Arc Flash & Coordination Studies

Short-circuit, coordination, and arc-flash hazard studies for commercial and industrial facilities — performed from Tucson, delivered anywhere in Arizona, and backed by the licensed electrical contractor that can self-perform the corrections.

What We Provide

The full study, not just the labels

Every study starts with field data collection at your facility and a model built in industry-standard power-system analysis software — then we run the engineering that tells you what your system will actually do under fault conditions.

Studies & Analysis

  • Short-circuit / fault-current studies — We calculate the available fault current at each bus and panel so equipment ratings can be verified — underrated gear is one of the most common findings in older Tucson facilities.
  • Protective-device coordination — We set breakers and fuses so the device closest to a fault trips first, isolating the problem instead of blacking out the building.
  • Arc-flash hazard analysis — We calculate incident energy and arc-flash boundaries per NFPA 70E and IEEE 1584, and define the PPE categories your electricians need at each piece of equipment.
  • Load and demand studies — We measure and model how the facility actually draws power, so capacity decisions and additions rest on data instead of nameplate guesses.

Deliverables

  • Study report — Findings, code references, and a prioritized list of corrections in plain language an owner can act on.
  • Updated one-line diagram — An accurate, field-verified one-line of the system as it exists today.
  • Protective-device settings sheets — The exact settings for every adjustable breaker and relay, documented for your records and ours.
  • Printed arc-flash labels — Durable equipment labels with incident energy, boundaries, and required PPE — installed on the gear, not handed over in a box.

Why It Matters

Why owners commission a study

An arc-flash study is not paperwork for its own sake — it is how a facility proves its electrical safety program is real.

  • NFPA 70E requires it — the standard calls for the arc-flash risk assessment to be reviewed at least every five years, or whenever the electrical system changes in a way that could affect the results.
  • Insurers and safety programs ask for it — carriers, safety audits, and many GC prequalification packages now expect current arc-flash labels and a coordination study on file.
  • It protects your people — accurate labels and PPE categories are what stand between a qualified electrician and an incident-energy exposure no one priced in.
  • It protects uptime — properly coordinated devices turn a fault into a tripped branch breaker instead of a dark building.

The Design-Build Advantage

The firm that runs the study can fix what it finds

Most study providers hand you a report and leave. We hold Arizona ROC CR-11 Electrical license #276948 alongside our KA Dual Engineering license — so the same firm that builds the model and runs the analysis can self-perform the corrections: dialing in breaker settings, replacing underrated or obsolete gear, and re-labeling the equipment when the work is done. One contract, one accountable team, from finding to fix.

Back to Electrical Engineering
  • Field data collected by working electricians, not just engineers
  • Breaker and relay settings adjusted in-house under CR-11
  • Gear replacement priced and self-performed by the same firm
  • Tucson-based crews, statewide reach across Arizona

Where studies meet the build

Arc-flash and coordination studies usually surface distribution work — and we engineer and self-perform that too. See the full electrical engineering overview.

Is your arc-flash study current?

If your labels are more than five years old — or your system has changed since they were printed — it's time. Call (520) 308-6235 or send us the facility details and we'll scope the study.
