Die cast aluminum construction provides robust weather resistance and mechanical strength, dramatically reducing corrosion and the need for frequent maintenance in outdoor environments. This durable housing prevents moisture ingress and physical damage, lowering the likelihood of electrical faults and unplanned downtime. For engineers specifying outdoor electrical infrastructure, the TP7142 translates to lower lifecycle costs, fewer field failures, and improved reliability in harsh industrial settings. The two-gang configuration with seven 1-inch outlet holes and a 37 cubic inch capacity consolidates multiple outlets into a single rugged enclosure. The result is faster wiring, simplified panel layouts, and reduced cabinet footprint, which cuts project timelines and labor costs for outdoor power distribution. This makes it especially suitable for control cabinets, pump stations, and outdoor lighting circuits that demand compliant, weatherproof protection. With a compact footprint—4.5 inches in length/depth and 4.5 inches tall, plus 2.66 inches wide—the TP7142 fits into tight install spaces without compromising capacity. The design supports compatible weatherproof covers and standard conduit fittings, offering installation flexibility and straightforward retrofits. In field deployments, this translates to fewer modifications and easier future upgrades for process instrumentation or sensor networks in ordinary locations. Compliance and certification credentials provide assurance: NEC/CEC standards govern North American installations, while UL weatherproof certification validates performance in wet and dusty environments. The Ordinary/Non-Hazardous Location classification aligns with typical industrial sites, reducing regulatory risk and easing supplier audits across the US and Canada. This alignment with the Crouse-Hinds Weatherproof portfolio reinforces reliability and safety expectations for outdoor electrical enclosures. From a maintenance and ROI perspective, the TP7142's rugged build, standardized components, and compatibility with common accessories minimize spare-part needs and field adjustments. Operators benefit from improved uptime, safer outdoor power distribution, and a clearer path to scalable enclosures as your facility expands.

FAQs

TP7142 is designed as a two-gang weatherproof outlet box with seven 1-inch outlets and 37 cu in capacity, compatible with standard two-gang outlets and most Eaton/Crouse-Hinds weatherproof covers. It uses a die-cast aluminum body for rigidity and provides reliable gland entries for conduit fittings. This simplifies field wiring, reduces modification needs, and delivers consistent sealing in outdoor installations.
The TP7142 carries NEC/CEC standards for North American electrical installations and UL weatherproof certification for exterior service in ordinary/non-hazardous locations. Canada and US listings support cross-border projects, standardizing compliance during audits and reducing the risk of non-conforming installations. Users should verify cover compatibility and gaskets to maintain full certification status.
Yes. The die-cast aluminum enclosure and weatherproof design are well-suited for outdoor environments, including wet, dusty, and temperature-variant conditions common in industrial sites. The two-gang layout accommodates multiple outlets while maintaining protective enclosure integrity, helping avoid enclosure swaps and ensuring operational uptime for pumps, lighting, and process instrumentation in ordinary locations.
Plan for mounting in constrained spaces by noting the TP7142 dimensions—4.5 in length, 4.5 in height, and 2.66 in width—with a 2-5/8 in depth. Wire entry via rear knockouts and conduit fittings should be sized accordingly, and pairing with approved weatherproof covers ensures proper sealing. Ensure approvals and clearances align with NEC/CEC requirements.
Expected maintenance benefits come from durable die-cast aluminum construction, UL and NEC/CEC compliance, and minimized enclosure count—reducing spare parts and labor. While initial investment may be higher than non-weatherproof boxes, the TP7142 lowers total cost of ownership by extending service life and reducing field repairs, downtime, and replacement frequency in outdoor facilities.
