FAQs
The 8432N uses back-wire termination for #12-4 AWG conductors, enabling fast, secure terminations without needing lugs or splice kits. This simplifies panel wiring, reduces field labor, and minimizes the risk of wire insulation damage during terminations, which translates to faster installs and lower defect rates on high-volume electrical assemblies.
Yes, the 8432N carries UL listing and NOM certification, aligned with Federal Specification 6221 02. These certifications indicate compliance with essential safety, performance, and reliability criteria for industrial power connectors used in ranges, dryers, and other heavy-duty equipment.
The 8432N is a three-pole, four-wire configuration with a 15-30P NEMA arrangement. This setup provides a grounded, four-conductor pathway suitable for industrial power distribution to motors, dryers, and other high-draw appliances in manufacturing environments.
With a torque rating of 20–24 in-lbf, the 8432N ensures terminations are tightened to spec, minimizing looseness due to vibration and thermal cycling. This improves connection integrity, reduces arcing risk, and prolongs both plug and receptacle life in continuous-operation facilities.
The plug’s nylon body and brass contacts resist chemical exposure and wear, lowering maintenance frequency. Its robust construction and secure back-wire connections reduce downtime and field service costs, delivering a favorable total cost of ownership for equipment operating in harsh plants, processing lines, and heavy-duty electrical installations.
