Automatic Transfer Switches - Single Phase

Check phone pricing on Cummins generators

Click above to check phone pricing

These switches are for use with the automatic standby generators we sell (or in some cases portable generators) 
and 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.

NOTES:
1) If the switch controller requires dc power this usually means you will need a second pair of control wires between the switch and the generator to connect to the starting battery.
2) These automatic transfer switches and controllers indicated with NOTE 2 can be used with portable generators or RV generators.  However, for automatic start to work unattended, all functions including the choke must be automatic or not required.
