Arc Flash Study Cost Guide
What actually drives arc flash study pricing, with realistic ranges by facility size.
Typical Cost Ranges
- Small facility (1 building, <10 panels): $2,000 – $6,000
- Mid-size facility (multiple panels, one site): $6,000 – $20,000
- Large industrial / multi-building campus: $20,000 – $50,000+
These ranges reflect combined short-circuit, coordination, and arc flash analysis — the standard bundled scope most providers quote. A standalone risk assessment on a small number of pieces of equipment can cost significantly less.
What Drives the Price
- Number of buses/panels analyzed — the single biggest cost driver.
- Data availability — if accurate one-line diagrams and nameplate data already exist, cost drops significantly versus requiring a field data-collection visit.
- Facility accessibility — remote or hard-to-access sites add field time.
- Labeling scope — physical label printing/installation is sometimes a separate line item.
Frequently Asked Questions
How much does an arc flash study cost?
Arc flash study costs typically range from $2,000 for a small single-panel facility to $50,000+ for large industrial sites with hundreds of pieces of equipment. Pricing is driven primarily by the number of electrical panels/buses to be analyzed, facility complexity, and whether supporting engineering data (one-line diagrams, equipment nameplate data) already exists or must be field-collected.
How long does an arc flash study take?
Small facilities: 2-4 weeks. Mid-size industrial facilities: 4-8 weeks. Large multi-building sites: 2-4+ months. Timeline depends heavily on field data collection time and engineering firm workload.
How often does an arc flash study need to be updated?
NFPA 70E recommends review at least every 5 years, or sooner whenever there is a significant change to the electrical distribution system (new equipment, utility service changes, major modifications).
What's included in an arc flash study deliverable?
Typically: incident energy calculations at each analyzed point, required PPE category per point, arc flash boundary distances, a short circuit and protective device coordination study (often bundled), and printable/adhesive labels for equipment.
