Load shedding is an automatic management feature on certain generator and transfer switch combinations that turns off lower-priority circuits when total home demand approaches the generator output limit, then restores those circuits when demand falls back within range. It is the mechanism that allows a 14kW or 16kW generator to serve a home that would otherwise require a 22kW unit for simultaneous whole-house coverage.
A typical load shedding configuration prioritizes life-safety loads (sump pump, well pump, furnace blower) and comfort loads (refrigerator, lighting) while shedding controllable loads (electric water heater, EV charger, electric dryer) when the AC compressor starts and creates a demand spike. The shedding and restoration happen automatically without any action from the homeowner.
Whether you need load shedding depends on your generator sizing approach. A properly sized 22kW or larger whole-house Generac generator handles the full home panel load simultaneously without any shedding, providing the simplest and most transparent user experience during an outage. Load shedding is the right tool when the budget or property constraints favor a smaller generator, not when the goal is whole-house coverage without compromise.
