It needs to show how the panel is actually laid out after the charger is added — not just a sticker that says “lights” and “kitchen.” For an EV permit, that usually means a revised schedule: each branch-circuit breaker and its size, a description of the load or room it serves, the two-pole EV breaker with its rating and the EVSE it feeds, the main-breaker or service size, and enough information that the inspector can match the paper to the panel. Public checklists such as the City of Orlando EV charging station permit checklist ask for that revised schedule together with the load calculation.
If the existing directory is wrong, the electrician will redo it, which is a safety improvement on its own. The schedule is not a substitute for the load calculation, and the calculation is not a substitute for the schedule: one is about capacity, the other is about what is physically in the can. Tandem positions, spare spaces, and a subpanel feeder should be obvious on the sheet if they exist.
You can help by photographing the open door (not the dead front) and the existing directory before the site visit. The calculator will not generate a permit schedule; the electrician’s drawing will.
This is not a permit calculation, a utility approval, or a substitute for a licensed electrician, HVAC contractor, or the authority having jurisdiction. Panel Headroom is an independent educational site. It is not a utility, a certification body, or a contractor. Electrical and generator work that is done incorrectly can cause fire, shock, or carbon monoxide poisoning. Use the adopted electrical code and manufacturer instructions; pull permits where required.
