Prepping your home for backup power? This 200 Amp manual transfer switch lets you safely connect a generator to your home's electrical panel. It's rated for 120/240V and can handle generators up to 48,000 watts – enough for most large homes or small businesses. It's a double-throw, 2-pole switch with a neutral connection. The enclosure is NEMA 3R rated, so it can be installed indoors or outdoors (resists rain and dust). Features include clear ON/OFF/ON markings, a side handle lock to prevent accidental switching, AL-CU terminals that accept a wide range of wire sizes (14 AWG to 250 MCM), and arc arrestors for safety. Installation requires a qualified electrician, but the wiring is straightforward with the provided diagram. Flip the handle to switch from utility power to generator power and keep your essentials running during an outage.
