Commercial EV charger installation
A commercial charging project is a small utility project. The utility and the site plan come before the chargers.

The short answer
Commercial EV charger installation is a job for a licensed electrical contractor working with the utility: it starts with a site assessment, a load study and often a new or upgraded service, then trenching, Level 2 or DC fast chargers, accessibility, and permits. DOE advises workplaces to involve the utility and an electrical contractor early.
Level 2 or DC fast
DOE says Level 2 is the most common at workplaces, where cars park for hours. DC fast charging suits fleets and short stops but needs far more power and utility coordination.
NEC 625.40 puts EV supply equipment on its own branch circuit, and 625.41 sizes the overcurrent protection at no less than 125% of the charger’s maximum load because charging is continuous. Commercial designs often use load management to fit more ports.
Site and accessibility
Plan parking layout, trenching, lighting and signage. DOE points employers to ADA best practices for charging spaces.
Leased buildings need the owner’s consent.
Permit, time and what changes the price
Expect electrical and building permits, possibly site plans and utility applications that take weeks or months.
Price drivers: service upgrade, transformer, trenching, number of ports, network software, ADA work. No price ranges are published here until we hold enough sourced, dated quotes; see cost guides.
Choosing the contractor
Ask for commercial EV project references and the license class required for commercial work in your state. Check the license on your state board before anyone starts: how to check an electrician license.
Ask how networked billing and uptime support are handled.
Utility programs and timelines
Many utilities run make-ready programs that pay for some of the infrastructure on the utility side or up to the charger. These programs set equipment and installer requirements, so check them before choosing hardware.
Service upgrades and new transformers are often the longest step. Ask the utility for a timeline early. DOE suggests evaluating goals and needs first so the project fits how people actually park.

Primary-source research and fact checking
We read the model code, the federal safety notice, the municipal fee sheet or the utility tariff ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. HyreElectrical does not perform, supervise or warrant electrical work. Authorship is organizational: this desk, not a named persona.

How this desk works
- Primary sources only. Code statements come from NFPA 70 as the model code. Safety statements come from CPSC. Permit fees come from the city or county fee sheet. Utility charges come from the filed tariff. We do not cite a blog that cites a source; we open the source.
- Our contractor store is five states, and 74% of it is Florida. Any figure built on that store is titled to those states and names the concentration in the first screen. It is not a national sample of electricians.
- Load calculations on this site are a published simplification in the shape of NEC 220.82 — first 10 kVA at 100%, remainder at 40%, HVAC at 100%, EVSE at 125%. They are labeled as not a stamped calculation. A licensed electrician using the adopted edition does that work.
- No national price for a panel upgrade is shipped. Labor rates, the adopted code edition, whether the utility is involved, and the state of the existing wiring move the invoice too far for a roundup to help. The cost pages publish named permit fees and the variables that move the price instead.
- We do not perform electrical work, and we take no payment for placement, ranking or a favorable mention. Nobody buys a position on this site.
Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
Sources & retrieval dates
HyreElectrical is a publisher. It does not perform, supervise, inspect or warrant electrical work, holds no electrical license, and matching is still being built, so an inquiry is not a service call.
This page is general information, not a diagnosis or a quote. Code rules vary by the NEC edition your state or city adopted and its local amendments.
