20m 15amp Extension Lead Extra Heavy Duty | (2.5mm² Core) on Original Multi-Reel




This lead combines durability, flexibility, and electrical performance in one user-friendly package for high-draw needs. Featuring a heavy-duty silicone rubber cable with excellent UV resistance and cold-weather handling, it stays easy to use in all conditions and winds neatly onto the included Flat Out Original Multi-Reel.
The 2.5mm² copper core meets the updated AS/NZS 3001.2:2022 standard for supply leads over 15 metres, helping to reduce voltage drop and maintain consistent power; especially important when running high-draw appliances like air conditioners, induction cooktops, coffee machines, and microwaves. If you're setting up a caravan or RV with higher power needs or simply want to ensure full compliance and clean, stable supply, this is the lead to choose.
Features:
-
2.5mm² core heavy duty conductor – perfect for caravans and RVs needing longer reach .
-
Reduced voltage drop – Thicker copper cores reduce electrical resistance and support stable power delivery over longer distances.

LED status indicator in socket – Quickly confirm power status at a glance before plugging in your equipment.

Note: We do not offer the thicker 2.5mm² core on our shorter leads as it is not required for leads 15m or under (the resistance is lower when running a shorter distance so there is nothing to compensate for).
