Frequently asked questions
What is a site transformer used for?
A site transformer steps down 240V mains power to 110V, which is the mandatory safe voltage for power tools on UK construction sites. You plug the transformer into a standard 240V socket and connect your 110V tools, lights, and equipment to the 110V outlets.
What is the difference between this and the continuous rated version?
This is a standard intermittent rated 3kVA transformer, suitable for typical site tool use where loads cycle on and off during normal work. The continuous rated version is designed for equipment that runs non-stop, such as lighting rigs, heaters, or dehumidifiers.
How many 110V outlets does it have?
The transformer has multiple 110V 16A outlets so you can run several tools and lights from a single unit. Check the combined wattage of everything connected and ensure it stays within the 3kVA rating.
Can I use it at home?
You can use it in a domestic property if you need to run 110V tools from a 240V mains supply. Plug it into a standard 13A socket. This is common for DIY projects where trade-grade 110V tools are being used.
Do I need one if my tools are 240V?
No. A transformer is only needed for 110V tools. If all your equipment runs on 240V, you can plug directly into mains sockets. However, 110V is the safety standard on construction sites and most professional contractors use 110V tools.
