🟢check_panel_capacity(main_breaker_amps, charger_amps, square_footage, appliances)
Check whether a home's electrical panel has capacity for an EV charger. Use when a user asks if their panel or breaker box can handle an EV charger, or whether they need a panel upgrade or load management. Returns a verdict (fits / tight / does-not-fit), amps, and a plain-language explanation.

}🟢recommend_charger_setup(charger_amps, wire_material, ambient_temp_c, run_length_ft)
Recommend breaker size, wire gauge, conduit, and ground wire for a home EV charger circuit. Use when a user asks what wire size, breaker, or circuit their charger needs. Returns wire gauge, breaker amps, EGC size, and a plain-language explanation with NEC citations.

Check whether a cable run length causes excessive voltage drop for an EV charger circuit. Use when a user asks about long garage/driveway runs, voltage drop, upsizing wire for distance. Returns pass/fail at 3%.
