Eaton���s CL Type Combination Arc Fault Circuit Interrupter is a device that includes all the protection offered by the Branch/Feeder AFCI. Combination AFCI���s can therefore mitigate the effect of low current arcs not only in the installed wiring but also in the two wire cord sets and power-supply cords connected to the outlets. CL Breakers are classified replacement circuit breakers considered suitable, by underwriter���s laboratories, for use in another manufacturers panel board. These breakers have been tested extensively in numerous GE, Square D and Siemens, Murray Thomas and Betts and Crouse-Hinds panels. AFCI���s are required in all 120-Volt, single-phase, 15 Amp and 20 Amp branch circuits supplying outlets installed in dwelling unit family rooms, dining rooms, parlors, living rooms, libraries, dens, bedrooms, sun rooms, closets, recreation rooms, hallways or similar rooms or areas shall be protected by a listed arc fault circuit interrupter, combination-type, installed to provide protection of the branch circuit.
