Arc Flash Study & Analysis Services

Our Impact

  • 10,000+ arc flash and shock hazard labels printed and applied.
  • 100+ field audits and data gathering trips with no injuries or incidents.
  • EasyPower, ETAP & SKM trained staff with 10,000+ hours of software experience.
  • Brought a previously noncompliant facility to full compliance within 3 months of kickoff.
  • Incident energy improvements to achieve levels <8 Cal/cm² to make your workers safe with readily available PPE.
  • Identify equipment requiring additional PPE or even too dangerous to perform live work! 100% of facilities we have studied have equipment that is too dangerous for standard PPE.

Commercial Power Systems Studies

Focused power systems studies for commercial and light industrial facilities. Scoped to your system with no unnecessary overhead, just the analysis you need. The same methodology we apply to industrial facilities, scaled for the commercial projects that don't need a full engineering study.

Under NFPA 70E and CSA Z462, arc flash studies must be reviewed and updated at a minimum of every five years. This is a mandatory requirement, not a guideline. If your facility is overdue, outdated labels are a liability for your team, your equipment, and anyone working on your electrical system.

We handle the full scope: short circuit, protective device coordination, and arc flash hazard analysis. Delivered together, because the results of each inform the others.

Best Fit
  • Commercial buildings
  • Office, retail, and mixed-use facilities
  • Small institutional or light industrial sites
Pricing

Starting at $3,000 CAD for smaller commercial sites.

Small: under 10 panels.

Frequently Asked Questions

Commercial and small-scope studies can start from $3,000 CAD, while industrial facility budgets start at $10,000 CAD and increase based on size and complexity. Multisite programs may lower costs per facility.

See our arc flash study services for more details on pricing.

Anywhere from 3 weeks for a refresh at a small facility, and 16+ weeks for complex studies at large facilities. Timeframes are often driven by:

  1. data and model availability,
  2. access to equipment,
  3. and utility response times.

See our Arc Flash Study Services for more details on timelines.

While it depends on the service you select, we generally need some or all of the following:

  1. SLDs,
  2. equipment lists,
  3. existing power system model,
  4. protective device settings,
  5. utility fault data,
  6. nameplate data,
  7. and facility access for spot verification.

For most facilities with good documentation/record keeping, or new construction, production downtime is not typically required.

In some cases, where a facility or specific equipment has no documentation at all, it might become necessary to plan electrical outages to collect data. These are normally planned around previously scheduled facility shutdowns.

IEEE 1584 2018, NFPA 70E, and CSA Z462 for arc flash. See “Standards we know” for other standards that are usually referenced for completing the short circuit study, coordination study, and considered when providing recommendations.
