EV Charger Installation Certification Test

The EV Charger Installation Certification Test is a free intermediate-level, 20-minute skill test from Science of Apps. It tests EV charger installation knowledge — EV charging fundamentals and connectors, NEC Article 625 and electrical requirements, load calculations and site assessment, and installation, commissioning and networked charging — written to NFPA 70 (NEC) Article 625, US DOE Alternative Fuels Data Center guidance, EVITP training topics and the OCPP standard for 2026. Always follow your local adopted code and permit rules. Score 70% or more on its 20 questions to earn a verifiable EV Charger Installation certificate (SOA-EC). Every question is based on published standards and research — including Developing infrastructure to charge electric vehicles (US DOE Alternative Fuels Data Center), NFPA 70 (NEC) Article 625: Electric Vehicle Power Transfer System (National Fire Protection Association), Electric Vehicle Infrastructure Training Program (EVITP) (EVITP) — and each answer is explained with its source.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: Developing infrastructure to charge electric vehicles (US DOE Alternative Fuels Data Center); NFPA 70 (NEC) Article 625: Electric Vehicle Power Transfer System (National Fire Protection Association); Electric Vehicle Infrastructure Training Program (EVITP) (EVITP); ADA Accessibility Standards (US Access Board); NFPA 70E: Electrical safety in the workplace (NFPA); Open Charge Point Protocol (OCPP) (Open Charge Alliance). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: EV Charging Fundamentals (Charging levels, Connectors and Vehicles and batteries); NEC Article 625 and Electrical Requirements (Continuous loads, Protection and Disconnects); Load Calculations and Site Assessment (Service capacity, Site survey and Planning); Installation, Commissioning and Networked Charging (Installation practice, Testing and commissioning and Networking). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

Electrician, EV charger installer, Electrical contractor, Facilities manager and Electrical apprentice. It suits anyone who wants a quick, verifiable way to show EV Charger Installation knowledge in 2026 and 2027, from students and career switchers to experienced professionals.

Installation must be done by a qualified (usually licensed) electrician under local rules. Programmes such as EVITP certification are required for some publicly funded projects in the US, including NEVI-funded chargers.

EV charging is a continuous load, so the branch circuit must be rated at 125% of the charger's maximum current. A 48 A charger needs at least a 60 A circuit.
