The Hammond CSKO664 is a NEMA 1 screw cover enclosure with knockouts, designed for indoor electrical applications where a secure, accessible wiring compartment is required. This type of enclosure provides a protective housing for electrical components, terminal blocks, or wiring connections in light-duty indoor environments. The screw-on cover allows for repeated access during installation, inspection, or maintenance. Knockouts are provided for conduit or cable entry without requiring additional drilling. Licensed electricians and electrical contractors are the primary installers of this enclosure type.
NEMA 1 enclosures are rated for general-purpose indoor use, offering protection against contact with enclosed equipment and falling dirt. The CSKO664 is suited for use in commercial and light industrial settings such as control panels, junction boxes, and terminal enclosures mounted on walls or structural surfaces. This product is appropriate for applications where moisture, dust, or corrosive environments are not a concern.
Designed as an OEM-style general-purpose indoor enclosure for use in residential, commercial, and light industrial electrical installations where NEMA 1 protection is specified.
Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize all circuits before opening or working inside the enclosure. Use appropriate knockout punches or removal tools when opening knockouts for conduit entry. Ensure all unused knockouts are closed with listed fillers to maintain the NEMA 1 rating.
