Short circuit, arc flash, and coordination studies — one connected model, stamped and delivered.
HeirArc is a professional engineering practice built around power system studies: short circuit analysis, arc flash assessments, and protective device coordination. PE-licensed in Washington and Missouri, with a California application under review.
Why one connected study, not three handoffs.
Short circuit, arc flash, and coordination results depend on each other. HeirArc builds all three from a single system model, so the numbers stay consistent from the first fault current calculation to the final breaker setting — and your questions go straight to the engineer of record, not a support queue.
- Specialist, not generalistPower system studies are the whole practice — short circuit, arc flash, and coordination for industrial and commercial facilities, not a sideline next to design work.
- Licensed in two statesActive PE licenses in Washington and Missouri, with a California application under review.
- Direct engineer accessYou work with the engineer who builds and stamps the study — not an account manager relaying questions.
