possible.
