FAQs
The TP668 is designed for straightforward installation in compact panels. It features gangable ears for multi-gang configurations, standard 1/2 in knockouts on the sides and bottom, and AC/MC clamps for reliable terminations. Its steel construction provides durable protection, while the lightweight 0.68 lb weight reduces handling strain during mounting and wiring, speeding up field work.
TP668 offers 14 cubic inches of internal capacity with dimensions of approximately 2 in deep, 3 in high, and 2.75 in wide. It weighs about 0.68 lb and accepts two 1/2 in side knockouts plus a 1/2 in bottom knockout, along with two end knockouts. It supports AC/MC clamps for secure conductor terminations and is built to NEC/CEC standards.
The TP668 is ideal for non-hazardous, ordinary locations such as control panels, junction boxes, and small distribution setups. Its gangable design supports scalable panel architectures, while the 14 cu in capacity accommodates typical control wiring. Installation efficiency and reliable protection make it well-suited for retrofit projects and new equipment housings alike.
TP668 complies with NEC/CEC standards and is rated for Ordinary/Non-Hazardous Locations. Canadian certification options are available, and the series aligns with Crouse-Hinds specifications for steel switch boxes. This reduces regulatory risk for cross-border deployments and helps ensure code-compliant installations in diverse facilities.
Using the TP668 can lower maintenance costs through durable steel construction that resists impacts and corrosion in typical environments. Its compact, light design simplifies installation and reduces labor time, while the standardized knockouts and clamps minimize rework. Over time, these factors translate to faster project completion and lower total cost of ownership in control panel applications.
