RGCI performed an arc flash study and one-line diagram for the five existing buildings electrical power system. Services included on-site field verifications, coordination of existing equipment with the proposed staff, and review of existing drawings to gather required information.

RGCI Provided a Complete One-Line Diagram of Existing Power Distribution Systems, Including:

  1. Utility Transformer
  2. 800A Distribution Panel MDL
  3. 500KVA Transformer BM-1
  4. 800A Panel LV-1
  5. Gutter #1, #2, #3
  6. 200A Office Panel
  7. 200A Panel LV6
  8. 200A Panel LV-3
  9. 400A Panel HV-2
  10. 112.5KVA Transformer
  11. (3) 75KVA Transformers
  12. 100A Panel HV-3
  13. 220KVA Transformer
  14. Machines HMC1, HMC2, HMC3, HMC4, BM1, BM2, BM3, BM4, PM1, PM2, PM3, PM4, VMC6, VMC7
  15. Conductor sizes, overcurrent protection devices for mains and feeders.

Arc Flash Study Included:

  1. Engineering calculations to determine fault currents required for study
  2. Calculate arc-flash incident energy levels and flash protection boundary distances
  3. Provided results in tabular form
    1. Device or bus name, bolted fault and arcing fault current levels, flash protection boundary distances, personal-protective equipment, and AFIE levels
  4. Affix labels provided by your firm to electrical equipment furnished on project
