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.


Key specs

  • Amperage: 2 x 200A (dual 200A switching for split 400A service)
  • Phase: Single phase
  • Voltage: 120/240V
  • Frequency: 60 Hz
  • Poles: 2 pole
  • Enclosure: NEMA 3R indoor/outdoor
  • Listing: UL 1008
  • Dimensions (L x W x H): 34 x 24 x 7 in

Important requirement

This 2 in 1 transfer switch must be bundled with a Briggs and Stratton standby generator. It is designed as part of the Briggs and Stratton standby ecosystem so the controls and start/transfer behavior work correctly together.


Why this is the right choice for split 400A homes

  • Purpose-built for homes with two 200A distribution panels
  • One enclosure instead of two separate ATS boxes
  • Automatic start and transfer during outages
  • Service Entrance Rated disconnect flexibility
  • Weather rated NEMA 3R enclosure for outdoor installs
  • UL 1008 listed for code compliance and peace of mind

Excellent value for an automatic watch, keeps VERY good time.
Color: Grey, Color: Grey
I've only had the watch for a day but wanted to leave a quick review on it to share a couple of notes. So far it keeps VERY good time, better than any of the automatics I own (including a Rolex Submariner, Tag Heuer Aquaracer, Tag Heuer Formula One, and several other sub $1k watches). I set it to an atomic time app on my phone yesterday and 24 hours later it's still SPOT on - hasn't gained/lost even a 1/10 of a second. I was shocked to see it's kept PERFECT time for the last day, I'm really blown away so far. I've worn it the entire time, we'll see how well it keeps time while being stored in a winder. This picture shown is the watch with a 22mm leather band on it, fit's without any issues (just need to squeeze in the leather a tad). I doubt it would work with a 22mm metal bracelet, but leather works great. Just FYI since the 21mm lug width is kind of odd. The face isn't quite a lustrious as the images make it look, but it's still a great-looking watch. For a sub $1000 automatic you can't go wrong, this is a fantastic watch at a great price. It'll be my daily driver for some time I'm sure. If I have any issues in the future I'll update the review.

It looks really cool and striking.

Really cool and beautiful watch. Although my specific unit runs 5 seconds fast every day—at first it’s annoying, but eventually you stop caring. 🤣

A Beautiful Timepiece at an Awesome Price!!
Color: Grey, Color: Grey
I have lusted after this watch for four months. I first tried on a similar model (stainless steel band with a green face) in a local jewelry shop (Spitz Jewlers, Walnut Creek, CA, USA). It was "love at first sight," even if I didn't love the white lines on the face from 12-6 and 3-9. At the time, the MSRP was $775. The MSRP has since increased to $795. But I bought this beauty on Amazon.com for only $524.99; after applying the cash-back from my Prime credit card, this watch costs only $498.75. This was "the offer that I could not refuse," to quote from "The Godfather." Accuracy could be better: after only a few days, it is now 7 seconds behind my phone (to which I set my new watch). But I don't really care about that all that much. This is why I rated "accuracy" at 4 stars, but my overall review is 5 stars. My video shows the date changing suddenly at 11:59:59pm, just how I want it; in another photo, you can see that my Seiko changes the date more slowly, which I do not like. This watch is absolutely phenomenally beautiful. If you're on the fence over whether to make this purchase, then I would say "go for it!" You will not find a prettier, more accurate watch at a lower price in ANY store in the entire USA.

Classy and sporty. Great value!
Color: Grey, Color: Grey
Excellent watch for the price. Looks sporty and dressy. More towards dress watch. Blue is dynamic. Strongly recommend blue for sporty feel. I was thinking of aqua terra. This come close to it with a price less than what i would have paid my state tax for omega aqua terra. My only concern is bracelet which i feel kind of OK. Better bracelet design would have made this watch much superior. 21 lug width is awful. Other than that, nothing to complain.
