There are only three levers available to reduce an arc flash event’s potential injury to electrical workers: energy, time, and distance.
Poorly installed medium-voltage cable could result in faults and make troubleshooting those faults much more difficult.
Performing arc-flash studies for low-voltage power distribution equipment can present challenges that require engineering judgement and proper documentation.
Keeping up with standards and regular testing, maintenance, and field service help mitigate arc flash risks.
Understand how the changes to IEEE 1584 impact incident energy and arc flash boundary calculations to know if your arc flash study is still valid.
