Licensed Professional Engineers
Nationwide Arc Flash Studies & NFPA 70E Compliance, Engineered by Licensed PEs
Field-verified data collection, IEEE 1584 incident energy modeling, and equipment labeling — delivered as a sealed report that stands up to an OSHA inspection.
An out-of-date study is a liability you already own
NFPA 70E 130.5 requires that the arc flash risk assessment be reviewed at least every five years, and again after a system change that could affect the results. Three things happen when it isn't.
OSHA citation exposure
Per serious violation under 1910.333. Willful findings run roughly ten times higher, and citations can be written per exposed employee.
Average arc flash injury
Direct medical and litigation cost of one serious burn incident. Before downtime, replacement gear, or what it does to your experience modifier.
Failed compliance audit
Insurers, corporate EHS, and general contractors all ask for the assessment date now. An expired report stalls renewals and holds up work.
Power system studies, one coordinated model
We build your system model once — every additional study reuses it.Arc Flash Study
Incident energy at every bus per IEEE 1584. Labels printed and installed on your equipment.
Short Circuit Analysis
Available fault current at every bus, checked against equipment interrupting and withstand ratings.
Selective Coordination
Time-current curves and settings so a downstream fault trips the nearest device, not the main.
Load Flow & Voltage Drop
Steady-state loading, transformer capacity, and the voltage that reaches the end of a feeder.
Condition Assessment
Infrared thermography under load, plus visual inspection. Findings ranked by severity.
Electrical Design
Power distribution design and load calculations. Permit-ready drawings, sealed for your jurisdiction.
Why facility engineers choose PowerSafe
We are an engineering firm, not a label printer. Every study is collected in the field by our own crew and sealed by the PE who reviewed it.

How an engagement runs
Scope & fixed fee
Send a one-line, a panel schedule, or just a device count. A written fixed-fee proposal comes back within two business days.
Field data collection
Our engineers document every device, conductor, and as-found setting, scheduled around your shutdown window rather than ours.
Sealed report & labels
PE-sealed study, recommended settings, labels installed on the gear. Then we walk your team through what we found.
What clients say
“PSE was super personable and easy to talk to. Their arc flash study was spot on, catching issues we missed and saving my company money. The team was super knowledgeable and efficient, explaining everything clearly. Now we're confident our systems are safe and compliant. Highly recommend them!”
“I am so glad we did this. They saved us money and significantly improved our facility's electrical safety and reliability. Their expertise and clear recommendations made compliance straightforward and effective. Highly recommended.”
“Thank you, Dalton, for working on this project with us. You were a tremendous help to us prepare for our audit coming up.”
Frequently asked
Still have a question? Call (571) 310-6945 and talk to an engineer, not a rep.
NFPA 70E 130.5 requires the risk assessment to be reviewed at least every five years, and sooner whenever a change to the system could affect the results — a new transformer, a new service, or a utility upgrade.
Most of it is collected energized, in appropriate PPE. A few enclosures need a de-energized window. We identify which ones in the proposal so you can plan the outage instead of discovering it mid-visit.
Device count is the main driver, followed by the number of services, voltage levels, and sites. The calculator gives you a budgetary range; the fixed fee comes after a scoping call, and it does not move because we miscounted.
Yes. Every study is reviewed and sealed by a PE licensed in the state where the facility is located.
We print and apply weather-appropriate labels on site, and hand over the print-ready files so you can replace any that get damaged later.
