Most EV installs don’t need upgrades
Master electrician Jason Walls says NEC 220.82 load calculations show roughly 70% of EV owners don’t need expensive panel upgrades — he shared a real case that saved a homeowner $6,200 and flagged AI as a quick verification tool. Walls also launched ChargeRight, a $12.99 AI‑powered load‑calc tool built with Claude AI to streamline that check. (x.com)
ChargeRight’s homepage lists “860,000+ homeowners” reached and shows a 4.8★ rating with 127 verified reviews. (evchargeright.com) (evchargeright.com) Founder Jason Walls is identified on the site as an IBEW Local 369 master electrician with 10,000+ field hours and union apprenticeship credentials. (evchargeright.com) (evchargeright.com / evchargeright.com/about) ChargeRight’s technical explainer walks through NEC 220.82’s Optional Method and specifies the demand‑factor math: the first 10,000 VA at 100% and the remainder at 40%, with a worked example showing a 25,000 VA connected load calculating down to about 16,000 VA. (evchargeright.com) The product flow described on the site requires a homeowner panel photo for automated analysis and returns a NEC 220.82‑based PDF report that the company says shows both “no upgrade needed” and “upgrade confirmed” verdicts. (evchargeright.com) (evchargeright.com) Multiple news and aggregation pieces report wider visibility after entrepreneur Mark Cuban reshared Walls’ posts, bringing broader media attention to the tool and its claims. (msn.com) (msn.com / ainvest.com) Site case examples include homeowner testimonials citing avoided panel upgrades with concrete savings amounts (sample figures shown: $3,550 and $2,800 avoided) and at least one documented instance where the assessment confirmed an upgrade was legitimately required. (evchargeright.com) (evchargeright.com) ChargeRight’s pages also point users to the Department of Energy panel calculator for comparison and state that their NEC 220.82‑based analysis is tuned for EV‑specific scenarios rather than the DOE’s general worksheet.
