Check bills, meter data, panel photos, and charger plans before you buy gear or promise an install date.
Ampscale gives a conservative headroom range, shows whether scheduled or capped charging is needed, and lists the exact proof an electrician, engineer, utility, or permit reviewer will ask for.
Each added proof point tightens the range and makes the package easier to review.
Find the real peak and the months that set it.
Confirm service size, breaker rating, voltage, phase, and open questions.
Compare uncontrolled charging with a managed limit and failure behavior.
Enough practical headroom appears available with conservative margin.
The permit package needs the cap, sequence of operations, labels, and logs.
Customer-side headroom is not the same as transformer or feeder capacity.
Send the site, project, and best evidence you have. We will return the headroom range, confidence grade, missing proof, and likely approval path.
