FAQ

1. Can you use a 200 amp transfer switch on a 100 amp service?
Yes, you can install a 200 Amp Automatic Transfer Switch on a 100 amp electrical service. The ATS acts as a capable pass-through device. However, the entire circuit's capacity will still be limited by the 100 amp main service breaker. It is crucial to ensure all wiring and downstream breakers are properly sized for the 100 amp load.

2. What is the disadvantage of an automatic transfer switch?
The primary potential disadvantage of an ATS is the initial cost, including both the unit and professional installation. Additionally, it requires regular testing and maintenance to ensure reliability during an actual power outage.

3. Is there an automatic transfer switch?
Yes, an Automatic Transfer Switch (ATS) is a standard electrical device. Our YCQ9 series is an example, designed to automatically and safely transfer power loads from a normal source to a standby (generator) source when a failure is detected.

4. What wire size do I need for my 200 amp ATS?
For a 200 Amp ATS, the required wire size depends on the wire material and local electrical codes. Typically, for copper conductors, 2/0 AWG or 3/0 AWG is standard. For aluminum, 4/0 AWG is common. Always consult the National Electrical Code (NEC) or a licensed electrician for the final specification based on your specific installation conditions.
