This is a short adaptor fly lead. It connects a 32A transformer output socket to a 16A extension lead or 110V tool. The 32A coupler (large female end) goes into the transformer. The 16A plug (small male end) faces out to the extension lead or tool. Maximum current through the fly lead is 16A. IP67 rated, CE, UKCA and RoHS certified.
When you need a fly lead on site
Not every transformer puts a 16A socket where you need it. Sometimes the only available output is 32A. Rather than swapping the transformer or running without power, a fly lead bridges the gap. This one converts a 32A output to a 16A connection in half a metre. You then connect your standard 16A extension lead or tool directly to the 16A plug end and get on with the job.
Key Features
-
32A to 16A adaptor: The 32A coupler plugs into the transformer's 32A output. The 16A plug on the other end accepts any standard 16A 110V extension lead or tool. Maximum current is 16A, set by the 16A plug end.
-
IP67 rated: Fully dust-tight and protected against water immersion to 1 metre for 30 minutes. Suitable for the toughest outdoor site conditions including flooded trenches.
-
CE, UKCA and RoHS certified: Meets UK and European safety and environmental standards.
-
2.5mm cable: Rated for the 16A current that flows through the fly lead.
-
0.5m compact design: Long enough to reach from the transformer socket to the start of an extension lead, without creating unnecessary cable clutter.

Who is this for
Site electricians and operatives who need to connect 16A equipment to a 32A transformer output. It is an adaptor, not a general extension lead. It sits between the transformer and the extension lead or tool.
Typical applications
-
Connecting a 16A site extension lead to a 32A transformer socket where no 16A output is available.
-
Adapting a 32A socket on a site generator or distribution board to run a standard 16A 110V tool.
-
Providing a 16A connection point at the output of a 32A transformer for sites where 16A extension leads are the standard equipment.
How to use
Step 1: Connect the 32A coupler (large female end) to the 32A socket on the transformer, generator, or distribution board. Rotate the locking collar until fully engaged.
Step 2: Connect the 16A plug (small male end) to your 16A extension lead or 110V tool. Lock the collar.
Step 3: Confirm both ends are locked before switching the transformer on.
Step 4: Do not connect equipment rated above 16A to the 16A plug end.
Common mistakes
-
Using this as a general extension lead: it is 0.5m and designed as an adaptor only. Run a 16A extension lead from the 16A plug end for actual reach.
-
Connecting 32A equipment to the 16A plug end: the fly lead is rated to 16A. Connecting 32A equipment to the 16A output end is not safe.
-
Not locking the connectors: IEC 60309 connections must be locked. An unlocked connection can arc under load.
-
Reversing the connections: the 32A coupler goes into the transformer. The 16A plug faces out. Do not reverse this.
Safety
Maximum current through this fly lead is 16A. The 32A coupler connects to the transformer output. The 16A plug connects to the equipment. Do not reverse the connection direction. Do not connect 32A equipment to the 16A end. For 110V CTE systems only. Do not connect to a 240V supply.
Maintenance
Inspect the cable and both connectors before each use. Clean connector faces after site use. Fit connector caps when not in use to maintain IP67 protection. Do not use if the cable or connectors are damaged.
Frequently Asked Questions
Q: Why do I need a fly lead rather than a standard 16A extension lead?
A: A standard 16A extension lead has a 16A plug that connects to a 16A socket. This fly lead is for when only a 32A socket is available on the transformer or distribution board. It converts that 32A socket to a 16A connection point in 0.5m. You then run your 16A extension lead from the fly lead's 16A plug end.
Q: Which end connects to the transformer?
A: The 32A coupler, the larger female socket end, connects to the 32A output on the transformer, generator, or distribution board. The 16A plug on the other end connects to your extension lead or tool.
Q: Can I connect 32A equipment to this fly lead?
A: No. The 16A plug on the output end is the rating limit. Maximum current through the fly lead is 16A. Connecting 32A equipment to the 16A plug end is not safe and must not be done.
Q: What does IP67 mean for a fly lead?
A: IP67 means the connectors and cable are fully dust-tight and can withstand water immersion to 1 metre for 30 minutes. This is higher than the IP44 rating found on most site extension leads. It means this fly lead can be used in flooded trenches and heavy rain without losing protection.
Q: Can I use this with a 240V supply?
A: No. This fly lead is for 110V CTE systems only. The IEC 60309 connectors are specific to 110V.
