Section 1 Product Description1.1 General DescriptionAn automatic transfer switch (ATS) transfers electricalloads from a normal (preferred) source of electricalpower to an emergency (standby) source when thenormal source falls outside the acceptable electricalparameters. Figure 1-1 shows a typical single-linediagram. Figure 1-2 shows a typical transfer switch.Model KEP automatic transfer switches employ twomechanically interlocked enclosed contact powerswitching units and the Kohlerr Decision-MakerrMPAC 1500 controller to automatically transfer systemload to a generator supply in the event of a utility supplyfailure. System load is then automatically retransferredback to the utility supply following restoration of the utilitypower source to within normal operating limits.Model KEP service entrance rated transfer switcheshave integral overcurrent protection supplied on theutility source as standard, which allows installation at thepoint of service entrance and eliminates the need tohave a separate upstream utility source circuit breakeror disconnect switch. Integral overcurrent protectioncan also be selected on the generator source. Refer toSection 1.2, Overcurrent Protection, for moreinformation on overcurrent protection.The transfer switch mechanism provides a positivemechanical interlock to prevent both power switchingunits from being closed at the same time, allowing aninterrupted open-transition break-before-make transfersequence. The transfer switch controller provides ansition transfer sequences to allowadequate voltage decay during transfer operation toprevent out of phase transfers.Note: For the purpose of this manual, the followingnomenclature is utilized:DDDUtility or Normal to indicate the source ofprimary power.Generator or Emergency to indicate the sourceof standby power.Power switching device to indicate theautomatic transfer switch power switchingdevice [molded case (MC) or insulated case(IC) circuit breaker (CB) or switch (SW) in theATS].The Model KEP service-entrance rated automatictransfer switch uses integral overcurrent protectionwithin the enclosed contact power switching units. The100--1200 A rated molded case power switchingdevices used for the utility and generator sources areoperated by an electrically driven motor mechanism inthe transfer switch. The 800--4000 A rated insulatedcase power switching devices used for the utility andgenerator sources are operated by internal drive motoroperators.CUSTOMERLOADUCB UTILITYPOWERSWITCHINGDEVICEW/TRIP UNITSERVICE ENTRANCEAUTOMATIC TRANSFER SWITCH3-POLE MODEL HANICALINTERLOCKg11--133Figure 1-2 Model KEP Service Entrance ATS(ICCB type shown)NNUTILITY CIRCUITBREAKERNSTANDBY GENERATOR SETFigure 1-1 Typical Single-Line DiagramTP-6946 3/16Section 1 Product Description9

1.2Overcurrent ProtectionModel KEP service entrance rated transfer switcheshave integral overcurrent protection supplied on theutility source as standard. Optional integral overcurrentprotection may also be selected on the generatorsource. An upstream overcurrent protection device isrequired on the generator source if the integralovercurrent protection option is not specified on thegenerator side of the ATS.The type of overcurrent protection varies with ATSamperage size and optional features specified.Transfer switches rated 100 A through 200 A usenonadjustable thermal-magnetic type trip units.Transfer switches rated 250 A through 4000 A useadjustable electronic type with long time orinstantaneous trip unit elements with optional groundfault protection elements.1.3 NameplateA nameplate attached to the controller cover on theinside of the enclosure door includes a modeldesignation, a serial number, ratings, and otherinformation about the transfer switch. See Figure 1-3.The serial number is also shown on a label inside thetransfer switch enclosure.Copy the model designation, serial number, andaccessory information from the nameplate to the spacesprovided in the Product Identification Informationsection inside the front cover of this manual for use whenrequesting service or parts.Refer to Section 1.4, Model Designation, for the types ofintegral overcurrent protection that are available for thetransfer switch.See Sections 2.4 and 6.1.2 for more information onovercurrent protection.GM21291Figure 1-3 Typical Transfer Switch Nameplate10Section 1 Product DescriptionTP-6946 3/16
