Log in to access trade discountsA 50m 110V cable reel with two 16A IEC 60309 sockets for large construction sites. It connects to a 110V CTE site transformer and carries 50 metres of yellow cable to reach tools and equipment across wide site areas. Certified to BS EN 61242 16A, CE and UKCA marked, IP44 rated for outdoor use. Maximum load when fully unwound is 1,750W (16A at 110V). The thermal cutout disconnects the circuit automatically if the reel overheats. Always unwind fully before connecting tools.
A 25m reel covers most standard site bays and floor layouts. On larger sites, the transformer is often positioned at the site entrance, welfare unit, or power distribution board. Tools may need to reach 40 or 50 metres away. Using two 25m reels connected together is not safe and is not permitted. A single 50m reel is the correct solution. It reaches twice the distance from a single transformer output without any daisy-chaining.
2 x 16A IEC 60309 sockets: Yellow 16A sockets for 110V CTE site tools. Two tools can run at the same time from one transformer output. The socket geometry prevents connection to 240V equipment.
IP44 rated: Protected against solid objects larger than 1mm and water splashes from all directions. Suitable for outdoor construction site use in normal conditions. Not for sustained rainfall or standing water.
BS EN 61242 16A certified, CE and UKCA marked: Meets the UK and European standard for cable reels. Class I includes an earth conductor throughout the 3 core cable.
Thermal cutout with neon indicator: Cuts the circuit if the reel overheats. The neon goes off when it trips. Cool the reel fully before pressing the manual reset.
50m 1.5mm 3 core PVC cable: Fifty metres covers large site floors, long groundwork runs, and deep excavation areas from a single transformer position. The 1.5mm conductor handles the full 16A load.
Yellow cable and drum: Yellow is the standard site colour for 110V equipment. It makes this reel immediately identifiable on a site where 240V and 110V equipment are in use at the same time.
Iron frame with carry handle: At 7.1kg, the iron frame keeps the reel stable during use. Carry using the handle. Use proper manual handling technique for this weight.

This reel is for site operatives, site managers, and electricians on large construction sites where 110V CTE tools need to run 50 metres from a site transformer. It works well on sites where the transformer is fixed at one end and the work progresses across a large floor plan, trench run, or external groundworks area. Two 16A sockets allow two tools to operate from the same transformer output simultaneously.
Distributing 110V supply from a single transformer across a large construction site floor to power tools at the far end of the building.
Running two 110V tools from a single transformer output on a wide groundworks or civil engineering project where tools need to reach across the full site width.
Providing 110V power in long trench runs on drainage, utilities, or highway projects where the transformer is positioned at the road end.
Powering 110V site lighting and tools across large refurbishment projects on industrial or commercial buildings.
Supplying 110V power to multiple trades working simultaneously at different points along a large new build floor.
Running 110V supply during demolition work on large structures where the transformer must be positioned outside the demolition zone.
Step 1: Position the transformer in a stable, sheltered location. Connect this reel to the 110V transformer output only. Do not connect to a 240V supply.
Step 2: Unwind the full 50m cable before connecting any tools. This is especially important at 50m where heat builds up faster in a wound reel.
Step 3: Connect the 16A IEC 60309 plug to the transformer. Check the neon indicator is lit to confirm the reel is live.
Step 4: Connect site tools to the two 16A sockets. Total load across both sockets must not exceed 1,750W (16A at 110V).
Step 5: If the thermal cutout trips, disconnect from the transformer, remove all tools, and let the reel cool fully before pressing the reset button.
Step 6: Disconnect from the transformer before rewinding. Never rewind while the reel is connected to any supply.
Not fully unwinding before use: at 50m, a wound reel has twice as many turns as a 25m reel. Heat builds between the turns much faster. Always unwind fully before use, even if you only need part of the cable reach.
Connecting two reels together to get more reach: this is daisy-chaining and is not permitted under IET Wiring Regulations. Use a single 50m reel instead.
Resetting the cutout without full cooling: a 50m reel takes longer to cool than a 25m reel. Allow full cool-down before pressing reset.
Using in heavy rain or standing water: IP44 covers splashes, not sustained rainfall. Position the reel under cover where possible.
Connecting to a 240V supply: the IEC 60309 plug cannot fit a standard 240V socket, but do not attempt to adapt or force any connection.
This reel is for use with a 110V CTE site transformer only. Do not connect to any other supply. Certified to BS EN 61242 16A, CE and UKCA marked, Class I. Maximum load when fully unwound is 1,750W (16A). IP44 rated. Do not use in sustained rainfall or standing water. Unwind fully before use. Disconnect from transformer before rewinding. Do not bypass the thermal cutout. At 7.1kg, apply correct manual handling when carrying.
Check the full 50m cable for damage, kinking, and abrasion before each use. Check both ends particularly carefully. Inspect the plug and socket faces for damage or debris. Clean socket shutters after site use. Let the reel cool fully before rewinding after use under load. Store in a dry location. If the thermal cutout does not reset after a full cool-down, remove the reel from service.
Q: When do I need a 50m reel rather than a 25m reel on a construction site?
A: A 25m reel covers most standard site bays and single-floor work areas from a central transformer position. A 50m reel is the right choice when the transformer is at one end of a large site and tools need to reach the other end. It is also better suited to long trench runs, highway sites, and large floor plate new build projects. Always use a single reel of the right length rather than connecting two reels together.
Q: Can I run two tools at full power simultaneously from both sockets?
A: Both sockets share the same 16A (1,750W) maximum. You can connect two tools at the same time, but their combined wattage must stay within 1,750W. Two tools drawing 1,000W each would exceed this limit. Check the power rating on both tools before connecting them together.
Q: What is the wound current risk at 50m?
A: A 50m reel has twice as many turns as a 25m reel when wound. Heat builds up between the turns much faster than on a shorter reel. This is why full unwinding before use is especially important on this product. Running tools on a wound 50m reel will trigger the thermal cutout quickly, and repeated trips accelerate wear on the cutout mechanism. Always unwind fully.
Q: Can I use this reel outdoors in rain?
A: IP44 protects against water splashes from any direction. It does not protect against sustained rain falling directly onto the reel, running water, or standing water. On site, position the reel under a tarpaulin or in a sheltered location when working in wet weather. Do not leave it in standing water or direct sustained rain.
Q: What should I do if the thermal cutout trips?
A: Disconnect from the transformer immediately. Remove all tools from the sockets. Let the reel cool completely before pressing the reset button. At 50m, cooling will take longer than on a 25m reel. Do not rush the reset. If the cutout keeps tripping at loads within the stated limits, take the reel out of service.
Q: Does this reel work without a site transformer?
A: No. This reel runs on 110V AC only. It cannot be connected to the 240V mains supply. A 110V CTE site transformer is required to step the mains voltage down and provide the correct supply. If you need a 240V cable reel, see the CMT 25m and 50m 240V reels (EL225 and EL250).
