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

Great Value for Cool Thigh Protection
Color: 02-multicolour (4-pack), Size: XX-Large
For the price, I'm not sure there are better women's boxer shortlettes anywhere. I've tried more expensive brands, and for quality and cooling, these are right up there. I have other bamboo viscose undies that still get gross when I get sweaty in the summer, but these, with the large mesh panel, really help wick away a lot of that moisture, keeping you feeling dryer and cooler. I find that the leg openings are comfortable and don't roll up! and the waist band doesn't dig, nor does it roll down. These do not provide any compression, and I wasn't looking for any. I just wanted some cooling, thigh protecting women's boxers that wouldn't break the bank. These are them! Bonus- I've washed them and put them in the dryer (following their instructions), and they haven't shrunk; they look about the same and are nice and soft.

Great for the entire family but expensive
So far so good. The brand of boxers we had been buying changed their style and construction so we needed to find an alternative. These have held up well so far to multiple weeks of frequent washing and wearing from the entire family. We did size up from the usual 6/M we normally buy and ordered large to prevent the legs from rolling up which worked out great. Our daughter likes the length and how soft the fabric is for wearing under skirts and gym shorts and liners stay put without moving or leaking as another reviewer mentioned. Our son says they are comfortable and fit well being just supportive enough without being constrictive. We all agree that there seems to be not enough fabric in the back as they tend to be much tighter across the backside than the front and that also causes the waist band to ride lower in the back than the front. These have better seam placement than some brands we tried with no seam across the lady bits and no seam down the middle of the back side so they are more much comfortable but the cost is also much higher and that is why we're only giving it 4 stars. These will stay in the rotation until we find something cheaper that both us and the kids like.

Pregnant lady review! Soft, comfortable, cool.
Color: 03-multicolour (4-pack), Size: Large
So soft, comfortable and cool. I'm pregnant and I've gained weight in my legs. I love wearing dresses but my thighs were rubbing together too much. These are perfect to wear under dresses. I also wear them under my bibs at work and it keeps me from getting overheated but I don't have to worry about whether or not my underwear show since they just look like shorts. I wish these came in maternity. I just keep them below my belly. I'll be buying more for sure.

I want to live in these
Color: 01-multicolour (4-pack), Size: Medium
I bought 4 different sets of new underwear. Unfortunately these came last. It’s unfortunate, because if they had come first I would have cancelled all my other orders or returned them and ordered more of these. I never want to wear anything else ever again; these are the comfiest undies I’ve ever owned, I want to live in them. I can wear them under pretty much anything except leggings or very tight pants (but let’s be honest, I don’t wear those anyway.) They are incredibly soft and breathable, they wash well, don’t roll, keep my thighs from rubbing, are comfy to sleep in, and the colors were true to the photo. Just a heads up, they are on the thin side and just a bit see through in the rear. I’m 5’5” 140lbs and the mediums fit perfectly, they go about mid-thigh.

Extremely comfortable
Color: 02-multicolour (4-pack), Size: X-Large
These are by far the softest and most comfortable underwear I have ever owned. The leg portion absolutely does roll up as so many others have mentioned, however, I did not find that to be uncomfortable at all just annoying that they don’t stay in place. I bought these specific underwear to see if it would help alleviate HS symptoms at all. They have definitely helped with wicking moisture away from the skin. More time will tell if it’s truly helpful for HS. For now, I will recommend these. They are thin, breathable, butter soft, wick moisture comfortable and I would buy again…maybe in a different style next time. I have washed them several times and they seem to be holding up rather well so that is also of supreme importance given the cost of the item. Again, I would recommend this item and plan on purchasing more in a different style very soon.
