Why EV Charging is a Massive Opportunity
The transition to electric vehicles is creating a new electrical specialty. With millions of EVs expected on Australian and NZ roads by 2030, the demand for home, workplace, and public charging infrastructure is exploding.
Residential
Home charging for EV owners. Level 2 chargers in garages and carports. Fastest growing segment.
Commercial
Workplace charging for employee fleets. Apartment buildings and strata installations.
Public
DC fast chargers at shopping centres, service stations, and public locations.
Types of EV Chargers
| Level | Power | Charge Time | Typical Use |
|---|---|---|---|
| Level 1 | 2.4kW (10A) | 40-50 hours | Emergency/portable only |
| Level 2 (7kW) | 7kW (32A) | 8-12 hours | Home charging (most common) |
| Level 2 (22kW) | 22kW (32A 3-phase) | 3-4 hours | Commercial, apartments |
| DC Fast | 50kW - 350kW | 20-60 mins | Public charging stations |
Note: Level 2 (7kW) is the sweet spot for residential installations. Most EVs can't charge faster than 7kW on single-phase power, making this the practical choice for most homes.

What You'll Learn
Electrical Requirements & Installation
Technical Considerations
Supply Capacity
Most homes have 63A or 80A supply. A 7kW charger draws 32A. Consider existing loads—may need supply upgrade or load management system for older homes.
Circuit Requirements
Dedicated circuit with Type B RCD protection. Isolation switch visible and accessible. Cable sizing per AS/NZS 3000 calculations.
Earthing
Many EV chargers require protective earth. TT earthing systems may need modification. Check manufacturer specifications carefully.
Load Management
Dynamic load balancing prevents overloading supply. Essential for homes with limited capacity. Can delay or avoid expensive supply upgrades.
Installation Process
Site Assessment
Check supply capacity, earthing, location, cable routes
Quotation
Provide fixed price including charger, installation, certification
Pre-installation
Order charger, schedule work, arrange supply upgrade if needed
Installation
Install circuit, RCD, isolation switch, charger unit
Testing
Earth fault loop, RCD test, polarity, charger functionality
Commissioning
Configure charger, connect to app, demonstrate to customer
Certification
Issue compliance certificate, provide documentation

Commercial
Workplace charging, fleet installations
Maintenance
Service contracts, repairs, upgrades
Common Installation Challenges
- Supply Capacity Limitations
Older homes often have limited supply. Solutions: Load management systems, supply upgrades, or lower-power chargers.
- Strata Approval Complexity
Apartments require body corporate approval. Develop expertise in strata processes and documentation to win this lucrative market.
- Earthing Issues
Some older installations lack adequate earthing. May need earth electrode installation or system upgrades.
- Network Operator Requirements
Some supply upgrades require distributor approval. Factor in lead times for approvals when quoting.
Safety Considerations
- DC isolation: EV chargers contain DC components. Proper isolation procedures essential.
- Type B RCDs: Required for EV chargers due to DC fault currents. Don't compromise on safety.
- Regular testing: Recommend annual RCD testing to customers. Offer as service contract.
- Manufacturer training: Stay current with specific charger requirements and updates.
