Eaton TP451RED Square Outlet Box - 4-Inch NEC/CEC
Part Number: TP451RED
Quick Summary
The Eaton TP451RED square outlet box is a rugged steel enclosure designed for protected conduit connections in industrial electrical installations. Engineers often struggle with field-fit boxes that crack under vibration, corrode after installation, or fail at knockouts, causing downtime and rework. This unit’s welded construction and durable steel housing deliver reliable performance in ordinary/non-hazardous locations, while its NEC/CEC compliance and Canadian certification references help meet multi-region requirements. The VMS bracket and welded design enable fast mounting and vibration resistance, reducing labor and warranty risk. With a 30.3 cubic inch capacity and a 4-inch square footprint, it also integrates smoothly with standard boxes and covers, supporting scalable panel design and maintenance. Color-coded red helps quick identification in complex installations.
