Under what condition may only qualified persons work on live electrical conductors?

Qualified persons must work on live electrical conductors when voltages are above 50 volts and conditions are not electrically safe. This requirement stems from the understanding that higher voltages increase the risk of electrical shock and arc flash incidents. Qualified persons, who have received specialized training and have the skills necessary to identify and mitigate electrical hazards, are better equipped to handle these dangerous conditions. Under such circumstances, it is critical to ensure that only those with the right expertise are involved, as they can assess the risks and implement safety measures to protect themselves and others. In situations where the voltage is above 50 volts, the potential for severe injury or fatal accidents rises significantly, making it paramount that only qualified individuals perform work on these live conductors.
