Benefits

Scalable, lightning-hardened design

We engineer layered surge protection architectures optimized for Altadena’s elevated lightning exposure. Type 1 or Type 2 UL 1449 4th Edition SPDs at the service entrance, coordinated Type 3 devices at sensitive subpanels, and point-of-use protection for critical equipment provide comprehensive defense. We specify devices by system voltage, available fault current (SCCR), maximum continuous overvoltage (MCOV), surge current capacity (often 160–320 kA for foothill environments), and IEEE C62.41 surge environment categories. Integration options include dry-contact monitoring for building management systems, networked surge counters, remote status indicators, and alarm integration—delivering measurable, documented protection that scales as your facility evolves and meets insurance requirements for high-lightning areas.

Permits and compliance

Shaffer Construction manages all permitting, documentation, and inspection coordination with LA County Building and Safety. Our installations comply with the 2023 California Electrical Code (based on NEC 2020), including Article 242 for surge protective devices, Article 250 for grounding and bonding, and relevant NFPA 70 labeling and documentation requirements. We provide complete submittal packages with single-line diagrams, panel schedules, SPD specifications, grounding enhancement plans, and installation methods that meet inspector expectations. For facilities with emergency systems or life-safety equipment, we ensure protection integration complies with Article 700 and Article 701 requirements. We coordinate SCE meter shutdowns when required and maintain clear communication with property managers, tenants, and business owners throughout the approval process.

Commercial-grade, lightning-rated materials

We exclusively install commercial-rated, UL 1449-listed surge protective devices from industry-leading manufacturers (Eaton, Siemens, Schneider Electric, ASCO Power Technologies, Mersen) with proven performance in high-lightning environments. Installations emphasize ultra-short lead lengths (typically under 12 inches), appropriately sized copper conductors, direct bus connections, and high-quality terminations torqued to manufacturer specifications using calibrated tools. All grounding enhancements utilize listed copper-clad steel ground rods (often multiple rods for foothill properties), exothermic welds or compression connectors, proper bonding jumpers, and corrosion-resistant hardware. We apply comprehensive labeling per NEC Article 110 and 242 requirements and provide detailed as-built documentation with ground resistance test data, thermal imaging results, and device specifications.

Comprehensive facility assessment

Every Altadena commercial project begins with a thorough electrical system evaluation. We review main service capacity and configuration, assess panel conditions and available space, measure grounding electrode system integrity (critical in foothill soil conditions), map subpanel distribution, and inventory sensitive loads—POS systems, servers, HVAC controls, refrigeration, security, specialized equipment. For multi-tenant facilities, we evaluate shared services and coordinate protection strategies. Our assessments identify code deficiencies, inadequate grounding, undersized services, lightning vulnerability, and opportunities for protection enhancement. For fire-rebuilt properties, we review as-built plans and coordinate with general contractors. The result is a tailored protection plan that addresses your facility’s specific lightning exposure profile, operational requirements, budget constraints, and future expansion needs while ensuring full code compliance.

Frequently Asked Questions

Will surge protection installation disrupt our business operations?+

We plan installations to minimize disruption, scheduling work during early mornings, evenings, weekends, or slower business periods. Most service-entrance SPD installations are completed in 3–5 hours. If a brief power shutdown is required, we coordinate timing with your operations, provide advance notice to staff and customers, and ensure life-safety systems remain functional throughout. For businesses that cannot tolerate downtime, we can often phase the work across multiple short visits or coordinate with SCE for after-hours meter access.

Why is lightning protection more critical for Altadena businesses than valley or coastal locations?+

Altadena’s foothill location creates significantly elevated lightning exposure—typically 4–6× higher than valley or coastal areas. Summer monsoon storms and winter weather systems generate frequent lightning that strikes elevated facilities and induces voltage spikes through utility lines serving the entire community. Even facilities that aren’t directly struck are vulnerable to surges from nearby events traveling through power, data, and telecom lines. For businesses with expensive equipment, critical refrigeration, or sensitive electronics, the modest investment in professional SPDs provides essential protection that valley/coastal facilities may not require to the same degree.

Are permits required for commercial surge protection in Altadena?+

Yes. LA County Building and Safety requires an electrical permit for SPD installations at service equipment or distribution panels. We handle the entire permit process—application preparation, submittal, plan review coordination, and inspection scheduling. Most surge protection projects receive approval within 1–3 weeks. We provide all required documentation including single-line diagrams, equipment specifications, and installation methods that meet inspector expectations. For multi-tenant buildings, we also coordinate with property management and provide required tenant notifications.

Can you protect our restaurant’s refrigeration and kitchen equipment?+

Yes. Restaurant equipment—walk-in coolers, reach-in refrigerators, ice machines, commercial ovens, hood controls, POS systems—is highly vulnerable to surge damage. We design protection strategies that include service-entrance SPDs, dedicated subpanel protection for kitchen circuits, and sometimes point-of-use devices for especially sensitive or critical equipment. Properly coordinated protection reduces compressor failures, extends equipment life, prevents food loss from refrigeration shutdowns, and minimizes expensive emergency service calls.
