About Smokeless Heat Logs

Extension leads are a common fixture in many homes and offices, providing a convenient way to power multiple devices from a single outlet. However, their convenience can quickly turn into a hazard if not used correctly. At NVR Electrical, we’ve seen firsthand the dangers that improper use of extension leads can pose, from electrical fires to dangerous overloads. Here’s what you need to know to keep your home and office safe.

Understanding the Risks

  • Overloading Extension Leads: One of the most common mistakes is overloading an extension lead. This occurs when the combined wattage of the appliances plugged into the lead exceeds its capacity. Overloading can cause the extension lead to overheat and potentially catch fire.
  • Daisy-Chaining Extension Leads: Connecting multiple extension leads together, or daisy-chaining, can lead to similar risks as overloading. This practice can bypass the built-in safety mechanisms designed to prevent overheating, thus increasing the risk of fire.
  • Physical Damage: Regularly using extension leads can lead to wear and tear. Damaged wires or insulation, whether visible or not, can make these leads dangerous. Exposed wiring is a serious hazard that can lead to short circuits, sparking, and fire.
  • Improper Placement: Running extension leads under carpets, through doorways, or in high traffic areas can lead to physical damage and poses a tripping hazard. Heat cannot escape from an extension lead covered by a rug, increasing the risk of overheating.
  • Using Outdoors: Not all extension leads are suitable for outdoor use. Using a non weather resistant extension lead outdoors can expose it to moisture and environmental damage, which can degrade its safety features.

Preventative Measures

  • Right Rating for the Right Equipment: Always check the power requirements of your devices and ensure the extension lead can handle the total load. Do not exceed the wattage rating of the extension lead.
  • One Lead Per Socket: Avoid daisy-chaining extension leads. If you need more outlets, consider having additional permanent sockets installed by a professional.
  • Regular Inspections: Check extension leads regularly for any signs of damage or wear. Look for frayed cords, cracked insulation, or any signs of burning. Replace damaged leads immediately.
  • Proper Storage: When not in use, store extension leads in a dry, secure place to avoid physical damage and environmental exposure.
  • Choose the Right Lead for the Right Environment: Use weather-resistant leads for outdoor activities and ensure they are rated for outdoor use.

Recognising Signs of Trouble

It’s vital to recognise the signs that an extension lead is failing:

  • Unusual heat build-up along the lead
  • Discoloration of the plug, socket, or lead
  • Flickering lights or intermittent power when using the lead
  • A burning smell coming from the lead or plug

If you notice any of these signs, disconnect the lead immediately and replace it. Continuing to use a faulty extension lead can be a grave risk.
