Q: Can I use a 200 amp transfer switch if I have a 150 amp main panel?
by Alan Cook from New Jersey on August 06, 2012

A: Yes you can. You might also take a look at the Generac model RTSD150A3 if you are considering installing a Generac generator and purchasing the generator separately..
by Mike, Product Expert

Q: I want to purchase a 6053-0 Generac generator. The client has a 150 amp main breaker in the service panel. Can I replace the 200 amp breaker in the RTSD200A3 transfer switch to a 150 amp breaker?
by Roger J. Ruggieri from New Jersey on January 30, 2012

A: No, the prepackaged models cannot be changed. You will need to purchase the generator and switch separately.
