Thomas Betts NC14126 Polycarbonate Enclosure 12x14x6 Nema 4X

Product Description

The THOMAS BETTS NC14126 is a standard polycarbonate electrical enclosure rated for NEMA 1, 2, 3, 3S, 3SX, 3X, 4, and 4X environments. It measures 12 inches wide by 14 inches high by 6 inches deep and weighs 7.16 pounds. The clear polycarbonate construction provides impact resistance while allowing visual inspection of interior components without opening the enclosure. A flat hinged cover secured by captive screws and fitted with swing panels makes access straightforward during service calls. Electricians and controls technicians install this enclosure to house terminal blocks, PLCs, relays, and other low-voltage or line-voltage control components in both indoor and outdoor applications.

This enclosure suits residential and light commercial electrical installations where moisture, dust, and occasional hose-directed water exposure are concerns. The multi-NEMA rating makes it appropriate for indoor general-purpose use through outdoor weatherproof and corrosion-resistant duty. Typical applications include junction and pull boxes, automation control panels, instrumentation housings, and utility disconnect enclosures. Its transparent cover is particularly useful in pump control, pool equipment, and HVAC control wiring scenarios where technicians need to read indicator lights or check wiring status without breaking the seal on every inspection visit.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and applicable local codes. Disconnect and lock out all power sources before opening any existing enclosure or beginning wiring work inside this unit. Use appropriate conduit fittings and knockouts rated for the NEMA environment to maintain the enclosure integrity rating. Avoid using metal drill bits or abrasive tools directly against the polycarbonate body, as gouging or cracking can compromise the impact resistance and environmental seal.
