Load management is traffic control for electrical demand
A standby generator has a finite output. Some homes contain large loads—air conditioning, electric water heating, pumps, cooking equipment, dryers, pool equipment, or other motors—that do not need to start at the same instant. A load-management system can delay, shed, or lock out selected loads according to the equipment’s design so demand stays within what the generator and system can support.
Generac describes its Load Manager as a device that can shed connected loads when it detects overload conditions and restore them according to priority. Champion’s 201222 aXis system says its whole-house ATS can manage high-demand appliances using separate aXis Load Management Modules. Cummins describes QuietConnect load-management kits as preventing overload by turning equipment on or off based on household demand.
Not a DIY wiring guide
Load managers, transfer switches, generator connections, service equipment, and large appliance circuits involve hazardous electrical work. This page explains decision concepts only. Use the exact manufacturer manuals and qualified electrical professionals for design and installation.A simple priority sequence

Generator + approved transfer equipment
Available capacity is finite and depends on the exact model, fuel, load, and system.
Priority group
Loads that should recover first
Example categories might include refrigeration, controls, selected lighting, or a critical pump—only if the actual design supports them.
Managed large loads
HVAC / water heat / other high demand
The system may delay, shed, lock out, or later restore selected loads according to its rules and priorities.
Manufacturer examples show why the exact system matters
Generac Load Manager / former Smart Management Module
Generac’s current support material says its Load Manager can manage large loads by monitoring generator frequency and shedding a connected appliance when overload conditions are detected. It describes priority settings from 1 through 8 and a lockout option. Generac also says systems can use up to eight individual Load Managers, with additional integrated SACM-managed loads in supported configurations. Those limits and behaviors are product-specific and should be confirmed for the exact controller, ATS, and generation.
Champion aXis
Champion’s model 201222 is sold as a 22 kW LP / 19.8 kW natural-gas system with a 200 A aXis ATS. The manufacturer says the ATS can manage high-demand appliances using aXis Load Management Modules model 100868, sold separately. That means a quote should state whether modules are included, how many, and which appliances they control rather than simply saying “whole house.”
Cummins QuietConnect
Cummins’ QuietConnect overview describes load-management kits that work with its intelligent load-management approach to turn equipment on or off based on household demand. The exact available kit, transfer equipment, priority behavior, and generator compatibility should be confirmed for the selected system rather than inferred across the whole brand.
Load management does not create extra kilowatts
Sequencing can make a finite generator serve a broader set of loads over time, but it cannot make every large load run simultaneously if the generator, fuel supply, transfer equipment, and wiring are not designed for that demand. It also cannot replace motor-start analysis. A large compressor or pump may still have a brief starting requirement that the designer must account for.
Do not use load management as an excuse to choose an arbitrary smaller generator. The useful question is whether a qualified designer can document a system in which the selected generator, fuel-specific rating, starting requirements, priority strategy, and transfer equipment work together for the loads you actually want backed up.
Questions to ask before accepting a load-management design
- Which exact loads are managed, and which remain unmanaged?
- What are the priority settings, lockouts, or recovery rules for each managed load?
- Which loads may never operate together on generator power?
- What motor-start assumptions were used for HVAC, wells, pumps, or other large motors?
- Which generator fuel rating and transfer-switch configuration were used in the design?
- Which load-management modules/controllers are included in the quote, with exact model numbers and quantities?
- How is the system tested during commissioning to confirm the intended priority and recovery behavior?
- What happens if a managed module fails, loses communication where applicable, or is manually locked out?
Record those answers in the quote checklist so the load-management plan becomes part of the written project scope.
