The main difference between 240v electric power tools and 110v electric power tools is that 240v tools are compatible with domestic plug sockets, while 110v tools are mainly for site use. So if you are doing some home DIY, you should opt for the 240v version of the power tool.
If a power tool is not available in 240v, you can still hire it and use it at home, but you will also need to hire a transformer to convert the voltage to 240v.
110v pieces of equipment are used on site, as the risk of fatality in the event of an accident is reduced. On site, isolating transformers are generally used to provide two 55v lines out of phase. This means that 110v tools can be connected up to them and if a cable is accidentally cut, the voltage is halved and the shock is less likely to be fatal. On many sites, 110v is a requirement and 240v tools are simply not allowed. To find out about the rules of a site and what is allowed, it is best to check with the site manager.
When you book power tool hire with National Tool Hire Shops, you can select whether you would like to hire the equipment as 240v or 110v. Some of our power tools are only available in 110v, so if you are hiring for home use you will also need to hire a transformer. You can add a transformer to your order in the online checkout or when booking over the phone.
