14 metre 110V trailing lead with 32 amp capacity and 2.5mm heavy duty cable. Fitted with hardened plastic plug and socket for site use. Suitable for power tools, transformers and general site equipment.
This Faithfull 110V 32 amp extension lead is built for construction site use where 110V power is the norm. The 14 metre length gives you a genuine working range without needing a second transformer, and the 2.5mm cable handles the current draw that heavier power tools demand. Whether you’re running a site saw, a grinder, or a transformer feeding multiple outlets, this lead is rated to cope without running warm.
The plug and socket are moulded from hardened plastic, which matters more than it sounds. On a working site, leads get dragged, dropped, and stood on. A thin-shell socket doesn’t last long in those conditions. The hardened housing on this lead takes that kind of treatment without cracking, which keeps the connection safe and the lead in service longer.
Why Cable Size Matters on a 32 Amp Extension Lead 110V Setup
Cable cross-section is one of those specs that’s easy to overlook until something goes wrong. A 1.5mm cable can handle lighter loads fine, but if you’re running a power tool with a meaningful draw at the end of a 14 metre run, you’ll see a voltage drop that affects tool performance. The 2.5mm cable in this lead keeps resistance low across the full length, so tools get the voltage they need rather than a slightly anaemic version of it.
This is particularly relevant when the lead is used in conjunction with a 110V transformer. Transformers already step down from 240V, so anything further lost through an undersized cable is working against you. Fitting a 2.5mm lead like this one from the transformer to the tool is the right way to run it.
Plug and Socket Configuration
The lead is fitted with a 110V 16 amp plug and 110V 16 amp socket the standard yellow configuration familiar to anyone who has worked on a UK construction site. This makes it immediately compatible with the transformers and tools already in use on most sites, with no adapters needed. The hardened plastic casing on both ends is designed to take the kind of rough handling that’s inevitable when a lead is in regular use across a job.
At 14 metres, the Faithfull 32 amp 110V trailing lead gives you enough reach to work comfortably across most bays, rooms, or open floor areas without relocating the transformer every time you move. It coils reasonably for storage and transport, and at this price point it’s a sensible item to keep a spare of on a busy site because the day a lead gets damaged is never a convenient one.
Pro Tip: Always uncoil the full length before use under load. Running a coiled 14 metre lead at high current generates heat that builds up in the centre of the coil and shortens the cable's working life.
This 110V trailing lead is a site cable, pure and simple. It's designed for construction environments where 110V is the required voltage for power tools, and where the lead will be moved, dragged, and used hard across a working day.

Not suitable for: This lead is not suitable for 240V mains use it is a 110V site lead only. It should not be used as a permanent fixed installation.
Uncoil the full 14 metres before connecting to the transformer and plugging in any tool. Running the lead coiled under load traps heat in the cable and causes premature deterioration. Plug the lead into the 110V transformer output socket first, then connect the tool or secondary outlet at the far end.
Inspect the plug, socket and cable before each use. Look for damage to the hardened plastic housings, exposed cable, or any sign of heat stress at the connections. A 110V system is safer than 240V mains, but a damaged lead is a problem on any site. Store coiled loosely and keep out of vehicle wheel paths where possible.
Uncoil the full 14 metre length before connecting to any power source
Inspect the plug, socket and cable jacket for damage before each use
Connect the 110V plug into the output socket of a suitable 110V site transformer
Connect the power tool or equipment to the 16 amp socket at the far end
Check that total load on the lead does not exceed the 32 amp rating
After use, allow the cable to cool before coiling and storing
What is the difference between the 1.5mm and 2.5mm versions of this lead?
The 2.5mm cable carries more current with less resistance over the 14 metre length. For heavier power tools angle grinders, site saws, larger drills the 2.5mm version maintains voltage more effectively at the tool end. The 1.5mm version suits lighter loads. If in doubt, use the 2.5mm.
Is this lead compatible with standard yellow 110V site transformers?
Yes. The lead is fitted with the standard 110V 16 amp plug and socket configuration used on UK construction sites. It connects directly to the output sockets on most site transformers without adapters.
Can this lead be used outdoors?
Yes, it is designed for site use which includes outdoor environments. However, it should be kept clear of standing water and checked regularly for cable or housing damage, particularly in wet conditions.
The Faithfull 110V 32 amp trailing lead uses 2.5mm cross-section copper conductor cable, which provides lower resistance over the 14 metre run compared to 1.5mm alternatives. The plug and socket are moulded in hardened plastic, rated for 110V 16 amp site use in line with standard UK construction site requirements. Cable construction is heavy duty and intended for repeated handling in demanding site conditions.
