**While devices like this one in our store may be rated for 240V use, we recommend that any decisions around LV be made by qualified technicians that are licensed to work with mains power. That goes for the work itself, it is a legal requirement anyhow. Stay safe and keep to ELV projects, or employ a contractor to help**
