an economical means of transferring power double-throw safety switch industrial light commercial residential agricultural
double-throw safety switches eatons double-throw safety switches are used to transfer service from a normal power source to an alternate source, or to switch from one load circuit to another. the manually operated double-throw safety switch provides an economical means of transferring power. eaton offers a full line of general-duty and heavy-duty double-throw safety switches. general-duty eatons general-duty double- throw safety switches are commonly applied in emergency power or generator applications to reduce or eliminate the costly impact of power loss from the typical source in residential, agricultural and light commer - cial markets. all general-duty double-throw safety switches are non-fusible and are available up to 400a. a standby generator connected to a residential wiring system must be installed according to the national electrical code. ? a double-throw switch must be installed to isolate and discon - nect wiring from normal utility lines so that generator-produced electricity is not back-fed onto normal utility lines. whether normal electrical service is disrupted by severe weather conditions, accidents or other issues, an eaton general- duty double-throw safety switch is a critical component in your standby generator applications. heavy-duty eatons heavy-duty double- throw safety switches are designed for commercial and industrial applications. fusible switches are available through 600a, while non-fusible switches are manufactured up to 800a. the wiring configuration from the factory allows a single load to be supplied by a normal or alternate source; however, where necessary, the wiring can be field modified to allow two loads to be alternately supplied by a single power source. heavy-duty double-throw safety switches are designed to accommodate a wide range of accessories that can be factory or field installed. customized solutions, including key inter - locks, viewing windows and receptacles, are also available through eatons switching device flex center. double-throw general-duty non-fusible safety switches dt224urk-nps quick-make, quick-break design, 200a, 240v. double-throw, 240 vac general-duty, non-fusible compact design specifcations ?

chure. each bonding kit comes with applicable materials, hard - ware, instruction sheet and adhesive-backed wiring schematic. the bonding kits can only be used on non-fusible double-throw safety switches. when a bond - ing kit is applied to a three-pole switch, the switch becomes a single-phase switch with single- phase horsepower ratings. a double-throw safety switch with the appropriate bonding kit installed is suitable for service entrance use. typically, a four-pole double-throw safety switch is not suitable for service entrance use; however, with the appropriate bonding kit installed, the four- pole switch is suitable for service entrance use as noted on the device publication of the product. switching neutral bonding kits can also be factory installed by eatons unique switching device flex center. see the end of this brochure for additional information on the flex center. 6 eaton corporation double-throw safety switch 7 eaton corporation double-throw safety switch
