Fresno is the largest industrial base in the Central Valley and the one with the widest range of electrical systems — from century-old downtown service equipment to new distribution centers and clean energy projects on the west side.
Who we work with in Fresno County
- Food and beverage processing — the densest concentration of processing plants in the state
- Distribution and logistics centers along the 99 and 41 corridors
- Healthcare facilities, where essential electrical systems carry additional coordination requirements
- Municipal and institutional buildings, water treatment, and campuses
- Solar and battery storage projects across western Fresno County
- Manufacturing in Fresno, Clovis, Selma, Kingsburg, Sanger and Reedley
Utility service upgrades change your numbers
Fresno has seen substantial service upgrades as facilities expand and electrify. When the utility raises available fault current at your service entrance, two things change: equipment that was correctly rated may no longer be, and incident energy at your gear moves. Both are reasons to re-run a study that was accurate when it was written.
Service equipment at other than dwelling units must be field marked with the maximum available fault current and the date of the calculation — and that marking must be verified or recalculated when modifications affect it.
New construction in Fresno
Where Division 26 05 73 appears in your specifications, both a coordination study and an arc flash study are required, normally before equipment is ordered. The electrical inspector can withhold the Certificate of Occupancy until labels are installed, so this belongs on the schedule early rather than in the punch list.
What every study includes
- Short circuit study with equipment rating evaluation
- Protective device coordination with time current curves for every panel
- Incident energy analysis and arc flash boundaries
- Labels meeting NFPA 70E and NEC 110.16, printed and installed
- Report sealed by a California licensed Professional Engineer
Three things to check before you hire anyone
Ask whether a licensed P.E. Electrical Engineer seals the final report. Ask whether every panel appears in the coordination study time current curve plots, or only the main gear. And ask who performs the field data collection — missing conductor lengths and unrecorded breaker settings go straight into the incident energy result.
We send a P.E. Electrical Engineer to collect the data, with an electrician as support to open panel covers. The engineer who has to defend the model gathers its inputs.
Talk to the engineer who does the work
No sales team. You speak directly with a California licensed Professional Engineer about your equipment, your schedule, and what the study will actually cost.
