“Qmerit quoted me $4,200 for a panel upgrade before they would install a charger. ChargeRight ran the NEC 220.82 math and showed I had 48 amps of spare capacity. I hired a local electrician for a $650 circuit pull. Done.”

“My house is all-gas so my panel barely has any load on it. The assessment confirmed a 40A charger circuit fit easily. My electrician was shocked the previous inspector even suggested an upgrade.”

“The assessment showed I genuinely needed an upgrade — fully loaded panel. But I walked into the electrician's office with the exact math printed out. No upsell games, no vague estimates. I negotiated $800 off because I knew exactly what was required.”

Frequently Asked Questions
Do I need a panel upgrade for an EV charger?
Most homeowners with 200A panels do NOT need a panel upgrade. A NEC 220.82 load calculation typically shows 40-60 amps of spare capacity — more than enough for a Level 2 charger. Only about 20% of homes actually require panel work. Our $12.99 assessment shows you the exact math before you commit to a $3,000-$5,000 upgrade.
How much does EV charger installation cost?
EV charger installation costs $500-$6,000 depending on what you actually need. Most homeowners only need a circuit addition ($500-$1,500). A full service upgrade runs $2,000-$5,000+. The key is knowing which level applies to your home — a $12.99 load calculation can save you thousands by proving you don't need the expensive option.
What size EV charger do I need?
A 32A charger adds ~25 miles of range per hour and is plenty for most drivers. You don't necessarily need a 48A charger — a smaller charger may let you skip a panel upgrade while still fully charging overnight. Our free calculator recommends the right size based on your driving habits and panel capacity.
Is this NEC compliant?
Yes. We use NEC 220.82 (the Optional Method), the industry-standard calculation used by licensed electricians. We also compare against NEC 220.83 and the Standard Method. Final installation should always be verified by a licensed electrician per local code requirements.
Why do you use NEC 220.82 instead of other methods?
NEC 220.82 is the industry-standard Optional Method for residential load calculations. It applies realistic demand factors (40% for loads over 10kVA) based on the fact that not all appliances run simultaneously. Other methods like the Standard Method (Part III) are more conservative, while 220.83 is specifically for adding loads to existing dwellings. We show all methods in your results for comparison.
How does the 2026 NEC affect EV charger installations?
The 2026 NEC (effective in jurisdictions adopting it) makes significant changes: lighting load reduced from 3 to 2 VA/sqft, first demand tier reduced from 10kVA to 8kVA, and critically, EV chargers must now be calculated at 100% with no demand factor allowed. We include a 2026 preview in our comparison so you can plan ahead.
What's the difference between optional and standard NEC methods?
The Optional Method (220.82) applies a blanket 40% demand factor to loads over 10kVA, resulting in lower calculated loads. The Standard Method (Part III) applies demand factors to individual load categories and produces higher, more conservative results. For most residential EV assessments, 220.82 is appropriate and widely accepted by electricians and inspectors.
What do I receive with the assessment?
A clear PDF report with your load breakdown, recommended charger size, and next-step guidance you can share with an electrician.
How do you handle my data?
We only use your inputs to generate the report. We don’t sell your data, and you can contact us to remove it at any time.
Is ChargeRight an electrical contractor or electrician service?
No. ChargeRight is an online assessment tool that runs NEC 220.82 load calculations. We provide a professional report you can share with YOUR local electrician. We don’t do installations or electrical work — we help you know what you need before you call a contractor.
How much does ChargeRight cost compared to an electrician or Qmerit?
ChargeRight costs $12.99 for a full NEC 220.82 panel assessment with AI analysis and a professional PDF report. Compare this to a $150–$300 electrician service call or a $3,000–$6,000 installation quote from a referral network like Qmerit. You could save $2,000–$5,000 by discovering you don’t need a panel upgrade.
What You Receive

- Load breakdown by category and demand factors
- Safe panel capacity and headroom summary
