Briggs and Stratton Dual 200 Amp Split 400 Amp Automatic Transfer Switch
Service Entrance Rated, NEMA 3R, UL 1008 Listed
If your home has 400 amp service split across two 200 amp breaker panels, a standard transfer switch setup can get complicated fast. The Briggs and Stratton Dual 200A Split 400A Automatic Transfer Switch (ATS) is built specifically for that situation.
It is a 2 in 1 ATS system in a single enclosure that controls and supplies both 200A panels during an outage. It automatically detects a utility failure, starts the standby generator, and transfers power to keep your home running. When the utility comes back, it switches you back automatically.
This is the clean, code-friendly solution for split 400A homes that want true automatic backup without cobbling together two separate switches.
Built for split 400A services (two 200A panels)
Many larger homes have what is commonly called “split 400 amp service,” where the incoming utility feed is divided between two main distribution panels, each rated at 200 amps. You still have 400A service available, but it is split across two panels.
This transfer switch is designed around that exact layout:
- Dual 200A transfer switching in one enclosure
- Powers both panels during an outage
- Replaces the need for two separate 200A transfer switches
- Smaller footprint and simpler installation path than running two standalone ATS units
In short, it is the right switch for the right type of service.
Automatic operation that keeps the power on
A Briggs and Stratton transfer switch provides the “brain” your standby generator needs.
What it does automatically:
- Senses loss of utility power
- Sends the start signal to your generator
- Transfers your home from utility power to generator power
- Monitors utility restoration
- Transfers your loads back to the utility once power is stable
- Signals the generator to shut down
That means no dragging cords, no manual switching, and no guessing if the power is safe to transfer back.
Service Entrance Rated with Disconnect
This model is Service Entrance Rated with an integrated disconnect, giving installers flexibility when working with different panel configurations.
It is designed to support installations where the home has:
- 200A panels with a main breaker
- 200A panels without a main breaker
This is a big deal in split 400A setups, because service entrance rating and disconnect requirements can affect how the system gets permitted and wired.
Outdoor ready, code-friendly enclosure
- NEMA 3R enclosure for indoor or outdoor use
- UL 1008 listed for automatic transfer switches
- Built for real world weather exposure and long-term reliability
For homeowners, that translates to confidence that it is built for the job and recognized by inspectors.
