For semiconductor fabs, aerospace manufacturers, and high-tech production facilities across Gilbert, AZ, an NFPA 70E arc flash study is not optional — it is the regulatory and ethical foundation of every credible electrical safety program. Delta Wye Electric delivers comprehensive arc flash risk assessments from our Tempe office, engineered specifically for the complex power systems that drive Gilbert's industrial economy.
Gilbert's rapid emergence as a cornerstone of Arizona's Silicon Desert — home to over 20 semiconductor and high-tech manufacturing facilities — means the town's industrial electrical infrastructure is expanding at an extraordinary pace. Facilities operated by companies like ON Semiconductor, Astronics, and major fulfillment operations like Amazon rely on high-amperage power distribution systems where the consequences of an arc flash incident are severe: catastrophic burns, blast injuries, and fatalities. Beyond the human cost, the regulatory exposure is significant. OSHA enforces compliance with NFPA 70E standards, and facilities without a current arc flash hazard analysis face citations, substantial financial penalties, operational shutdowns, and crippling liability in the event of an incident.
An arc flash risk assessment is the foundational step that quantifies the hazard at every point in your electrical system, defines safe work boundaries, and establishes the PPE requirements your personnel need to work safely. Without it, your facility is operating blind — exposed to risks that are both preventable and well-documented by federal regulators. Every day without a compliant study is a day of unnecessary exposure.
Don't wait for an OSHA inspection to reveal the gap — request a compliance consultation today.
A comprehensive NFPA 70E arc flash study is a multi-phase engineering analysis that produces actionable, site-specific safety data for every energized component in your facility. When Delta Wye performs an arc flash study for Gilbert commercial and industrial facilities, the deliverables include:

Gilbert's industrial landscape presents arc flash compliance challenges that are as diverse as the sectors driving the town's economy. Delta Wye's NFPA 70E arc flash study services are built to address the specific electrical hazards found across Gilbert's key industries and business corridors.
Semiconductor Manufacturing: Facilities like ON Semiconductor and the dozens of high-tech fabs clustered across Gilbert's SanTan Business Campus and surrounding zones operate complex, high-density power distribution systems with large transformers, variable frequency drives, and sensitive process loads. Frequent system modifications to support new production lines mean arc flash studies can become outdated quickly, requiring re-analysis after every significant electrical change.
Aerospace Manufacturing: Companies like Astronics rely on precision machining and testing equipment powered by specialized electrical systems. These facilities face unique coordination challenges where protective devices must be carefully tuned to prevent nuisance tripping without increasing incident energy exposure for maintenance personnel.
Logistics and Warehousing: Amazon's fulfillment operations and the growing distribution infrastructure along the Loop 202 corridor depend on extensive low-voltage distribution with high fault current availability. Rapid facility buildouts and seasonal capacity surges create conditions where electrical systems evolve faster than safety documentation.
Bioscience and Research: Gilbert's emerging bioscience sector, supported by proximity to ASU Polytechnic Campus, introduces laboratory-grade power systems with redundant feeds and backup generation that add complexity to fault current analysis and arc flash boundary calculations.
Your industry has specific risks — let Delta Wye engineer a study tailored to your facility.
Delta Wye Electric has been performing industrial electrical work since 1980 — over 45 years of hands-on experience engineering, building, and maintaining the types of power systems we assess in every arc flash study. When you work with Delta Wye, your arc flash risk assessment is performed by our own qualified engineers, not outsourced to a third-party firm unfamiliar with your facility or industry.
This distinction matters. Our engineers don't just model your system and generate a report — they understand the practical realities of protective device coordination, switchgear maintenance, and power distribution design because they work on these systems every day. When your study identifies opportunities to reduce incident energy levels, Delta Wye has the in-house engineering, design, and construction capability to implement those mitigations directly, from protective device upgrades to panel modifications in our UL-certified fabrication shop.
From our Arizona office in Tempe — minutes from Gilbert's industrial corridors — we deliver arc flash studies grounded in deep NFPA 70E and OSHA compliance expertise, backed by a team that treats electrical safety as a professional obligation, not a paperwork exercise.
Work with engineers who build what they study — request your arc flash assessment from Delta Wye.
NFPA 70E requires employers to perform an arc flash risk assessment before any worker performs tasks on or near energized electrical equipment. This standard applies to virtually every commercial and industrial facility in Gilbert — from semiconductor fabs to warehouses — where employees may be exposed to electrical hazards during operation, maintenance, or servicing of equipment.
An arc flash study must be updated whenever significant changes are made to the electrical system, including equipment additions, protective device replacements, or modifications to system configuration. Even without changes, your facility's risk management program should define a review interval — many organizations adopt a five-year cycle, though high-change environments like Gilbert's semiconductor facilities may require more frequent updates.
Compliant arc flash warning labels display the incident energy level, arc flash boundary distance, required PPE category, nominal voltage, and limited/restricted approach boundaries for each piece of equipment. These labels are the last line of defense — they communicate hazard-specific safety requirements directly to the worker at the moment of exposure, eliminating reliance on memory or separate documentation.
Timeline depends on facility size and system complexity. A mid-size manufacturing plant in Gilbert may require two to four weeks from initial data collection through final report delivery, while larger semiconductor or aerospace facilities with extensive distribution systems may take longer. Delta Wye provides a detailed project timeline during the scoping phase so you can plan accordingly.
