FIGURE 2. CUMMINS AUTOMATIC TRANSFER SWITCH (ATS)
Before beginning the installation of the transfer switch, verify that the unit was
correctly selected. Check the following features:
• Specifications (voltage, amperage, frequency, poles, and phases)
• Enclosure (indoor vs. outdoor)
• Model
Cummins recommends that any RA series transfer switch be used with these
generator sets. Refer to the appropriate RA series ATS owner manual for more
detailed information.
Choosing a Transfer Switch
This section includes block diagrams showing partial or full load coverage for the
Cummins RA Series transfer switches. For more information, see the RA Series
RA112L1 Automatic Transfer Switch Owner Manual (A052S254) or the RA Series
Automatic Transfer Switch Owner Manual (A046S594) (models RA112N3,
RA212N3, RA112S3, RA212S3, RA412N3, and RA412S3).
NOTICE
These generator sets can be used with either service entrance transfer
switches or non-service entrance transfer switches.
