Arc Flash Studies
Arc-flash hazard analyses performed in accordance with NFPA 70E and IEEE 1584, including system modeling, incident energy calculations, arc-flash boundary determination, PPE guidance, and equipment labeling—built to support compliance and reduce electrical risk.
What’s Included
Technical scope aligned with standard industry practice.
Data Collection
Field collection of nameplate data, protective device details, conductor sizes/lengths, transformer kVA/%Z, utility available fault current (when available), and operating configurations. Optional one-line verification.
Short-Circuit Model
Build and validate the system model to calculate available fault current at key buses and equipment locations, supporting downstream protection evaluation and arc-flash calculations.
Protective Device Evaluation
Review protective device types and settings assumptions for study accuracy. Where applicable, coordination improvement opportunities and clearing-time constraints are identified.
Arc-Flash Calculation
Incident energy and arc-flash boundary calculations per IEEE 1584 methods (as applicable), including working distance assumptions and equipment class considerations.
PPE / Work Planning
Output includes incident energy values and boundaries that support PPE selection and safe work planning in accordance with NFPA 70E practices.
Labeling
Generate arc-flash labels with incident energy / boundary data and key assumptions. Label format can be aligned to site standards where provided.
Deliverables
Clear documentation you can use to support your safety program.
Typical deliverables
- Arc-flash hazard analysis report (study summary + assumptions)
- Incident energy and arc-flash boundary results by equipment location
- Arc-flash labels (print-ready PDF + optional spreadsheet)
- Short-circuit study results (bus fault duties / available fault current)
- Optional: coordination review notes and setting recommendations (scope-dependent)
- Optional: updated one-line diagram (if provided / as scoped)
Process Overview
How a typical arc-flash project is executed.
1) Kickoff + Scope
Define system boundaries, operating modes, deliverables, label format, and site constraints.
2) Field Data Collection
Gather equipment details and verify configurations. Identify missing data early.
3) Model + Calculations
Build the one-line model, run short-circuit and arc-flash calculations, document assumptions.
4) Review
Review results with client. Address operating modes, coordination constraints, and label placement.
5) Labels + Final Package
Deliver print-ready labels and final report package for records and compliance support.
6) Updates
Support revisions after equipment changes, setting updates, or expansions as needed.
