About Apex Arc Flash Engineering
Apex Arc Flash Engineering is a niche electrical engineering practice that specializes in power system studies and electrical safety for facilities across California.
We focus on arc flash analysis, short circuit analysis, coordination studies, and single line diagram development, working with owners, facility managers, and design teams who need clear, reliable studies they can trust in the field.
Based in the San Francisco Bay Area and serving sites across Northern California.
Who We Are
Apex Arc Flash Engineering is a specialized engineering practice dedicated to one focused area: arc flash analysis, short circuit analysis, coordination studies, and single line diagram development.
We combine design office experience, field investigation work, and knowledge of current standards to help clients understand how their electrical systems behave during fault conditions and what can be done to reduce risk to people and equipment.
Our goal is to translate those findings into practical recommendations that improve electrical safety, system reliability, and the quality of the facility’s electrical documentation.
What We Do
Arc Flash
Analysis
We perform complete arc flash studies in line with NFPA 70E and IEEE 1584, including system modeling, incident energy and boundary calculations, and preparation of labels and reports that support your safety program.
Short Circuit
Analysis
We calculate available fault current throughout your system and compare it to equipment interrupting and withstand ratings. This identifies overstressed gear and provides the fault data that coordination and arc flash studies rely on.
Coordination
Analysis
We develop time-current curves (TCCs) and recommend breaker and relay settings so the device closest to a fault clears it first. This keeps outages limited to the affected area and balances selectivity with arc flash reduction.
Single Line Diagram Development
We create or clean up single line diagrams and field-verify them against actual conditions. Accurate diagrams are the foundation of any meaningful study and a deliverable on every project.
Lifecycle
Support
We update existing studies as equipment, settings, and utility data change. We also review contractor work and reissue labels where values shift, so your maintenance and safety staff always have current results they can trust.
How We Work
Step 1
Listen And Define The Scope
We start by reviewing your goals, existing drawings, and any prior studies. Together we define which buildings, electrical rooms, and systems will be included so the scope is clear.
Step 2
Collect Data And Build The Model
We gather equipment information from drawings and field visits and build or update a detailed power system model. During this stage we verify ratings and identify obvious gaps or inconsistencies.
Step 3
Analyze, Document, And Review
We run short circuit, coordination, and arc flash calculations, prepare diagrams, settings, and labels, and then review the results with your team before finalizing.
Where We Serve
We focus on facilities where electrical reliability and safety are central to operations, including
- Hospitals, surgical centers, imaging suites, and medical office buildings
- University and college campuses, research labs, and technical training facilities
- Justice and public safety facilities such as jails, courts, and operations centers
- City and county buildings, central plants, and utility or maintenance yards
- Commercial office buildings, laboratories, and mixed use complexes
- Industrial plants, manufacturing lines, warehouses, and distribution centers
- Water, wastewater, and environmental treatment plants and pump stations
- We focus on facilities where electrical reliability and safety are central to daily operations.
Our Approach and Values
Safety and Reliability
Studies are developed with worker safety and system reliability as primary goals.
Technical Clarity
Assumptions, data sources, and limitations are documented so it is clear what the model represents.
Practical Recommendations
Where issues are found, we provide options that can be implemented through maintenance work, capital projects, or phased upgrades.
Long Term View
Models and drawings are structured so they can be updated as the system changes, reducing the need to restart from zero.
