Select the appropriate diagram and mount theRC Switch. All mounting details and instructions RC switch can be mounted in any position but isusually mounted vertically.

6 Mounting holes in open typeRC Switches accept #10 screws (3/8 inch minimumlength). Enclosure mounting holes accept 1/4 inchdiameter and Load ConnectionsDeenergize the branch circuit to be connected tothe RC Switch and the Control line are reversible. The RC switch is UL listed foruse with 60 or 75 degrees C cable. All power wiresshould enter enclosure adjacent to the RC switchterminals. Combination knockouts are provided onNEMA Type 1 enclosures. Line and load connections aresupplied with clamp type terminals. These terminalsaccept the wire sizes #18 10 AWG Cu.
