25m Cable Reel 240V - 4 Socket Thermal Cutout

Who is this for

This cable reel is designed for site operatives, workshop managers, and facilities teams who need to extend 240V power across large indoor spaces from a single mains socket. The 25m cable bridges the gap between a fixed mains point and equipment positioned across a large site floor, warehouse, workshop, or indoor event space where flat extension leads of 5m or less cannot provide the reach required. The thermal cutout provides a safety mechanism for environments where fully unwinding the cable before each use is not always practical, whilst the BS EN 61242 certification confirms the reel meets the standard for temporary power distribution equipment.

Typical applications

• Running 240V power from a mains socket across a construction site floor to power tools, lighting, and equipment at the far end of an indoor working area.

• Distributing power from a single fixed socket across a large workshop or factory floor to multiple pieces of equipment without installing additional fixed sockets.

• Providing temporary power distribution in indoor areas undergoing renovation where fixed socket provision is unavailable or isolated.

• Powering indoor event and exhibition equipment, lighting rigs, display screens, AV equipment, across large floor areas from a single mains connection.

• Running temporary 240V supply to site welfare equipment including kettles, microwaves, and space heaters within a large welfare area or building.

• Providing power to industrial cleaning equipment and floor maintenance machinery requiring reach across large indoor spaces.

How to use

Step 1: Position the reel on a firm, flat surface in a dry indoor location. Check that the full cable path to the working position is clear of pedestrian traffic, vehicle routes, and sharp edges.

Step 2: Unwind the full 25m cable before connecting any load exceeding 4A. If the full cable cannot be unwound and a portion must remain on the drum, all connected loads must total 4A (960W) or less.

Step 3: Insert the 13A plug into the mains socket and switch on. Confirm the neon indicator is illuminated, showing the reel is live.

Step 4: Connect devices to the four sockets. When the cable is fully unwound, combined total load must not exceed 13A (3,120W). When any cable remains on the drum, combined total load must not exceed 4A (960W).

Step 5: If the thermal cutout trips, power cuts and the neon goes off, unplug from the mains immediately, disconnect all devices from the sockets, and allow the reel to cool fully before pressing the red reset button. Do not attempt to reset while the reel is still warm.

Step 6: Before rewinding, switch off and unplug from the mains. Disconnect all devices. Rewind the cable only when the reel is completely de-energised.

Common mistakes

• Running high-wattage tools with cable wound on the drum: connecting a 2,000W power tool or similar to a wound reel exceeds the 4A wound limit immediately. The thermal cutout will trip within minutes, and repeated tripping under these conditions degrades the cutout over time. Unwind the full cable before connecting significant load.

• Resetting the thermal cutout without allowing the reel to cool: pressing reset whilst the reel is still hot will cause it to trip again almost immediately. A full cool-down, which may take 20 to 30 minutes, is required before reset will hold.

• Using in damp, wet, or outdoor conditions: IP20 provides no water protection. Any moisture reaching the cable, sockets, or drum can create an immediate shock hazard. This reel is for dry indoor use only.

• Rewinding the cable whilst still connected to the mains: always disconnect from the mains before rewinding. A live cable being wound onto the drum creates a coiled conductor under voltage, which is a safety hazard.

• Daisy-chaining into another extension lead or reel: not permitted under IET Wiring Regulations. The mains socket connection must be a direct, single plug-in connection.

Safety

This cable reel is certified to BS EN 61242, CE and UKCA marked, Class I. Maximum load when fully unwound: 13A (3,120W). Maximum load when wound: 4A (960W). IP20, no water protection, indoor and dry use only. Do not use outdoors or in damp conditions. Do not exceed load limits regardless of whether the thermal cutout is present. The thermal cutout is a protection mechanism, not a substitute for correct use. Always unplug from the mains before rewinding. This reel must not be used as a permanent wiring installation.

Maintenance

Inspect the full 25m cable length for cuts, abrasion, kinking, or crushing before each use. Pay particular attention to the section nearest the plug and the cable entry point on the reel drum, where wear is greatest. Do not use if any cable damage is visible. Inspect the plug for cracking or damage. After use under load, allow the reel to cool before rewinding. Store in a dry indoor location. If the thermal cutout fails to reset after a full cool-down period, withdraw the reel from service, do not attempt to override the cutout.
