About 200-225A Transfer Switches
200A transfer switches are the residential standard — the correct match for homes with 200-amp main service. This collection includes Generac's RXSC200A3 service-entrance ATS, Kohler RXT, Tigo TSS-200 models, and Reliance Controls manual options, in NEMA 1 indoor and NEMA 3R outdoor-rated enclosures.
A service-entrance-rated 200A ATS installs between your meter and main panel and switches the entire house — no sub-panel, no circuit picking. Pair one with any 20-26kW standby generator for true whole-home automatic backup.
Frequently Asked Questions
How do I know if I need a 200A transfer switch?
Match the switch to your main breaker, not your generator. If your main panel has a 200A main breaker (standard in most homes built since the 1990s), you need a 200A service-rated transfer switch for whole-home backup. Homes with 100A service should use a 100A switch instead.
What's the difference between service-entrance and standard ATS?
A service-entrance-rated ATS includes a main disconnect and is rated to sit between the utility meter and your panel, replacing the meter-main or main breaker position. That's what enables whole-home transfer. Non-service-rated switches install downstream and typically feed a selected-circuits sub-panel.
Will a Generac ATS work with a Kohler or Cummins generator (or vice versa)?
Automatic transfer switches use manufacturer-specific control wiring and signaling — a Generac ATS is engineered for Generac generators, Kohler RXT for Kohler, and so on. Match the ATS brand to your generator brand unless the product page explicitly states cross-compatibility. The Tigo TSS-200 models listed here support generator integration as specified on each listing.
Indoor or outdoor installation?
Either — pick the enclosure to match. NEMA 3R models are weather-rated for exterior mounting next to the meter or generator; NEMA 1 models are for garages, basements, and utility rooms. Most whole-home installs use NEMA 3R at the meter location.
Can I install a 200A ATS myself?
This is licensed-electrician work. A 200A service-entrance installation involves the utility meter, service conductors, grounding electrode system, and an electrical permit with inspection in virtually every US jurisdiction. The NEC requires it, your utility requires it, and your generator warranty may depend on it.
How do transfer switches ship?
Most 200A ATS units ship by standard parcel or freight depending on weight — a service-rated 200A switch in a steel NEMA 3R enclosure runs 60-100 lbs. In-stock units typically leave the warehouse within a few business days.
