Cable

Cable size determines how much current (amps) a cable can safely carry and how much voltage drop occurs over distance.

Choosing the correct size is critical for safety and performance.

Common applications include:

• 
  6mm² / 6 B&S – light loads and short cable runs
  
• 
  8mm² / 8 B&S – fridges, DC-DC chargers, medium loads
  
• 
  14mm² / 6 B&S – inverters and dual battery systems
  

For longer cable runs or higher current loads, a thicker cable is always recommended to reduce heat and voltage drop.

Cable sizes may be listed using different measurement standards:

mm² – metric measurement of conductor cross-sectional area

B&S – Australian cable sizing standard

AWG – American Wire Gauge standard

These systems do not convert directly on a 1:1 basis.

Always check the amp rating rather than relying on size names alone when selecting a cable.

The required amp rating depends on your power system and connected devices.

Your cable must be able to safely handle the maximum current draw.

Typical examples:

• 50A Anderson plug systems – commonly use 6–8mm² cables
  
• 120A–135A systems – require 14mm² or larger cables
  
• Inverters – often require high-current cables with minimal voltage drop
  

When in doubt, sizing up provides better safety and long-term reliability.

Cable length directly affects voltage drop and efficiency.

Shorter cables deliver power more efficiently, while longer runs require thicker cables.

Common use cases include:

• 1.5m–2m – inverter wiring kits
  
• 5m–10m – portable power and vehicle setups
  
• 12m+ – caravans, campervans, and off-road installations
  

Always consider both length and current when selecting your cable.

Yes. These power cables are designed for demanding environments, including:

• Dual battery systems
  
• Caravans and campervans
  
• Off-road and 4WD vehicles
  
• Inverter and off-grid power systems
  

They feature durable insulation, flexible twin-core or twin-sheath designs, and automotive-grade materials.
