Generac 100 Amp Legacy Automatic Generator Transfer Switch, SE Rated | Non Integrated Surge Protection Device, Service Entrance Rated, NEMA 3R Outdoor Enclosure, Standard Smart Switch A/C Module

AUTOMATIC WHOLE-HOME BACKUP ACTIVATES THE MOMENT UTILITY POWER FAILS: senses an outage, starts your compatible Generac generator, and transfers your entire panel automatically, unlike a manual interlock kit requiring hands-on action every time
OPEN TRANSITION SWITCHING PREVENTS BACKFEED INTO THE UTILITY GRID: mechanically isolates utility and generator power so both can never connect at once, protecting line workers and your wiring while your panel switches sources safely
100 AMP SERVICE RATING SUPPORTS YOUR FULL 120V AND 240V PANEL: handles up to 24000 watts across your entire home, including 240V loads like well pumps and dryers, so you back up the whole panel instead of a limited set of circuits
BUILT IN SMART AC MODULE MANAGES UP TO 4 HVAC LOADS AUTOMATICALLY: sequences up to four air conditioning or heating loads without extra hardware, and optional Smart Management Modules add circuit control as your needs grow
NEMA 3R ALUMINUM ENCLOSURE WITHSTANDS OUTDOOR WEATHER EXPOSURE: powder-coated aluminum housing resists corrosion and moisture for reliable performance whether mounted outdoors or in a garage near your main panel
DESIGNED FOR GENERAC STANDBY GENERATORS WITH EVOLUTION OR NEXUS CONTROLS: this switch is engineered specifically for Generac home standby generators, not portable units from other brands, so confirm your generator's controller before ordering
SERVICE ENTRANCE RATING MEANS A LICENSED ELECTRICIAN MUST INSTALL IT: functions as your main service disconnect and ties directly into utility service, so local code requires a licensed electrician and permit for this installation

Generac 7006 Load Manager, 100 Amp, Efficient Wire-Free Technology, Customizable Load Prioritization, LED Status Display, Gray

BROAD GENERATOR COMPATIBILITY: Works with any single-phase standby generator that produces standard 60 Hz AC output, including Generac air-cooled and liquid-cooled models — single-phase 240V only, not for three-phase systems
SCALE UP TO 8 MODULES PER SYSTEM: Install up to eight 100A Load Managers on a single generator system to manage multiple large appliances independently, with each module requiring a unique priority number
WIRE-FREE FREQUENCY SENSING TECHNOLOGY: No control wires to the transfer switch are needed; the module monitors generator output frequency autonomously and sheds loads the moment Hz drops below threshold
NEMA 3R RATED FOR INDOOR OR OUTDOOR MOUNTING: Enclosure withstands rain, sleet, and ice formation across an operating range of -22°F to 122°F, sized at 7.0"H x 11.4"W x 5.3"D for flexible placement
8-LEVEL PRIORITY DIAL FOR CUSTOMIZED LOAD RECOVERY: Assign each module a unique priority 1–8; lower numbers recover power first after a shed event, with each step adding a 15-second staggered delay to prevent re-overload
GENERATOR LOCKOUT MODE BLOCKS NON-ESSENTIAL LOADS: Set any module to lockout to permanently prevent that appliance from drawing generator power during an outage, while still allowing it to run normally on utility power
EXTERNAL LED STATUS DISPLAY WITH 5 CODED STATES: Diagnose system status without opening the enclosure; solid green means load connected, 1-second flash means startup delay, and 3-second flash means 30-minute overload lockout is active
