Arc Flash Boundary Calculation Worksheet (PDF)

Free download · A4 (210 × 297mm) — fillable PDF

This A4 fillable PDF form guides you through an arc flash boundary calculation step by step. Fields include: system voltage, available fault current (kA), working distance (mm), electrode configuration (VCB/VCBB/HCB/VOA/HOA), gap between conductors (mm), arc duration (seconds), calculated incident energy (cal/cm²), arc flash boundary distance (mm), PPE category determination, and arc flash label data fields. Each field includes guidance notes referencing IEEE 1584-2018 methodology. Use this worksheet for manual calculations or as a data collection form before running the full calculation in ECalPro's arc flash calculator.

What's Included

Front:Fillable fields: voltage, fault current, working distance, electrode config, gap, arc duration, incident energy result, boundary result, PPE category.
Back:Arc flash label data fields: equipment ID, incident energy, boundary, PPE requirements, date of study.

Frequently Asked Questions

Can I fill this in digitally?

Yes. The PDF has fillable form fields. Open in Adobe Acrobat Reader (free), fill in, save, and print. Works on desktop and tablet.

Does this replace a full arc flash study?

No. This worksheet is for manual boundary calculations or data collection. Use ECalPro's arc flash calculator for full IEEE 1584-2018 compliant studies with automated electrode configuration selection.

What standard methodology does this follow?

The worksheet follows IEEE 1584-2018 calculation methodology with NFPA 70E PPE category assignments.

How often is this updated?

Updated when IEEE 1584 methodology or NFPA 70E PPE categories change. Current version reflects IEEE 1584-2018.
