FAQs
CS320BK installs on standard wall plates and backshells used in commercial panels. Wire #14-10 AWG conductors to the screw terminals using the side-wire method, ensuring a clean termination with copper alloy terminals. The device’s 1.3 in depth and 4.2 in height fit common enclosure dimensions, while its 0.902 in width keeps it compatible with most standard cutouts. Proper torque and clear labeling reduce service calls and improve commissioning speed.
The CS320BK is rated for 20A at 120/277V, making it suitable for lighting and general-purpose commercial circuits. Its three-way switch capability supports versatile control configurations, and the side-wire/screw-terminal design eases field terminations for reliable, safe operation in busy commercial spaces.
Yes. With a 20A rating and 120/277V compatibility, the CS320BK is well-suited for commercial lighting control in offices, retail, and hospitality environments. The three-way capability enables flexible control schemes, such as upstairs/downstairs or zone-based lighting, while the wall-mount format fits standard electrical boxes.
The CS320BK carries cULus Listed certification, NOM, and Federal Specification Classification 6241 05, which collectively support safety compliance, traceability, and procurement standardization for regulated facilities. These certifications ease audits, enable safer product selection, and align with facility safety programs.
Maintenance is minimal due to solid copper alloy terminals and a durable PVC body, reducing contact resistance drift and corrosion risk. The 0.031 in terminals and screw connections simplify future re-termination, lowering maintenance time and inventory complexity. ROI improves through fast installations, reduced field failures, and compatibility with standard commercial circuits.
