20m 15amp Extension Lead | (1.5mm² Core) on Narrow Multi-Reel

UV Stable Flexible Silicone Rubber, Outdoor Rated

This 20m 15amp extension lead features a 1.5mm² core and is a reliable option for general use, including around the home, on worksites, and in many camper trailer setups with modest energy demands. It's still the most common cable size you'll see sold for RV use in Australia, and is completely safe for powering typical appliances like fridges, lights, and chargers.

That said, a recent update to AS/NZS 3001 includes a clause recommending a thicker 2.5mm² core for supply leads over 15 metres when used to power caravans or other habitable structures. This is due to the increased voltage drop that can occur over longer distances. In most real-world scenarios, you're unlikely to notice a difference when using this lead, but technically it no longer meets the ideal specification for this application. If you want to stay fully aligned with the latest standards, or plan to run higher-draw appliances, we recommend using our 2.5mm² version (M2015HS).

Features:

• No kink memory – Highly flexible silicone rubber winds and uncoils easily without fighting against tight coils.
  
• UV stable – The black cable is carbon-infused for long-term UV resistance — the best available formulation for outdoor use.
  
• Waterproof cable jacket – Can be left on the ground in wet weather (note: plugs must not be left uncovered or sitting in water while in use).
  
• Cold-weather friendly – Lays flat and winds smoothly, even in low temperatures.
  
• Clear 15A plug and socket – Allows visual inspection of connections before and during use.
  
• Stackable and tangle-free – Supplied on a Narrow Flat Out Multi-Reel for clean storage and fast setup. Reel is designed to stack neatly with other Flat Out gear.

When to Use This Model

Ideal for general extension use and RV setups where you're running only low-draw appliances like lights, water pumps, fridges or phone chargers. If you’re staying under 15A total draw and not operating several high-load devices at once, this is a practical, lightweight solution.

For high-power setups or stricter caravan park compliance, consider the M2015HS model with a thicker 2.5mm² core.
