Frequently Asked Questions

What is the difference between a 10A and 15A extension lead?

A 10A extension lead is suitable for standard household appliances such as lamps, TVs, and phone chargers. A 15A extension lead has a higher current rating and is designed for power tools, air compressors, and trade equipment that draw more power. Using a 10A lead with a high-draw appliance can cause overheating — always match the lead rating to your equipment.

What is a piggyback extension lead?

A piggyback extension lead has a specially designed plug that allows a second plug to be inserted into the back of it at the power point. This effectively doubles the number of devices you can connect to a single outlet without using a powerboard. They are particularly useful in tight spaces behind furniture or appliances.

Can I use an extension cord outdoors?

Yes, but you should use an extension cord rated for outdoor use. We stock weatherproof extension leads with cord covers and outdoor-rated insulation suitable for gardens, patios, and job sites. Standard indoor extension cords should not be used in wet or exposed outdoor environments as this creates a safety hazard.

What length extension cord do I need?

Choose the shortest extension cord that meets your needs — longer cords can cause voltage drop, which may affect the performance of sensitive equipment. For general household use, 3m to 5m leads are common. For trade and outdoor use, 10m to 20m leads provide greater reach. We stock a range of lengths to suit most applications.

Do you sell replacement plug tops?

Yes. We stock replacement 10A and 15A plug tops (Australian standard) for repairing damaged plugs on appliances, power tools, and extension leads. Note that replacing a plug top involves working with electrical wiring — if you are not confident doing this safely, consult a licensed electrician.
