What to check before buying an extension lead
Choosing the right extension lead for your home involves more than just picking the longest cable. Here are the key factors to consider.
Cable length and gauge. Longer cables can cause voltage drop, especially with high-power tools. For home use, a 10m or 15m lead is usually sufficient. Thicker cables (with a lower gauge number) handle higher loads better. Look for a minimum of 1.5mm squared cable for general use.
Number of outlets. Consider how many devices you need to plug in. A 4-gang lead is versatile for most tasks, while a 2-gang is fine for simple indoor use. Avoid daisy-chaining multiple extension leads, as this is a fire risk.
Safety features. Look for thermal cut-out, which shuts off power if the lead overheats, and RCD protection, which cuts power in case of a fault. Surge protection is useful for electronics. These features are essential for outdoor or workshop use.
Indoor vs outdoor rating. Outdoor leads should have an IP rating (e.g., IP44) to resist water splashes. Indoor leads lack this protection. Never use an indoor lead outside in wet conditions.
Mistakes to avoid
Using an indoor lead outdoors. This is a common and dangerous mistake. Indoor leads are not weatherproof and can cause electric shocks or fires if exposed to rain or damp.
Overloading the lead. Every extension lead has a maximum wattage rating (usually 3120W for home leads). Plugging in multiple high-power appliances like heaters, kettles, and lawnmowers can exceed this and cause overheating.
Daisy-chaining leads. Connecting one extension lead to another increases the risk of voltage drop, overheating, and tripping breakers. Always plug directly into a wall socket.
Ignoring cable length. A very long lead can reduce power to your tools, causing them to run slower or overheat. Use the shortest lead that reaches your work area.
