The Department of Energy’s charging guide puts it plainly: electricians can tell homeowners whether their home has adequate electrical capacity for vehicle charging. The same question sits behind a standby generator, a heat pump and the new circuits in a remodel. That makes the panel the hub of an electrical shop’s planned work, and it changes how those jobs should be sold.
The code sets the scope. The National Electrical Code treats EV charging as a continuous load, and Article 625 holds most of the rules for charging equipment; the DOE adds that permits may be required. NFPA issued the 2026 edition on August 20, 2025. As of August 3, 2026 it was in effect in six states, with the 2023 edition in 20, the 2020 edition in 15, the 2017 edition in three and the 2008 edition in two. Texas has enforced the 2023 NEC since September 1, 2023, and California’s 2025 Electrical Code, based on the same 2023 edition, took effect January 1, 2026. A charger or panel page that names the edition your inspector enforces reads like a local shop wrote it. One that quotes a national rule does not.
The credits are gone. The 25C credit covered panelboards of 200 amps or more and ended for property placed in service after December 31, 2025. The 30C credit for home chargers ended for property placed in service after June 30, 2026, and it only ever applied in eligible low-income or non-urban census tracts. Neither belongs in an ad today.
Some rebates are not. The DOE’s Home Energy Rebates list electric wiring and load service center upgrades among the costs they cover, and they are available in select states. Where your state runs them, a panel page can say so, naming the program. Where it does not, saying nothing beats implying something.
California adds a second credential. A C-10 contractor’s license covers the business, and state law requires the people doing electrical work for C-10 contractors to be certified electricians. A shop that says both, with the license number in every ad as the state requires, answers the question a careful homeowner is already asking.
The quote is the sale. One lead-site estimate puts a panel upgrade at four to eight hours of work, but the decision takes longer: a load check, a quote, a permit and, in our experience, often a utility appointment. That is why we track panel, charger and generator leads apart from service calls, follow up on every open quote, and judge those campaigns on installs rather than on calls.
