Referral to authorised HV specialists. Where genuine high-voltage design, switchgear or transformer work is needed, we'll help you find someone properly authorised for it.
Electrical Support for High Voltage Sites
Every job goes to a licensed electrician from our network who provides:
Site power assessments. A look at your property's electrical setup - distribution boards, switchboards, cabling - to flag what's standard scope and what needs specialist HV sign-off.
Power distribution & switchboard support. Upgrades and maintenance for the distribution boards and switchboards that sit alongside high-voltage equipment.
General electrical safety inspections. Routine inspections and testing on the standard electrical side of high-demand sites, to AS/NZS 3000 wiring standards.
Rapid-response electrical repairs. Fast-response repairs for standard electrical faults on sites with high-demand power systems.

Our Process for High-Demand Power Sites
- Site assessment. Our electrician assesses your property's electrical setup and identifies what's standard scope versus genuine HV work.
- Referral where needed. If real high-voltage design, switchgear or transformer work is required, we help connect you with an appropriately authorised specialist.
- Standard electrical work. We handle the distribution boards, switchboards, cabling and safety inspections that fall within a standard licence.
- Testing & compliance. Testing confirms the standard electrical work meets AS/NZS 3000 wiring standards.
- Ongoing support. Scheduled inspections keep the standard electrical side of your site safe and up to date.
Benefits of Upgrading Your Power System
- Improved power efficiency - ensures optimal energy flow and minimises power loss.
- Enhanced equipment protection - prevents electrical surges that can damage expensive machinery.
- Reduced fire risks - upgrades prevent overheating, electrical sparks and overload-related faults.
- Increased system capacity - supports higher power demands as your site grows.
- Supports compliance - keeps the standard electrical work aligned with AS/NZS 3000 wiring standards.
Keeping High-Demand Power Sites Safe
Good practice for any high-demand power site includes:
- Regular inspections to identify potential risks early.
- RCD safety switches on the standard electrical circuits, as required for general electrical safety.
- AS/NZS 3000 wiring standards followed for all standard electrical installation and maintenance.
- Genuine high-voltage components - switchgear, transformers - inspected and maintained only by someone holding the specific HV authorisation for that work.

Frequently Asked Questions
How often should my power system be inspected?
We recommend the standard electrical side of high-demand sites is inspected every 12 months. Genuine high-voltage components should follow your HV specialist's own inspection schedule.
Can you help with a high-voltage system upgrade?
We handle the standard electrical work involved - distribution boards, switchboards, cabling - and can help coordinate with an authorised HV specialist for the rest.
Do you install or design high-voltage systems?
No - genuine HV design, switchgear and transformer work needs authorisation beyond a standard electrical licence. Our network handles the standard electrical work on high-demand sites and can help you find an authorised HV specialist for the rest.
What is considered HV in Australia?
High voltage (HV) refers to voltages above 1,000 volts AC or 1,500 volts DC, as defined by Australian Standards (AS/NZS 3000).
What is the difference between HV and LV systems?
HV systems operate above 1,000V AC, while LV (Low Voltage) systems operate at or below 1,000V AC.
What is a high voltage system?
A high voltage (HV) system is an electrical system designed to transmit or distribute electricity at voltages above 1,000V AC, often used in industrial or utility settings.
