Installing EV charger without checking if panel can handle it. Results in tripped breakers, inability to use other appliances while charging, or fire risk. Always run a load calculation first.
Using 10 AWG wire on 50A circuit or aluminum wire. Undersized wire overheats and creates fire hazard. Always match wire gauge to breaker amperage per NEC table 310.16.
Installing without permit to save money. If there's ever an electrical fire, insurance may deny claim. Reselling home requires disclosure. Permits cost $50-200 but protect you legally.
Installing charger too far from parking spot, in area prone to vehicle damage, or where cable becomes tripping hazard. Plan cable routing carefully and protect charger from damage.
Permit check
A hardwired charger or new 240V circuit is permitted electrical work.
Inspections: Final (some areas add a rough-in)
Code changes
Model codes update every three years, and the parts that move this sheet are EV circuit sizing, load calculations and energy management systems. Leave an email and we will tell you when we update it for a new code cycle.
Local code notes for your county
Cities and counties amend the NEC, and the amendments are what inspectors fail people on. Tell us where the job is and your project gets the notes that apply there.
Ask about your situation. Posting needs a free account, and your question carries over so you get an answer with your project in view. Questions we hear often get answered on this sheet.
