Arc Flash Study for Aerospace & Defense Manufacturers
Southern California Torrance · Burbank · El Segundo · Hawthorne
Southern California's aerospace and defense manufacturing corridor — stretching from Torrance and Hawthorne through El Segundo, Manhattan Beach, Inglewood, and up to Burbank and Chatsworth — runs some of the most specialized industrial electrical systems in the country. High-voltage test equipment, cleanroom electrical, large CNC and machining centers, environmental test chambers, and complex manufacturing MCCs all require current NFPA 70E arc flash compliance. Many aerospace facilities are also subject to customer or prime contractor requirements for documented electrical safety programs. Direct Source delivers complete arc flash studies for SoCal aerospace and defense manufacturers.

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 Aerospace & Defense California
Southern California's aerospace and defense manufacturing base is concentrated in a corridor running from the South Bay (Torrance, Hawthorne, El Segundo, Redondo Beach, Inglewood) through LAX-adjacent operations to the San Fernando Valley (Burbank, Van Nuys, Chatsworth, Canoga Park). This corridor includes major tier-1 and tier-2 suppliers, satellite manufacturers, propulsion and avionics testing facilities, and defense electronics contractors.
Aerospace manufacturing electrical environments are significantly more complex than general manufacturing. High-voltage DC and AC test power supplies, environmental test chambers (vibration, thermal vacuum, EMI), large precision machining centers drawing hundreds of kilowatts, cleanroom electrical systems with specialized distribution, and ongoing facility modifications driven by new program wins all contribute to arc flash hazard that evolves faster than in stable production environments.
Many aerospace manufacturers are also subject to customer or prime contractor requirements for documented electrical safety programs — particularly those working on defense programs under DCSA oversight or NASA facilities with facility safety documentation requirements. An up-to-date NFPA 70E arc flash study with labeled equipment is increasingly a contractual expectation, not just a regulatory one.
Direct Source serves aerospace and defense manufacturers throughout Southern California, providing complete NFPA 70E arc flash studies — field data collection, IEEE 1584 calculations, single-line diagram updates, and arc flash label installation — with experience in production, test, and R&D electrical environments.

FAQ
Common Questions
Do Southern California aerospace manufacturers need arc flash studies?
Yes. Any California aerospace or defense manufacturer with electrical equipment at 50V or above requires arc flash risk assessment under NFPA 70E and Cal/OSHA Title 8. Many prime contractor and defense program safety requirements also mandate documented arc flash compliance. Call (562) 396-9924.
Do aerospace test facilities need separate arc flash studies from the main plant?
Yes. Test facilities — particularly those with high-voltage DC/AC power supplies, environmental chambers, or propulsion test cells — present different arc flash hazard profiles than standard manufacturing areas. They should be included in the arc flash study scope, and may require medium-voltage analysis if test power infrastructure operates above 600V.
Do you serve aerospace facilities in Torrance, Burbank, and El Segundo?
Yes. Direct Source serves aerospace and defense manufacturers throughout the SoCal aerospace corridor — including Torrance, Hawthorne, El Segundo, Redondo Beach, Inglewood, Burbank, Van Nuys, Chatsworth, Canoga Park, and the Antelope Valley (Palmdale, Lancaster).
Can arc flash studies satisfy aerospace prime contractor electrical safety requirements?
Yes. Our arc flash studies are documented to NFPA 70E standards and include single-line diagrams, equipment-level incident energy calculations, and labeled equipment — the documentation typically required to satisfy prime contractor or DCSA electrical safety program requirements.
How often should aerospace facilities update their arc flash studies?
NFPA 70E recommends review after significant electrical changes and at least every 5 years. Aerospace facilities win new programs, install new test equipment, and modify facilities regularly — each change can affect incident energy levels. We recommend annual review of which changes have occurred and a study update whenever material changes have been made.
