Search for an arc flash study provider and you will find everything from Electrician shops, national testing companies to one-person consultancies working entirely from single-line diagrams which never gets verified in the field. The arc flash study determines many things but most importantly the PPE your workers trust with their lives. This guide explains what separates the best arc flash study companies from the rest, the credentials that actually matter, and the questions facility managers should ask before signing a proposal.
What Makes an Arc Flash Study Company One of the Best?
The best providers are engineering firms first. An arc flash study is a power system engineering calculation, so the company performing it should have licensed Professional Engineers responsible for the modeling, the assumptions, and the final stamped deliverable. Beyond licensure, top firms share a common profile:
- Licensed PEs who own the study from data collection through final labels
- Field verification of the electrical system — not desktop-only studies built from old drawings
- Modeling performed to IEEE 1584 and NFPA 70E requirements
- Deliverables that include incident energy values, arc flash boundaries, and compliant equipment labels
- A documented process for study updates as the system changes
- The ability to pair the study with training so workers understand the labels
- Experts in NFPA 70B and implementation of condition assessments.
Why Does Field Data Collection Separate Good Studies From Bad Ones?
A study is only as accurate as the data behind it, and the single most common failure in the industry is modeling from outdated one-line diagrams. Breakers get replaced, settings get changed, and utility available fault current shifts over time. The best companies send qualified field personnel to verify equipment nameplates, protective device settings, and conductor data before an engineer builds the model. Bowtie Engineering collects real system data on site as part of every incident energy study, because a label printed from a bad model gives a worker false confidence, which is worse than no label at all.
What Standards Should the Study Follow?
A credible arc flash study in the United States is built on three interlocking frameworks. OSHA 29 CFR 1910 sets the legal duty to protect workers from electrical hazards. NFPA 70E defines the arc flash risk assessment requirement and the PPE selection method. NFPA 70B defines the electrical equipment condition and frequency of testing to prove equipment is fit for duty, And IEEE 1584 provides the calculation method engineers use to compute incident energy at each piece of equipment. Ask any prospective provider which edition of IEEE 1584 they model against and how they handle equipment configurations the standard does not directly cover. Firms that answer confidently and specifically are the ones doing this work every week.
Should the Same Company Handle Labels, PPE Guidance, and Training?
YES, It helps enormously. A study that ends with a PDF report often dies in a filing cabinet. The best providers close the loop: they install compliant labels on the equipment, translate incident energy values into practical PPE guidance for each task, and train the workforce to read and act on the labels. Bowtie Engineering pairs its studies with onsite NFPA 70E electrical safety training — an 8-hour, instructor-led session capped at 25 participants — so the study becomes a living part of the facility safety program rather than a compliance artifact. Bowtie Engineering also provides revision control and a warranty in their patented BowVue Portal application.
How Do National Firms Compare With Local Consultants?
Local consultants can be excellent for a single small site, but multi-site organizations usually outgrow them quickly. National engineering firms bring standardized methodology, consistent labeling formats across every location, and the capacity to schedule studies around production windows in multiple states. Bowtie Engineering delivers studies nationwide from its Georgia headquarters, supported by licensed PEs, Certified Energy Managers, and NFPA 70E and 70B credentialed staff, with more than 900 programs completed since 2015 and BBB accreditation since 2019. For organizations standardizing safety across a portfolio, that consistency is the deciding factor.
What Questions Should You Ask Before Hiring an Arc Flash Study Company?
A short interview reveals more than a glossy proposal. Ask these before you sign:
- Will a licensed Professional Engineer perform and take responsibility for the study?
- Do you collect field data on site, or model from existing drawings?
- Which IEEE 1584 edition do you use, and how do you document assumptions?
- What do the deliverables include — labels, boundaries, PPE tables, mitigation recommendations?
- Is there a warranty? How do you handle updates when equipment or utility supply changes?
- Can you provide training so our team understands the results?
- Can you make repairs from over duty equipment found in study?
- Can you also do IR thermography?
- Can you also perform Lock Out Tag Out services?
What Red Flags Disqualify an Arc Flash Study Provider Immediately?
Some warning signs are reliable enough to end the conversation early, and facility managers save weeks by watching for them. The clearest pricing by t the square foot before anyone has asked about your electrical system — it means the vendor is selling stickers, not engineering. A provider who promises results without a site visit has told you the data will come from your old drawings, with every error those drawings contain.
- Pricing quoted before anyone asks about your equipment or system
- No licensed Professional Engineer willing to be named as responsible
- A proposal with no field data collection phase at all
- Vague or missing references to IEEE 1584 and NFPA 70E methodology
- No sample report or deliverable available for review before signing
- No answer for what happens when incident energy results come back dangerously high
- Field Technicians not NFPA 70E Qualified
None of these flags requires technical expertise to spot — they surface in the first phone call if you ask direct questions. The inverse is equally useful: providers who volunteer their methodology, name their engineers, and show their deliverables before being asked are signaling exactly the culture you want working on the data your electricians will trust with their lives. Screen hard at the start, and the rest of the engagement tends to take care of itself.
Frequently Asked Questions
How often does an arc flash study need to be updated?
NFPA 70E requires the arc flash risk assessment to be reviewed at least every five years, or whenever a major modification changes the electrical system. Renovations, new equipment, and utility service changes all trigger a reassessment sooner.
Is an arc flash study legally required?
OSHA requires employers to protect workers from electrical hazards, and NFPA 70E — the consensus standard OSHA looks to — requires an arc flash risk assessment where workers may be exposed. In practice, any facility where staff or contractors open energized panels needs a current study.
How long does an arc flash study take?
Timelines depend on facility size and equipment count. The process runs from field data collection through modeling, engineering review, and label installation, and providers like Bowtie Engineering schedule field work around production so operations are not disrupted.
What is incident energy?
Incident energy is the thermal energy, measured in calories per square centimeter, that would reach a worker at a defined working distance during an arc flash event. It is the number that determines the arc rating of the PPE required for the task.
Does Bowtie Engineering work outside Georgia?
Yes. Bowtie Engineering is headquartered in Cumming, Georgia, and performs arc flash studies, Lockout Tagout, NFPA 70B testing, and NFPA 70E training for facilities nationwide, including multi-site programs standardized across every location.
