Extension Leads & Cable Reels

An extension lead, also called an extension cable or cord, is a length of power cable equipped with one or more sockets at one end and a plug at the other end. It allows you to power appliances at a greater distance from the mains power socket than the device’s integrated cable allows. Extension leads offer a simple and effective way to manage various lengths and combinations of wires. Multi-socket extension leads can power multiple devices from a single mains socket.

Types of Extension Leads

Depending on your specific needs and the equipment you're powering, different types of extension leads are available:

Single Extension Leads

Single extension leads only have one socket and are commonly used to provide power to a part of the room where there is no power outlet. They must never be combined in series with other extension sockets or multi-socket adaptors.

Multi-Socket Extension Leads

Multi-socket extension leads (sometimes referred to as multi-gang extension leads) have more than one socket (or gang). They can be used to power multiple devices and increase the number of plugs that can be connected to one mains socket. Some examples include:

Cable Reels / Extension Reels

Cable reels (or extension reels) are a type of industrial extension cord with one or more sockets. They allow you to power devices at a greater distance from the mains socket, with the cable conveniently stored on a reel. Some models offer features like:

• Auto-rewind: Automatically retracts the cable after use.
• Multiple Sockets: Provide power to multiple devices simultaneously.
• RCDs (Residual Current Devices): Protect against electrical shocks in case of a fault.

Extension Leads (Male and Female End)

These standard extension leads have a male plug at one end (to connect to the mains socket) and a female socket at the other end (to connect your appliance).

Trailing Leads (Male End Only)

Trailing leads have a male plug at one end and bare wires at the other, designed to be wired directly into an appliance or electrical system.

Power Strips

Power strips are similar to multi-socket extension leads, but they often come with additional features like surge protection, switches for individual sockets, and USB ports for charging devices.

Safety Precautions

Extension leads are a convenient way to extend the reach of your electrical appliances, but it's important to make sure you are using them safely:

• Never Connect in Series: Extension leads must not be plugged into one another or used in series. This can cause the socket to overload.
• Avoid Overloading: Don't overload sockets by plugging in appliances that exceed the maximum current rating.
• Secure Cables: If extension lead cables are in areas where they could be a hazard, you should fix the cable down or cover it with a protective rubber strip.
• Unwind Cable Reels Fully: When using cable reels, you must unwind the full length of the cable to prevent overheating.

Choosing the Right Extension Lead or Cable Reel

When selecting an extension lead or cable reel, consider the following factors:

• IP Rating: An IP (Ingress Protection) rating defines how effective an electrical enclosure seals against foreign bodies.
• Surge Protection: Surge protection functionality protects the unit and attached appliances from voltage spikes.
• Switched Sockets: Some models come with the option to turn individual sockets on and off.
• Environment: Determine whether you need an indoor or outdoor extension lead, as outdoor leads are designed to withstand harsh weather conditions.
• Length: Choose the appropriate cable length for your needs, avoiding excessive slack or tension.
• Socket Type: Ensure the socket type (e.g., Type G in Singapore) matches your plugs and appliances.
• Amperage Rating: Select a lead with an amperage rating suitable for the appliances you'll be powering. Higher amperage ratings are required for devices with higher power consumption.
• Cable Thickness: Thicker cables (lower AWG gauge) can handle higher currents and are better for longer distances or high-power appliances.
• Safety Features: Consider extension leads with built-in RCDs for added safety, especially in environments with moisture or potential electrical hazards.
