Arc Flash Study for Distribution Centers & Logistics
California Warehouses & Fulfillment Facilities
Southern California's distribution and logistics sector is one of the largest in the world — and one of the most actively Cal/OSHA-inspected. Modern fulfillment centers, cross-dock facilities, and cold chain warehouses run 480V and medium-voltage electrical systems: conveyor motor control centers, dock leveler and door electrical, HVAC and refrigeration MCCs, EV charging infrastructure, and high-bay lighting distribution. All require current NFPA 70E arc flash compliance. Direct Source delivers complete arc flash studies for California distribution and logistics facilities — field data, IEEE 1584 calculations, and labels installed.

Main Switchgear & Substations
IEEE 1584 calculations for 480V and 4160V main switchgear, unit substations, and primary distribution equipment.
Dock & Building Electrical
Arc flash studies for dock leveler controls, door operators, compressed air systems, and building electrical in warehouse facilities.
Cold Storage & Refrigeration
Incident energy analysis for cold chain and temperature-controlled distribution facility refrigeration MCCs and compressor electrical.
EV Charging Infrastructure
Arc flash studies for fleet EV charging switchgear, distribution panels, and charging equipment serving logistics vehicle fleets.
Label Installation
NFPA 70E-compliant arc flash labels printed and physically installed on equipment — required for Cal/OSHA compliance.
What Clients Say
Trusted by City of Industry & Los Angeles County Manufacturers
“We were experiencing electrical and PLC problems at our manufacturing plant and needed help ASAP. Direct Source came in the same day, gave us a very fair estimate, found the problem, and fixed it. We got back up and running with little downtime. These guys know what they're doing.”
“We had an unexpected production issue at our facility in City of Industry and Direct Source responded quickly. Their industrial electrician team diagnosed the problem fast and got us back up and running the same day. Professional and dependable.”
“They were professional and prompt, diagnosed the issue quickly, and fixed it at no charge since it was an easy fix. That type of customer service goes a long way in showing how they operate. They will be our FIRST call for the next electrical need.”
Industry Detail
NFPA 70E Arc Flash Study Distribution & Logistics California
California's distribution and logistics sector is anchored by Southern California — the Inland Empire (Ontario, Fontana, Rialto, Eastvale, Moreno Valley, Perris), the LA Basin (Carson, Compton, Gardena, Vernon), the San Gabriel Valley (City of Industry, El Monte), and the Long Beach / Wilmington port corridor. This region contains tens of millions of square feet of active distribution and fulfillment space, with facilities ranging from small cross-dock operations to multi-story, multi-million-square-foot automated fulfillment centers.
Distribution facility electrical has grown dramatically more complex in recent years. Modern fulfillment centers run conveyor sortation MCCs drawing hundreds of amps, high-density EV fleet charging infrastructure at 480V and above, refrigeration and cold storage electrical for perishable operations, and sophisticated lighting control and building management systems — all typically supplied from 480V/4160V main switchgear with significant available fault currents. Many facilities are also expanding or retrofitting existing buildings, frequently without updating arc flash documentation.
Cal/OSHA actively enforces NFPA 70E arc flash requirements at distribution facilities throughout California, particularly as large e-commerce operators have drawn enforcement attention to the Inland Empire corridor. Arc flash labels on electrical equipment are a routine inspection item. Direct Source provides complete arc flash studies for California distribution and logistics facilities, from single-building operations to multi-facility campus studies.
Why Choose Direct Source
Inland Empire SpecialistsWe are based in Santa Fe Springs and serve the full Inland Empire logistics corridor — Ontario, Fontana, Rialto, Eastvale, Moreno Valley, Perris, and beyond.
New & Existing FacilitiesNew distribution builds rarely include arc flash studies in the electrical contract scope. We pick up that gap — quickly and with minimal disruption to operations.
EV Charging & Modern ElectricalNew EV fleet charging infrastructure adds significant electrical load and fault current exposure. We scope arc flash studies to include new EV switchgear and feeder equipment.
Cal/OSHA ReadyDistribution and e-commerce facilities are high-priority Cal/OSHA inspection targets in California. Our studies are structured to satisfy inspection requirements.
Based in Santa Fe Springs, CA
We are centrally located to serve all of Southern California — from the LA Basin to the Inland Empire, Orange County, and beyond.

FAQ
Common Questions
Do distribution centers and warehouses in California need arc flash studies?
Yes. Any California distribution facility with electrical equipment at 50V or above — including warehouses, fulfillment centers, and cross-dock operations — requires arc flash risk assessment under NFPA 70E and Cal/OSHA Title 8. Call (562) 396-9924.
Do new distribution facilities need arc flash studies?
Yes. New construction rarely includes arc flash studies in the original electrical contract. Facilities go live without arc flash documentation — creating immediate Cal/OSHA exposure for the operator. We frequently onboard new facilities within the first year of operations.
Do you serve Inland Empire distribution facilities?
Yes. Direct Source serves distribution centers, fulfillment facilities, and logistics warehouses throughout the Inland Empire — Ontario, Fontana, Rialto, Rancho Cucamonga, Eastvale, Moreno Valley, Perris, San Bernardino, and all surrounding cities.
How long does an arc flash study take for a large fulfillment center?
A large fulfillment center with multiple MCCs and a main substation typically requires 1–3 days of field data collection. Engineering and label production adds additional time. We schedule field work to minimize interference with operations — nights, weekends, and off-shift windows are common.
Does EV charging infrastructure need to be included in the arc flash study?
Yes. Fleet EV charging equipment — switchgear, distribution panels, and charger terminations — should be included in the arc flash study. New high-power chargers represent significant electrical additions that can affect incident energy levels throughout the facility.
