as those above 36 kV (36,000 volts), while medium voltage lines are networks with a voltage between 1 and 35 kV (1,000 and 35,000 volts). The 'HV' mark comes from the German term 'Hochfest Vorgespannt' meaning high strength preloaded

Isolation point
A specific, identified device or location on equipment which shall ensure reliable disconnection or separation from an energy source.
Low Voltage
In this GWO training standard, the term low voltage is used to refer to voltages less than those defined as high voltage. The exact voltage designation varies globally depending on where you work.
Use of voltage classifications:
IEC defines LV as voltages normally exceeding 50 V AC or 120 V DC but not exceeding 1000 V AC or 1500 V DC between conductors, or 600 V AC or 900 V DC between conductors and earth. According to the ANSI C84.1-2020: low voltage is between 240 to 600 V and medium voltage is 2.4 to 69kV.
Live known source
Energy source where you know the level of energy (e.g., as part of a circuit, socket, or a hydraulic check/test point).
Suitable PPE is required for all work based on the task risk assessment. In practice the minimum requirement is generally considered to be arc-rated, flame-resistant clothing and protective gear that protects against the heat and burn risks identified in the assessment. For supporting guidance on good working practices on minimum arc flash PPE refer to Annex 5 For clarity where the word ‘must’ is used in this standard it shall have the same meaning as ‘shall’ Refers to a job safety and quality management process and may have other names including, but not limited to, Job Safety Analysis, Safe Work Approach, Task Risk Assessment, Task Plan, etc.
