De-energizing electrical circuits is critical for technician safety, but turning off power alone is not enough. Residual energy from capacitors, batteries, or backup systems can still pose risks. Proper verification using tools like voltage testers, adherence to Lockout/Tagout (LOTO) procedures, and clear physical boundaries help prevent accidents. Employing trained personnel, ensuring adequate lighting, and keeping emergency equipment ready are essential steps. By following these best practices, workers can confidently troubleshoot electrical systems while minimizing hazards.
