Hazardous-Location Cord Connector

This copper-free aluminium connector is built for hazardous-location tray-cable runs. It accepts a single cord with a diameter between 1.40 in and 1.74 in and terminates in a 2-1/2 in MNPT box connection. The straight body and silver finish suit industrial and commercial installations that require UL and CSA compliance.

Thermal and Power Characteristics

As a passive mechanical fitting the connector draws no power and generates no heat or audible noise during operation. Its aluminium body dissipates ambient temperature naturally without active cooling. There are no electrical ratings to exceed, so normal use imposes no thermal or acoustic burden on the surrounding equipment.

Standards Compliance and Installation Impact

The fitting is listed to C 22.2 No. 30, UL 2225 and UL 514B, confirming suitability for classified hazardous areas. No external strain-relief accessory is included, so installers must provide cable support separately. The insulated construction is not present, meaning grounding continuity relies on the metal-to-metal thread engagement at the enclosure.

Questions about this item

How do I install the TC250174 connector on a 2 1/2 in MNPT box entry?

Thread the connector into the 2 1/2 in MNPT box opening, insert a cord between 1.40 in and 1.74 in diameter, then tighten the gland nut to secure the cable without an external strain relief.

What maintenance will the copper free aluminum body need in a hazardous location?

Inspect the silver finish and threads periodically for corrosion or damage; replace the connector if the aluminum body shows pitting, cracks or thread wear that could compromise the hazardous location rating.

Which standard limit is reached first under continuous use in a Class I Division 2 area?

The connector is rated to C 22.2 No. 30, UL 2225 and UL 514B; the temperature rating of the cord and the 1.40 in to 1.74 in clamping range define the practical operating envelope.
