Single vs Three-Phase Electrical Systems
Understanding the right electrical configuration for your needs.
Single-Phase Electrical Systems
Standard electrical supply for most homes and small businesses
Single-phase power is the standard electrical supply for residential properties and small commercial operations. It provides 230V AC power through two conductors (live and neutral) and is suitable for most common electrical appliances.
Voltage
230V AC
Maximum Load
Typically 60-100A
Conductors
Live + Neutral + Earth
Power Capacity
Up to 23kVA
Best For:
- Residential homes
- Small apartments
- Small offices
- Retail shops
Residential Single-Phase Installation
230V single-phase • 60A supply • Standard household wiring • SANS compliant
Three-Phase Electrical Systems
High-capacity power for commercial and industrial applications
Three-phase power provides 400V AC through three live conductors, delivering more power with greater efficiency. It's essential for running heavy machinery, large motors, and commercial equipment that requires substantial electrical power.
Voltage
400V AC (phase-to-phase)
Maximum Load
200A+ per phase
Conductors
L1 + L2 + L3 + N + Earth
Power Capacity
Up to 138kVA (100A/phase)
Best For:
- Industrial facilities
- Large commercial buildings
- Workshops with heavy machinery
- Properties with multiple large AC units
Industrial Three-Phase Installation
400V 3-phase • Heavy-duty distribution • Motor control • Factory installation
Single to Three-Phase Upgrades
Upgrading your electrical supply for increased capacity
Many properties start with single-phase power but need to upgrade to three-phase as electrical demands increase. This upgrade requires municipal approval, new Eskom/meter connections, and comprehensive rewiring of the main distribution.
Upgrade Process
- • Eskom/municipal application
- • New meter installation
- • Main DB replacement
- • Circuit redistribution
Typical Costs
- • Municipal/Eskom fees: R5,000-15,000
- • Electrical installation: R15,000-40,000
- • New DB & components: R8,000-20,000
- • Total: R28,000-75,000+
When to Consider Upgrade:
- Adding workshop/equipment
- Multiple large AC units
- Electric vehicle charging
- Converting to commercial use
Single to Three-Phase Upgrade
Eskom application • New meter installation • 3-phase DB • Capacity increase
