Electric vehicle adoption across the Phoenix metro area is accelerating at a pace that business owners and property managers cannot afford to ignore. Customers arrive in electric vehicles expecting charging to be available. Employees factor workplace EV charging into their employment decisions. And commercial properties without charging infrastructure are increasingly at a disadvantage in a market where EV readiness is becoming a standard expectation rather than a premium amenity.
This commercial EV charger installation guide is designed to give business owners, property managers, and commercial developers a clear, practical understanding of what commercial EV charger installation involves from start to finish. At Just Right Electric PHX, we handle commercial EV charging projects throughout the Valley and have put together this guide to help businesses make informed decisions about this important infrastructure investment.
Step One: Assess Your Property and Electrical Infrastructure
Every commercial EV charger installation begins with a thorough assessment of the property and its existing electrical infrastructure. This step determines what is feasible, what upgrades may be required, and what the full scope of the installation project will involve.
The electrical panel or service entrance is the starting point. Commercial EV chargers, particularly Level 2 units running at 240 volts, place significant additional load on the building’s electrical system. Just Right Electric PHX evaluates available panel capacity to determine whether the existing service can support the planned number of chargers or whether a panel upgrade or service entrance upgrade is required before installation can proceed.
The distance between the electrical service and the planned charging locations is equally important. Longer circuit runs require larger wire gauge to maintain safe voltage levels at the charger, and underground conduit installation may be necessary to reach parking areas that are distant from the building’s main electrical service. Understanding this at the assessment stage prevents surprises during installation.
Step Two: Choose the Right Charger Type
Commercial EV charger selection depends on your property type, your users, and how they will use the charging facility.
Level 2 chargers operating on 240 volt dedicated circuits are the most common choice for commercial installations. They add 20 to 30 miles of range per hour, which is ideal for users who park for extended periods such as office employees, hotel guests, restaurant diners, and retail shoppers. Level 2 chargers are cost effective to install, straightforward to operate, and compatible with virtually every electric vehicle on the market.
Level 3 DC fast chargers are appropriate for locations where users need rapid charging in a short time. Highway corridor locations, fleet operations, and high traffic retail destinations are the primary use cases. Level 3 installation is significantly more complex and expensive than Level 2, requiring three phase electrical service, larger infrastructure, and more extensive permitting.
Just Right Electric PHX helps businesses select the right charger type for their specific use case and user base, ensuring the investment delivers genuine value rather than over or under specifying for the situation.
Step Three: Plan for Scalability
One of the most important decisions in a commercial EV charger installation is planning for future expansion at the time of the initial installation. EV adoption is growing rapidly, and a property that installs two chargers today may need six within a few years as demand increases.
Just Right Electric PHX designs commercial charging installations with scalability built in. That means sizing conduit runs and electrical infrastructure to accommodate additional chargers without requiring extensive rework when expansion becomes necessary. The cost difference between planning for future capacity at installation time and retrofitting for it later is significant. Building in that flexibility from the start is always the more cost effective approach.
Step Four: Permitting and Utility Coordination
Commercial EV charger installation involves permitting requirements that vary by jurisdiction but are non-negotiable in every case. Just Right Electric PHX manages the complete permitting process for every commercial EV installation project, pulling the required permits, preparing documentation, and coordinating with local inspectors to ensure every aspect of the installation meets applicable codes.
Utility coordination is a dimension of commercial EV installation that is often overlooked until it becomes an obstacle. The additional electrical load of multiple commercial EV chargers may require coordination with the utility provider, particularly for properties that need a service upgrade to support the increased demand. Just Right Electric PHX manages this coordination as part of every commercial project, ensuring utility side requirements align with on site electrical work before installation begins.
Step Five: Installation and Civil Work
The physical installation of commercial EV chargers involves electrical work and in many cases civil work that must be carefully coordinated.
Electrical work includes circuit installation from the panel to each charging location, proper wire sizing for the circuit length and charger amperage, weatherproof enclosures for all outdoor electrical connections, and GFCI protection where required by code. Just Right Electric PHX handles all electrical components of every commercial installation to current NEC and OSHA standards.
Civil work typically includes underground conduit installation between the building and parking area charging locations, concrete pad preparation for charger mounting, and trenching for conduit pathways. Just Right Electric PHX coordinates all aspects of the installation so the electrical and civil components proceed in the right sequence without delays or conflicts.
Step Six: Testing and Commissioning
Every commercial EV charger installation concludes with comprehensive testing and commissioning before the system is considered ready for use. Just Right Electric PHX tests every charger unit, verifies correct voltage and current delivery, confirms GFCI protection is functioning correctly, and ensures all smart features and network connectivity are operating as expected.
We provide clear documentation of the completed installation and walk property owners and managers through the operation of the system before handing it over. Every business we work with leaves the commissioning process with complete confidence in the charging infrastructure that has been installed.
