How to Use an Extension Lead Safely

Overview

Extension leads are useful but can be dangerous if used incorrectly. This guide covers safe use of extension leads.

Step-by-Step Fix

1. Before plugging in any appliance, always check the extension lead's maximum rated power against your appliance's power consumption, usually found on its rating plate or in the manual. Ensure the extension lead can safely handle the total wattage of all devices you intend to connect to prevent overload and potential fire hazards.
2. Avoid plugging high-wattage appliances such as heaters, tumble dryers, or dishwashers into an extension lead; these should always be plugged directly into a wall socket. Using an extension lead with such appliances can quickly overload it, causing the cable to overheat and potentially catch fire.
3. Always fully uncoil the extension lead's cable from its drum before use, even if you only need a short length. Leaving the cable coiled can cause a dangerous build-up of heat, leading to overheating and a risk of fire or damage to the lead.
4. Never run extension leads under carpets, rugs, or furniture, as this can trap heat and create a fire risk. It also makes the lead difficult to inspect for damage and can lead to unnoticed wear and tear or crushing, which could expose live wires.
5. Before each use, carefully inspect the entire length of the extension lead's cable, plug, and sockets for any signs of damage. Look for frayed wires, cuts, cracks, exposed copper, or discolouration, and if any damage is found, do not use the lead and replace it immediately.
6. For sensitive electronic equipment like computers, TVs, or sound systems, consider using an extension lead with built-in surge protection. This will help to safeguard your valuable appliances from sudden power spikes and electrical fluctuations, which could otherwise cause irreparable damage.
