For Easy Generac Generators Installation: Load-Shed ATS 200A

200-Amp Load-Shedding Switch

Generac's load-shedding 200-amp switch can be utilized with 1-phase Guardian and QuietSource standby generators, both air and liquid-cooled models, from 8 kW to 48 kW. Has 16-circuit priority-load center built in. Here is how load shedding works: priority circuits are selected based on generator's capacity - up to total of 16. These priority circuits are operated continuously; whenever excess generator capacity exists, unprotected (low-priority) circuits will be activated one by one until capacity has been exhausted. As the generator requires more power for its priority load, unprotected circuits are deactivated in reverse order, as many as necessary, until the priority circuits are fully powered once again. This load-shedding switch is the best means of maximizing a generator's output in single-phase application. Estimated that load-shedding technology can have generator performing like model 20% to 30% larger that utilizes a standard transfer switch.

  • Important: See the shipping tab for information regarding our liftgate option, and residential versus commercial deliveries. At present, because T-Rex is shipping Generac products direct from the company's Wisconsin-based factory, any
  • residential delivery weighing in excess of 80 lbs will require the $75.00 liftgate shipping option. Shipments to commercial addresses (non-residences) remain exempt from these charges unless specified by customer.
