What data should be collected:
- A one-line drawing of all components with nameplate specifications of every device
- Details of the lengths and cross section area of all cables
- Utility information including the minimum and maximum fault currents that can be expected at the entrance to the facility
Once the above data has been collected, a short circuit analysis should be performed, followed by a coordination study. All the data is then processed into NFPA 70E-2000 or IEEE Standard 1584-2002 equations, which produce the required arc flash protection boundary distances and incident energy requirements.
