Hi Folks Greetings from North of the Border. Here in Canada we basically have 3 voltage range systems according to our CEC Part 1: Extra Low Voltage- 1-30V Low Voltage - 31-750V High Voltage- greater than 750V What would be the same under the NEC? I believe that you also refer to Medium voltage and Ultra High Voltage as well? Thanks allot Best regards Len |

Hi Len, In the U.S. nominal voltage ratings for 60Hz electric power systems above 100V are specified by ANSI C84.1 3 System Voltage Classes 3.1 Low Voltage (LV): A class of nominal system voltages 1000 volts or less. 3.2 Medium Voltage (MV): A class of nominal system voltages greater than 1000 volts and less than 100 kV. 3.3 High Voltage (HV): A class of nominal system voltages equal to or greater than 100 kV and equal to or less than 230 kV. 3.4 Extra-High Voltage (EHV): A class of nominal system voltages greater than 230 kV but less than 1000 kV. 3.5 Ultra-High Voltage (UHV): A class of nominal system voltages equal to or greater than 1000 kV. Aloha, Brian |
