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 California.
Apex Arc Flash Engineering is a team of electrical engineers dedicated to one focused area of practice: 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.
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.
We calculate short circuit duties, check equipment ratings, and prepare coordination-ready studies so breakers and relays are sized and applied correctly. The goal is to clear faults quickly and avoid unnecessary loss of service.
We create or clean up single line diagrams so they match actual field conditions. Accurate diagrams become the key for any meaningful study and are treated as a deliverable on every project.
We help update existing studies when systems change, review contractor work, and support ongoing safety programs so maintenance and safety staff still know how to use the results.
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.
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.
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.
We focus on facilities where electrical reliability and safety are central to operations, including
Studies are developed with worker safety and system reliability as primary goals.
Assumptions, data sources, and limitations are documented so it is clear what the model represents.
Where issues are found, we provide options that can be implemented through maintenance work, capital projects, or phased upgrades.
Models and drawings are structured so they can be updated as the system changes, reducing the need to restart from zero.
