Automatic Transfer Switches
Cummins 3 phase

 


click above to return to the Cummins main page

 

These switches are for use with 3 phase (or single phase) automatic standby generators of many standard voltages and include many adjustments and features not available on the single phase switches.  These should be installed by a qualified electrician or electrical contractor.  Local permits may be required.
Remember that the transfer switch current rating must be at least high enough to carry full rated load of
your generator.  It also must match or exceed the current rating of the upstream breaker or fuse protection
that will supply normal utility power.  Most jurisdictions do not require the transfer device to switch the
neutral.  Therefore these prices do not include the extra pole for that purpose.  If your local codes or
application requires the neutral to be switched contact us for a special quote.  We can also provide
  custom enclosures to house these switches if you have harsh environments.
