Load shedding
Load shedding is automatically dropping lower-priority circuits when generator demand approaches capacity — letting a smaller standby generator protect a whole panel by making sure the air conditioner and dryer never run at the same time.
Standby systems implement it with smart management modules on selected circuits (typically the AC condenser, water heater, dryer, or EV charger): when frequency or load signals stress, the module drops its circuit and restores it when headroom returns.
This is why a 14 kW generator can legitimately back a 200 A panel: the load calculation counts managed loads differently. It is also the honest answer to “can I run everything?” — yes, just not simultaneously.
