your home's electrical system and existing LP or natural gas fuel supply, so you can be protected the next time the
lights go out.

Hands-Free Automatic Operation
When the power goes out, this generator eliminates the trouble of dealing with a fuse box in a dark basement or going
outside in a storm to start a portable generator. After all LP or natural gas and electrical connections are completed, the
Generac 5872 is ready to run 24/7 and requires absolutely no manual operation, no fueling, and no extension cords. The
generator responds within seconds of power outages, so inconveniences like heat or air conditioning loss and burst
pipes or spoiled food are quickly avoided.
Initial setup is easy. The generator arrives pre-wired and equipped with the necessary installation gear: a 14-circuit
transfer switch (NEMA 1, indoor-rated only), pre-wired conduits, an outdoor connection box, a flexible fuel line pigtail,
and a composite mounting pad. (Additional items and tools may be needed to complete the installation to meet local
codes. Consult a licensed professional for further details.)
The unit can be programmed to perform a weekly exercise at the time of your choice, so it will be ready for continuous
and reliable operation on a moment's notice. For your convenience, it also offers a two-line LCD digital controller, an at
a glance indicator light and system status LED, plus an easy-to-access external main circuit breaker.
Superior Technology for Secure Output, Quiet Operation, and Durability
Thanks to Generac's exclusive True Power Technology, this generator provides clean, continuous power, so sensitive
electronics and microchip appliances like laptops and HVAC equipment can be operated without the worry that
unexpected power surges bring. The ultra-quiet design means that noise levels during self-tests are 1/3 quieter than
portable generators, so your daily routine is unaffected.
The generator's corrosion-resistant, galvanized steel enclosure is protected by Generac's proprietary RhinoCoat
system--a unique process that binds the paint to the metal surface for a long-lasting, durable finish. This allows the

3. generator to sit outdoors and withstand harsh weather conditions without developing an unsightly appearance.
Like all Generac generators, this model is UL (Underwriters Laboratories) listed for safety.
Rugged, Worry-Free Design
The generator features the 992cc Generac OHVI® Engine, an exclusive air-cooled generator engine with a
high-performance design that can accommodate large electrical loads. The engine optimizes power to respond swiftly to
changing conditions. To add to your peace of mind, the engine requires routine maintenance only once every two years,
or after 200 hours of use.
This Generac generator meets CARB requirements. It requires a Group 26R 12-volt minimum 525 CCA battery (sold
separately).
