About Our Service Area
Arc Flash Studies Across Riverside County
Riverside County's industrial base spans dramatically different geographic and economic zones. The western Inland Empire — Corona, Norco, Eastvale, and Jurupa Valley — is a major logistics and manufacturing hub connected to the I-15, I-215, and 91 Freeway corridors. Moreno Valley and Perris anchor a massive e-commerce fulfillment cluster including the World Logistics Center. The southwest corridor — Temecula, Murrieta, Menifee, and Lake Elsinore — is rapidly industrializing with distribution, healthcare, and light manufacturing. The San Jacinto Valley (Hemet, San Jacinto) hosts agricultural processors and healthcare campuses. The Coachella Valley (Palm Springs through Indio) adds resort, casino, agricultural, and utility operations with unique desert electrical challenges. Banning and Beaumont anchor the San Gorgonio Pass with wind energy and growing distribution development.
Direct Source delivers NFPA 70E arc flash studies for facilities across all of Riverside County — from the western Inland Empire to the Coachella Valley desert. We serve distribution centers, food processors, wineries, resort properties, healthcare campuses, agricultural processors, water/wastewater utilities, and wind energy operations.
