http://www.hse.gov.uk/fod/infodocs/483_27.pdf Low voltage normally exceeding 50V ac or 120V dc but not exceeding 1000V ac or 1500V dc between conductors, or 600V ac or 900V dc between conductors and earth. High voltage normally exceeding 1000V ac or 1500V dc between conductors, or 600V ac or 900V dc between conductors and earth. Note Some companies and persons use the term "medium voltage" to describe distribution voltages in range 3.3 kV to 72.5 kV to distinguish these from the higher values of voltage associated with transmission systems. There is no International Electrotechnical Vocabulary (IEV) meaning which specifies values; all that is stated is that the upper value lies between 30 kV and 100 kV. The term has not been used in the UK to prevent confusion with the widely understood use of the term for 415 V 3 phase systems. -----Original Message----- From: Peter Tarver [mailto:[email protected]] Sent: 22 February 2012 17:29 To: [email protected] Subject: [PSES] EU wiring code low voltage / medium voltage transition Good morning. In the US, low voltage is considered 600 Vac or less. Medium voltage begins above 600 Vac. In Canada, low voltage is considered 750 Vac or less. Medium voltage begins above 750 Vac. Is there a similar (harmonized or not) voltage level transition in Europe? Is the LVD's 1000 Vac limit that demarc? - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
