Electrical Cables: Choosing the Right Type for Every Job

Cables are the backbone of any electrical project. Selecting the correct conductor type, size and insulation ensures efficient power delivery and reduces fire risk. From mains wiring to low-voltage runs, matching cable to purpose is critical.

Key selection factors

Decide on conductor material, cross-sectional area and insulation rating based on load, length and environmental exposure. Consider flexible cables for movable appliances and armoured or outdoor-rated types for exposed runs. Voltage drop and current capacity should guide your size choice.

What you'll find

• Mains and twin-and-earth cables for general household wiring.
• Low-voltage and signal cables for lighting, sensors and audio systems.
• Specialist options such as heat-resistant or water-resistant sheathing for demanding settings.

Shopping for cables can be straightforward when you know the requirements. Retailers often list clearance rolls or customer-returned lengths at reduced prices — inspect product condition and certification details before buying. For larger projects, buy a little extra to account for mistakes and future modifications. If in doubt, seek advice from a professional to confirm load calculations and compliance with safety regulations.
