About product
The Briggs & Stratton Dual 200 A/Split 400 A Service‑Rated Automatic Transfer Switch with Symphony Choice safeguards larger homes and small businesses that use 400‑amp split services. By combining two 200‑amp service‑entrance disconnects and a high‑speed transfer mechanism inside one rugged NEMA 3R enclosure, it delivers seamless, code‑compliant power switching while freeing up wall space and install time.
- Dual 200 A (split 400 A) service‑entrance‑rated automatic transfer switch
- Single‑phase 120/240 VAC, 2‑pole open‑transition design
- NEMA 3R powder‑coated steel enclosure for indoor or outdoor mounting
- Symphony Choice™ power management — prioritises up to eight managed loads (including two HVAC circuits)
- Replaces two separate 200 A transfer switches for a cleaner, more economical installation
- Compatible with Briggs & Stratton Fortress, PowerProtect™ and Amplify™ standby generators, plus most 120/240 V sets
- Service‑entrance disconnect breakers, mechanical interlock and clear labelling enhance safety and maintenance
- UL 1008 listed and NEC 2023 compliant
Smart, automatic protection
When utility power drops, the switch senses the outage, starts the generator and transfers both 200‑amp panels in seconds. Symphony Choice continuously balances heavy‑duty motor loads and sensitive electronics so comfort systems, appliances and lighting stay powered without overloading the generator.
All‑in‑one convenience for split 400 A services
Instead of mounting two separate ATS units, installers can now land both utility feeds and both generator feeds in a single enclosure. Pre‑wired current transformers, roomy knockouts and colour‑coded lugs streamline wiring and speed inspection sign‑off.
Built to weather the worst
A gasketed, powder‑coated cabinet shrugs off rain, sleet and snow. Separate breaker compartments satisfy the latest arc‑flash provisions, giving you future‑proof compliance wherever local codes update.
Installer‑friendly layout
Generous lug ranges accept conductors up to 300 MCM, while pre‑installed neutral and ground bars keep terminations neat. A bonding screw is included for quick conversion between service‑disconnect and sub‑panel applications.
