Extension Lead FAQs

Extension Lead FAQs

This is our comprehensive guide for Extension Lead FAQs! Whether you’re setting up a home office, planning a DIY project, or simply need more power outlets, extension leads are a convenient solution for connecting multiple devices. However, with so many types of extension leads available, it can be difficult to know which one is best for your needs. That’s why we’ve put together this guide to answer some of the extension lead FAQs. From choosing the right type of extension lead to understanding safety guidelines, we’ll cover everything you need to know to use extension leads safely and effectively. Let’s get started

What is an extension lead?

They are a cable with a plug on one end and multiple sockets on the other end. It allows you to plug multiple electrical devices into a single wall socket, giving you extra outlets for your appliances and electronics. Some come with surge protection to prevent damage from power surges, while others have extra features like USB ports for charging devices.

How does an extension cord work?

When you plug them into a wall socket, it effectively extends the number of available outlets for you to use. You can then plug multiple devices into the outlets. It then passes the electrical current from the wall socket to the devices, allowing them to function as normal.

How do I know if a socket is overloaded?

A socket is considered overloaded if too many devices are plugged into it, drawing more current than the socket can safely handle. Signs of an overloaded socket include flickering lights, buzzing or crackling sounds, and the socket feeling warm to the touch. If you suspect that a socket is overloaded, unplug some of the devices and avoid using the socket until you can have it inspected by a licensed electrician.

What is surge protection in an extension lead?

Surge protection is a feature that helps to protect your electrical devices from power surges. Power surges can occur when there is a sudden spike in the electrical current, which can cause damage to your devices. Extension leads with surge protection have a circuit breaker that automatically switches off the power in the event of a surge, helping to protect your devices.

Can you plug an extension lead into an extension lead?

It is not recommended to plug one into another, as this increases the risk of overloading the circuit and creating a fire hazard. If you need more outlets, it’s best to use a single extension lead with enough sockets to meet your needs or use multiple in separate parts of your home or workplace.

How do I choose the right Extension Lead for my Home?

When selecting an extension lead for your home, it’s vital to make informed choices for safety and optimal performance. Here are key factors to consider:

Amperage (Amps): Ensure the extension lead can handle the electrical load of your devices by choosing the appropriate amperage.

Voltage: Select a product with the correct voltage rating to safeguard your devices.

Cable Length: Consider the distance to your devices and choose a cable length that meets your needs.

Number of Outlets/Sockets: Depending on your devices, choose a lead with the right number of outlets.

Safety Features: Prioritise safety by opting for extension leads with surge protection, overload protection, and other safety features.

Choosing the right extension lead is crucial for device safety and home protection. Prioritise these factors to ensure your extension lead meets your needs and exceeds expectations.

Can I use a power extender outside?

Most are not designed for use outside. If you need to use electrical devices outside, it is best to use an outdoor extension lead specifically designed for outdoor use. These are weatherproof and can be safely used in wet or damp conditions.

Using one for a washing machine could result in an overloaded socket and pose a safety risk. It is best to have a dedicated outlet installed for your washing machine by a licensed electrician.

Is it safe to plug a fridge into an extension lead?

It is not recommended to plug a fridge into an extension lead as fridges also require a large amount of power to operate. Using a power strip for a fridge could result in an overloaded socket and pose a safety risk. It is best to have a dedicated outlet installed for your fridge by a licensed electrician.

Can you run a fridge off an extension lead?

It is not recommended to run a fridge off an extension lead. As mentioned above, fridges require a large amount of power to operate, and using an extension cord could result in an overloaded socket and pose a safety risk.

Can you plug kitchen appliances into extension cords?

Yes, kitchen appliances can be plugged into extension cords, but it’s important to make sure the socket is not overloaded. If you need to use an extension lead for your kitchen appliances, it’s best to use one with surge protection and limit the number of appliances you have plugged in at any given time.

How long can you run an extension lead?

There is no set length of time for running an extension lead, as this will depend on the power requirements of the devices you have plugged in and the capacity of the extension lead. However, it is not recommended to use a power extender for an extended period of time, as this could result in an overloaded socket and pose a safety risk.

Does leaving an extension cord plugged in waste electricity?

No, leaving an extension lead cord plugged in does not waste electricity. However, if the devices that are plugged into the extension lead are left on standby or charging, they will continue to consume a small amount of power even when they are not in use.

Can you run an extension lead through a wall?

It is not recommended to run a power strip through a wall as this could pose a safety risk. If you need to extend the reach of an outlet, it is best to have a licensed electrician install an outlet in the desired location.

When should you not use an extension cord?

You should not use an extension cord:

  • If the socket is already overloaded
  • If the extension cord is frayed or damaged
  • If the extension cord is not intended for outdoor use and you are using it outside
  • If the extension cord is not rated for the power requirements of the devices you want to plug in
  • If the extension cord is not properly grounded

How do I know if an extension lead is safe?

You can determine if an extension lead is safe by checking its rating label, which will indicate its maximum current capacity and whether it has been certified for safe use. You can also inspect the extension lead for any signs of damage, such as fraying, exposed wires, or melted insulation, which could indicate that it is unsafe to use.

How many plugs are too many?

The number of plugs that are too many will depend on the current capacity of the socket and the extension lead being used. As a general rule, it’s best to limit the number of devices you have plugged into a single socket and to avoid overloading the socket by using an extension lead that is rated for the power requirements of the devices you want to plug in.

Can you plug an extension lead into a multi-plug?

Yes, it is generally safe to plug an extension lead into a multi-plug or power strip. However, safety should always be a top priority. Ensure that the combined load of devices connected to the extension lead and the multi-plug doesn’t exceed the capacity of the power strip. Overloading can lead to overheating and potential hazards. Regularly inspect all components for wear and damage to maintain safety. If used correctly and within their specified limits, extension leads, and power strips can be a convenient and safe solution to extend your electrical outlets.

What happens if an extension lead gets wet while plugged in?

If an extension lead gets wet while plugged in, there is a risk of electrical shock and potential damage to the extension lead and the devices that are plugged into it. It is important to immediately unplug the extension lead and allow it to dry completely before using it again. If the extension lead has been damaged, it should not be used and should be replaced.

What is the safest extension cord?

The safest extension cord is one that is properly rated for the power requirements of the devices you want to plug in, is in good condition, and is used in accordance with the manufacturer’s instructions. Extension cords with surge protection and ground fault circuit interrupters (GFCIs) are also considered safer than standard extension cords.

How many extension leads are safe to use?

The number of extension leads that is safe will depend on the power requirements of the devices you have plugged in and the capacity of the extension leads being used. As a general rule, it is best to avoid using more than one extension lead at a time and to limit the number of devices you have plugged into a single socket to prevent overloading.

Do extension leads use electricity when not in use?

Extension leads themselves do not consume electricity when they are not in use. They are essentially passive devices that provide a means to distribute electricity from a power source to multiple devices.

However, some power strips or extension leads come with features like surge protection, which may have a small standby power consumption for their internal circuitry. This power usage is typically minimal and is meant to power indicator lights or surge protection components. It’s often referred to as “phantom” or “vampire” power consumption.

Extension leads and cable reels are incredibly useful tools that help us connect multiple electronic devices to a single power source. However, if not used properly, they can also pose serious safety risks. Here are some tips to help you use extension leads and cable reels safely in your home or office:

1. Check the Electrical Rating

Before using an extension lead or cable reel, always check the electrical rating. The electrical rating indicates the amount of power that the lead or reel can handle safely. If you overload the lead or reel with too many devices, it can cause overheating, which can lead to fire hazards. Therefore, make sure that the electrical rating matches the total wattage of the devices you are connecting.

2. Don’t Connect Multiple Extension Leads Together

It can be tempting to connect multiple extension leads together to reach a distant power source. However, this is a dangerous practice that can increase the risk of fire hazards. Instead, use a single extension lead or cable reel that is long enough to reach the power source.

3. Inspect the Lead or Reel Regularly

Inspect the extension lead or cable reel regularly to make sure that it is in good condition. Look for any signs of damage, such as frayed wires, cracks, or exposed conductors. If you find any damage, do not use the lead or reel, and replace it as soon as possible.

4. Don’t Cover Extension Leads or Cable Reels

Covering extension leads or cable reels with carpets, rugs, or furniture can increase the risk of fire hazards. The covering can trap heat and prevent proper ventilation, which can cause the lead or reel to overheat. Therefore, make sure that the leads or reels are placed in a well-ventilated area, away from any obstructions.
