A non-conducting safety line is required for work on electrical equipment greater than what voltage?

In electrical safety practices, the necessity for a non-conducting safety line is determined by the voltage level of the equipment being worked on. In this scenario, the correct threshold for requiring a non-conducting safety line is set at 300 Volts.

This is important because voltages at or above this level can present a significant danger due to the risk of electrical shock or arc flash hazards. Utilizing a non-conducting safety line helps to mitigate these risks by ensuring that workers are not coming into contact with conductive materials that could facilitate the passage of electricity. At voltages below this threshold, while safety is still important, the requirements for non-conducting lines are generally less stringent, as the risk of severe electrical hazards diminishes.

Maintaining awareness of these voltage limits is crucial for personnel who work with or near electrical systems, as it helps to enforce safe work practices and compliance with industry regulations.
