FAQs
The CSB120W supports back and side wiring through its screw terminals and brass terminal enclosure. Begin by turning off power, mount the switch flush in the panel, and route conductors (#14-10 AWG) into the back and side entry points. Secure each conductor to the appropriate terminal with a torque of 14 lbf-in. Confirm insulation and strain relief, then re-energize and test for proper operation. This method minimizes wiring crowding and simplifies replacements in crowded panels.
The CSB120W is rated for 20A at 120/277V and supports a wide load range, including incandescent, CFL, LED, ELV, MLV, and motor control loads. It is suitable for commercial lighting, fan control, and small motors. This wide compatibility reduces the need for multiple switch types in a shared panel and simplifies procurement for multi-load environments.
