| In Europe 2.000.000 fires are reported each year, which represent more than 4000 deaths, and 70000 people hospitalized due to severe injuries. On average, 90% of fires in EU happen in buildings (www.firesafeeurope.eu).
| |
| Electricity is a very regularly identified cause of domestic fires. In homes, 280000 electrical fires occur each year (www.promotelec.com).
| |
| | |
| Depending on the country and the investigation methods, but also depending on the means of identification, the proportions of electrical fires are:
| |
| * 13 % in the United States (www.nfpa.org);
| |
| * 25 % in France (www.promotelec.com)
| |
| * 33 % in Germany (www.ifs-kiel.de);
| |
| * 40 % in Norway (www.sintef.no).

| Electrical fires in low voltage installation may be caused by
| |
| * Overcurrents (overloads and short circuits): see Chapter [[Sizing and protection of conductors ]]
| |
| * earth faults: see [[Protection against electrical fire risks |Protection against fire due to earth faults ]],
| |
| * electric arcs in cables and connections: see [[Protection against electrical fire risks |Protection against arc faults in cables and connections (AFDD)]].
| |
| * or overvoltages (lightning … ) see Chapter [[Overvoltage protection ]],
| |
| | |
| '''Note:''' Electric arcs in assembly are addressed in chapter [[LV Distribution]]
