The average Australian home now contains 17 connected devices, reflecting a significant increase in the reliance on gadgets and appliances. These devices have become integral to our daily lives, from smartphones and laptops to smart home systems and kitchen appliances, leading to a growing demand for more accessible power outlets.
However, while extension leads offer a convenient solution to this problem, they also come with potential safety risks if used incorrectly. Overloading circuits, using damaged leads, or ignoring safety guidelines can result in serious electrical hazards.
In this blog, we will explore safe and compliant ways to extend power outlets using extension leads, ensuring your home remains both functional and secure for you and your family.
An Overview of Extension Leads and Their Limitations
Extension cords and power strips are commonly used in Australian homes to provide power to connected devices. However, improper use of these tools can lead to significant risks. Understanding their intended use and safety requirements is crucial to prevent electrical hazards.
What is an Extension Lead?
An extension lead is a device that allows you to extend the reach of electrical outlets. It is designed for temporary use, helping to power electronic devices when a wall outlet is not within reach. Extension leads should be used cautiously, especially when connecting high-draw appliances like space heaters or gaming consoles.
Common Misconceptions
Many people mistakenly believe that extension leads or power strips can serve as permanent solutions or that daisy-chaining extension cords or plugging multiple extension cords together are safe. This improper use can result in overheating, electrical fires, or electrical shocks.
Outdoor extension cords should be used only for outdoor use to withstand environmental elements.
Australian Standards and Safe Use
To ensure safety, always adhere to Australian electrical safety standards (AS/NZS 3199). Use extension cords with the correct wire gauge for the load, and avoid damaged cords or exposed wires that generate heat and catch fire.
Avoid overloading power boards or power strips; use those with overload protection and surge protectors. Never plug a power strip into another power strip or extension cord. If you notice electrical faults, immediately disconnect the device and use a circuit breaker to prevent accidents.
Selecting the Right Extension Lead
When selecting extension cords and extension leads, it’s crucial to consider the specific needs of your devices and appliances to avoid potential hazards and ensure safety.
Cable Length and Gauge
When choosing the right extension lead, consider both the cable length and gauge. A longer cord requires a thicker cable (lower gauge) to handle the same load as a shorter one. Using a thin extension cord for a high-power device can lead to overheating and even an electrical fire. Select extension cords with a durable, thicker gauge for outdoor use or areas with foot traffic to withstand environmental elements and prevent overheating.
Power Rating
Always check the power rating of an extension lead before connecting too many devices. The total wattage of the appliances plugged in should not exceed the lead’s rating. Overloading an extension cord or power strip with too much power can create a fire hazard and pose significant safety risks. Ensure that extension cords are plugged directly into wall outlets or a power board and not into another cord or power strip.
Surge Protection
Use an extension lead with a built-in surge protector to safely connect sensitive electronic devices like computers or TVs. This feature helps protect against power surges that can damage your devices and lead to electrical fires. For added safety, ensure your surge protector is connected to a single outlet and not daisy-chained with other power boards.
Safe Usage Practices for Extension Leads
Ensuring the safe use of extension leads is essential to avoid fire risks and other safety hazards. Here are key practices to help you safely use extension cords and power strips in your home.
Avoid Overloading
Overloading an extension lead can lead to overheating, posing a severe fire risk. To avoid this, calculate the total load of the connected devices. The formula is simple: Power (Watts) = Voltage (Volts) x Current (Amps).
For example, if you have a 240V extension cord and a device that uses 2 amps, the power consumption is 480 watts. Ensure the total wattage of all devices does not exceed the extension lead’s power rating. Be cautious when using two extension cords together, as this can also lead to overloading and should be avoided whenever possible.
Proper Placement
Proper placement is crucial for safely using extension cords and power strips. Avoid placing them in high-traffic areas where they could be tripped over, causing damage or injury. Keep extension cords away from water sources, such as sinks or bathtubs, to reduce the risk of electrical shock. Never cover an extension lead with rugs or furniture, as this can trap heat and prevent overheating, increasing the likelihood of a fire risk. Always ensure extension cords are placed in well-ventilated areas to minimise safety risks.
Regular Inspection
Regular inspection of your extension leads is vital to maintaining safety. Look for signs of wear and tear, such as frayed wires, exposed conductors, or loose connections. Using a damaged extension cord can cause electrical shorts, increasing the risk of a fire or injury. If you notice any damage, replace the extension lead immediately.
Temporary Use
Remember, extension cords and power strips are designed for temporary use. Relying on them as a permanent solution can create ongoing safety risks. If you frequently use extension leads, consider installing additional power outlets or a power board to better meet your needs.
Common Mistakes to Avoid When Extending Power Outlets
- Using Multiple Extension Leads: Avoid daisy-chaining extension leads, which can overload circuits and significantly increase the fire risk.
- Plugging High-Power Appliances: Never use extension leads for high-power appliances like heaters or air conditioners; these should always be plugged directly into a wall outlet.
- Ignoring Electrical Safety Ratings: Always check the electrical safety ratings on both the extension lead and the devices being plugged in to prevent overloading and safety risks.
- Improper Storage: Store extension leads properly by avoiding tight coils to prevent kinks and damage to the wire.
Alternatives to Extension Leads for Long-Term Solutions
Installing Additional Outlets: Consider installing more power outlets as a safer, long-term solution for homes with insufficient outlets, reducing the need for extension leads.
Power Boards with Overload Protection: Powerboards equipped with overload protection offer a safer alternative to extension leads by preventing circuit overloads.
Contacting a Licensed Electrician: Consult a licensed electrician for expert advice on safely extending power outlets or upgrading your home’s electrical system, ensuring your setup meets safety standards.
