A 14m 110V CTE extension lead or extension cord in four variants. All are IP44 rated with yellow IEC 60309 connections. Choose 16A or 32A to match your transformer output, and 1.5mm, 2.5mm, or 4.0mm cable for your application.
A 14m 110V CTE extension lead or extension cord in four variants. All are IP44 rated with yellow IEC 60309 connections. Choose 16A or 32A to match your transformer output, and 1.5mm, 2.5mm, or 4.0mm cable for your application.
A 14m 110V CTE extension lead available in four variants. All are IP44 rated, yellow, and fitted with IEC 60309 plugs and sockets. They connect from a 110V site transformer output to a single site tool or piece of equipment. The choice of variant depends on two things: the current rating of your transformer output (16A or 32A) and the cable gauge you need for your application. See the variant comparison table in the specifications tab before selecting.
Most site transformers provide 16A outputs. A 16A lead works for drills, grinders, jigsaws, circular saws, and most portable site tools. If your transformer provides a 32A output, you need a 32A lead. Using a 16A lead on a 32A output is not safe and must not be done.
Within each current rating, cable gauge affects robustness and how much voltage reaches the tool at the far end. A thicker cable has lower resistance. At 14m this difference is small, but for tools drawing close to their maximum rating, a 2.5mm cable on a 16A circuit or a 4.0mm cable on a 32A circuit will maintain slightly higher voltage at the socket end. For most standard site tool use, the 1.5mm 16A (EL114116) is sufficient. For regular heavy use or where the tool draws close to the full rated current, step up to 2.5mm.
IP44 rated across all variants: Protected against solid objects larger than 1mm and water splashes from any direction. Suitable for outdoor construction sites, trenches, and exposed groundwork environments.
IEC 60309 connections: Yellow 16A or 32A IEC 60309 plug and socket. Compatible with all standard 110V CTE site tools and transformers. The connector geometry prevents accidental connection to 240V equipment.
Four cable and rating variants: 1.5mm 16A, 2.5mm 16A, 2.5mm 32A, and 4.0mm 32A. See the comparison table for guidance on selecting the right variant.
Yellow 14m PVC cable: Yellow is the standard site colour for 110V CTE equipment. 14m covers most site bay layouts from a central transformer position.
CE certified, RoHS compliant: Meets CE marking requirements and RoHS environmental standards.

This lead is for site operatives and electricians running 110V CTE tools from a site transformer. The 16A variants suit most standard portable tools. The 32A variants are for equipment or transformer outputs rated at 32A. All four variants are IP44 rated and suited to outdoor construction site conditions including rain splash, groundwork, and trench environments.
Extending the reach from a 16A 110V transformer output to a power drill, angle grinder, or circular saw across a site bay.
Connecting a single 110V site tool to the nearest transformer output when the transformer is further than the tool's own cable will reach.
Running 110V supply into a trench or excavation where the transformer sits at ground level above.
Providing additional reach from a 32A transformer output to large site lighting equipment, compressors, or higher-draw tools.
Use during groundwork, drainage, and civils operations where IP44 protection is needed against water and site debris.
First fix and second fix electrical and mechanical trades requiring 110V tool power at a distance from the transformer.
Step 1: Identify your transformer output current rating before selecting a lead. Match the lead's current rating to the transformer output. Do not connect a 16A lead to a 32A output.
Step 2: Connect the male IEC 60309 plug end to the transformer socket. Align the keyway correctly and rotate the locking collar until fully engaged.
Step 3: Connect the site tool to the female IEC 60309 socket end. Engage and lock the connection before switching on the transformer.
Step 4: Inspect the cable for damage before each use. Do not use if the cable sheath or connectors are damaged. IP44 protection requires the cable and connectors to be undamaged.
Step 5: Disconnect from the transformer before disconnecting from the tool.
Connecting a 16A lead to a 32A transformer output: the lead is not rated for 32A. The cable will overheat. Always match the lead rating to the transformer output.
Connecting to a 240V supply: the IEC 60309 plug does not fit a 240V socket, but do not attempt to force or adapt any connection.
Using a damaged cable: a cut or abraded cable sheath compromises IP44 protection and the safety advantage of the 110V CTE system. Replace the lead immediately if damage is found.
Storing with tight coils: tight coiling causes kinking and can crack the cable sheath over time. Store loosely coiled and keep connector caps fitted when not in use.
These leads are for use with 110V CTE site transformers only. Do not connect to a 240V supply. Match the lead current rating to the transformer output. A 16A lead must not be connected to a 32A output. IP44 rated for outdoor use. Do not use in standing water or sustained rainfall. Inspect cable and connectors before each use. Do not use if damaged. These leads must not be used as permanent wiring.
Inspect the full cable length before each use for cuts, abrasion, and kinking. Check both connector faces for damage and debris. Clean connector faces after site use. Fit connector caps when not in use to maintain IP44 protection at the socket face. Store loosely coiled in a dry location.
Q: What is the difference between the 16A and 32A variants?
A: The current rating must match your transformer output. Most standard site transformers provide 16A outputs, making the 16A lead the right choice for most portable site tools. A 32A output is less common and found on higher-capacity transformers powering larger equipment. Using a 16A lead on a 32A transformer output is not safe. The lead will overheat because its cable is not rated for the higher current. Always check your transformer output rating before selecting a lead.
Q: How do I choose between the 1.5mm and 2.5mm cable on the 16A variants?
A: Both are rated for 16A at 14m. The 1.5mm cable (EL114116) is lighter and easier to handle. It is adequate for most standard site tool use. The 2.5mm cable (EL114216) has lower resistance, so it maintains marginally higher voltage at the socket end when tools draw close to the full 16A. For general site use, 1.5mm is sufficient. If you regularly run tools at or near their maximum rated load, or you prefer a more robust cable, choose 2.5mm.
Q: How do I choose between the 2.5mm and 4.0mm cable on the 32A variants?
A: Both are rated for 32A. The 2.5mm cable (EL114232) is lighter and suits most standard 32A site equipment. The 4.0mm cable (EL114132) has significantly lower resistance. This matters most for high-draw equipment where maintaining voltage close to 110V at the socket end is important for performance and motor longevity. Site lighting rigs, compressors, and similar equipment benefit from the 4.0mm cable on a 32A circuit.
Q: What does IP44 mean for a site extension lead?
A: IP44 means the lead is protected against solid objects larger than 1mm and water splashes from any direction. This makes it suitable for outdoor construction sites, trench environments, and exposed groundwork conditions where rain splash and site water are normal hazards. IP44 does not cover submersion or sustained rainfall falling directly onto the connectors. Keep connector faces facing downward or protected where possible.
Q: Can these leads be used without a site transformer?
A: No. These leads run on 110V AC only and connect to the output of a 110V CTE site transformer. They cannot be plugged into a 240V mains socket. The IEC 60309 plug will not fit a standard 240V BS1363 socket. If you need a 240V extension reel or lead, see the CMT range of 240V cable reels.
Q: What site tools can I run on a 16A 110V lead?
A: Most standard portable site tools are rated for 16A at 110V. This includes angle grinders, power drills, jigsaws, circular saws, belt sanders, and orbital sanders. Check the tool's rating plate for its current draw at 110V before connecting. Do not connect a tool that exceeds 16A to a 16A lead.
