Commercial Electrician EV Charging Safety

Introduction

As businesses across Los Angeles embrace electric vehicle technology, the role of a commercial electrician has become increasingly critical. EV charging infrastructure requires specialized expertise to ensure proper installation, safety compliance, and operational efficiency. Shaffer Construction, Inc., a leading general and electrical contractor serving Los Angeles and surrounding areas, understands that commercial EV charger installation is far more complex than simple plug-and-play solutions. This blog post explores the essential expertise commercial electricians bring to the table, focusing on safety protocols, code compliance, and best practices for business electrical needs in 2025.

Understanding NEC Article 625 Requirements for Commercial EV Chargers

The National Electrical Code (NEC) is the foundation of electrical safety in the United States, and Article 625 specifically governs electric vehicle charging systems. According to NFPA guidelines on NEC updates, commercial electricians must stay current with the latest code editions, which are updated every three years to enhance electrical safety standards.

Commercial electricians specializing in EV infrastructure understand several critical NEC Article 625 requirements that protect both people and equipment. First, each charging station must have a dedicated circuit separate from other building loads. This ensures the charging equipment doesn't overload existing electrical systems and reduces the risk of breaker trips during operation. Second, appropriate overcurrent protection must be sized according to manufacturer specifications and NEC ampacity tables, with cables and breakers rated for at least 125 percent of the output of continuously operated devices.

At Shaffer Construction, our commercial electricians ensure that every installation meets or exceeds these NEC standards. Proper installation of disconnecting means within sight of the charging station is also required, allowing facility managers to quickly disable the charger if maintenance or emergency situations arise. These requirements aren't optional—they're essential protections for your business and its users.

Electrical Load Planning and Infrastructure Assessment

One of the most critical services commercial electricians provide is thorough electrical load planning before EV charger installation. Many businesses underestimate the electrical demands of multiple charging stations, which can lead to costly upgrades or service expansion from local utilities. For commercial properties in Los Angeles, the electrical distribution equipment supplying branch circuits for EV charging stations must be calculated at 7.2 kVA for each space, according to current code standards.

Commercial electricians conduct detailed assessments of your existing electrical infrastructure, evaluating panel capacity, current service levels, and potential bottlenecks. This planning prevents scenarios where charging stations create demand charges that significantly increase operational costs. The Department of Energy provides guidance on charging infrastructure planning, noting that businesses must consider both immediate needs and future expansion.

Shaffer Construction's approach includes evaluating whether your facility needs Level 2 chargers (requiring 208-240V with up to 80 amps) or DC fast chargers (requiring 480V service). Each option carries different installation complexity and cost implications. Our experienced team helps Los Angeles businesses make informed decisions about charging infrastructure that balances current needs with scalability.

The reality of commercial EV charging is that demand charges can dramatically impact operating costs. A commercial facility with a 350 kW peak demand could face demand charges exceeding $7,000 annually, even before accounting for the actual energy consumption from charging vehicles. Commercial electricians evaluate peak demand scenarios and recommend demand management strategies. This might include staggered charging schedules, smart charging systems that distribute load across time periods, or utility rate programs that offer favorable pricing during off-peak hours. At Shaffer Construction, we help Los Angeles businesses optimize their charging infrastructure to minimize demand charges while maximizing convenience for vehicle users.

Safety Protocols and Personnel Protection Systems

Safety is paramount in commercial EV charging installations. Commercial electricians implement multiple layers of protection to prevent electrical hazards and shock risks. GFCI (Ground Fault Circuit Interrupter) protection is mandatory for outdoor charging stations or any installations where moisture could be present, as outlined in NEC Article 210.8. These devices detect abnormal electrical conditions and instantly interrupt power to prevent serious injury.

Personnel protection systems represent another critical safety element. Industry resources on commercial fleet charging infrastructure emphasize that chargers must include interrupting devices that block electricity flow for disconnected circuits. This prevents accidental contact with live conductors when vehicles or personnel are present.

Commercial electricians also ensure proper grounding, bonding, and cable protection. All wiring must be protected in compliance with NEC requirements, whether through conduit systems or other approved methods. At Shaffer Construction, we treat safety as a foundational requirement, not an afterthought. Our electricians verify that every installation point—from cable entry to equipment termination—meets Los Angeles building codes and exceeds industry safety standards.

Beyond passive safety devices, commercial electricians consider environmental safety during installation. They assess whether chargers are located indoors or outdoors, evaluate moisture exposure, and ensure proper ventilation if needed. They verify that electrical enclosures are properly sealed against water ingress, especially critical for outdoor installations in Los Angeles where occasional rain requires extra-duty protective measures. Cable routing must prevent trip hazards, and all equipment must be positioned to avoid direct contact with pedestrians or vehicles during normal operation.

Los Angeles-Specific Requirements and Permitting Process

Los Angeles has specific requirements for commercial EV charger installations that go beyond general NEC standards. The Los Angeles Department of Building and Safety (LADBS) requires that all commercial EV charging installations obtain electrical permits through their permitting system. For chargers and associated electrical equipment rated under 400 amps, permits can be obtained over the counter, while larger installations require more detailed plan reviews.

The installation must comply with Chapter 5 of the California Green Building Standards Code, which is adopted by reference in Los Angeles. Commercial properties must also work with the Los Angeles Department of Water and Power (LADWP) if seeking rebates or interconnection with utility programs. This involves submitting a Commercial EV Charger Customer Submittal Package and ensuring the EVSE (Electric Vehicle Supply Equipment) is permanently installed by a licensed electrical contractor.

Our comprehensive guide on preparing Los Angeles buildings for the EV charging boom provides additional context on navigating the local landscape. Shaffer Construction handles all permitting requirements, ensuring your commercial facility meets Los Angeles regulations while maintaining the highest safety and quality standards. The inspection process confirms compliance with relevant codes before your charging infrastructure goes live.

Navigating Los Angeles permitting can be complex, which is why experienced commercial electricians are invaluable. They know the specific forms required, which inspectors will review the installation, and typical timelines for each approval stage. A licensed electrical contractor must pull the electrical permit and oversee the installation, ensuring all work is performed by qualified electricians. After installation is complete, a municipal inspector verifies that the installation complies with the Los Angeles Electrical Code and California code requirements. Only after successful inspection can the system be energized and placed into service. At Shaffer Construction, our team has successfully navigated hundreds of commercial permitting processes in Los Angeles, ensuring smooth approvals and timely project completion.
