Commonly installed in industrial facilities, commercial buildings, manufacturing plants, and utility electrical systems, this threadless coupling provides a secure mechanical connection and reliable grounding continuity. Maintenance teams and electrical contractors use this fitting for repair, retrofit, expansion, and replacement of rigid conduit systems. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5ms9th\" data-start=\"634\" data-end=\"651\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"653\" data-end=\"1183\"\u003eThe Thomas \u0026amp; Betts 8524 is designed to couple 1-1\/2 inch rigid metal conduit and IMC using captive set screws, eliminating the need to thread conduit ends. Its steel construction provides a concrete-tight connection while ensuring positive mechanical retention and electrical bonding. The coupling is ideal for electrical raceway installations in switchgear, motor control centers, industrial machinery, commercial buildings, and other applications where conduit rotation is not possible. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1185\" data-end=\"1214\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1216\" data-end=\"2308\"\u003e• Manufacturer Part Number (MPN): 8524\u003cbr data-start=\"1254\" data-end=\"1257\"\u003e• Brand: Thomas \u0026amp; Betts (ABB) – T\u0026amp;B Rigid Fittings\u003cbr data-start=\"1307\" data-end=\"1310\"\u003e• Product Type: Set Screw Coupling\u003cbr data-start=\"1344\" data-end=\"1347\"\u003e• Trade Size: 1-1\/2 in.\u003cbr data-start=\"1370\" data-end=\"1373\"\u003e• Conduit Type: Rigid Metal Conduit (RMC) \/ Intermediate Metal Conduit (IMC)\u003cbr data-start=\"1449\" data-end=\"1452\"\u003e• Installation Type: Threadless Set Screw\u003cbr data-start=\"1493\" data-end=\"1496\"\u003e• Material: Steel\u003cbr data-start=\"1513\" data-end=\"1516\"\u003e• Finish: Zinc Electroplated Chromate Coating \/ Galvanized Zinc\u003cbr data-start=\"1579\" data-end=\"1582\"\u003e• Connection Type: Coupling\u003cbr data-start=\"1609\" data-end=\"1612\"\u003e• Construction: Concrete-Tight\u003cbr data-start=\"1642\" data-end=\"1645\"\u003e• Application: Couple and effectively bond threaded ends of RMC\/IMC where neither conduit length can be rotated; suitable for joining conduit or connecting to threadless openings in boxes and enclosures\u003cbr data-start=\"1847\" data-end=\"1850\"\u003e• Standards: UL Listed (UL File E23018), CSA Certified\u003cbr data-start=\"1904\" data-end=\"1907\"\u003e• ETIM Classification: EC000939 – Coupler for Installation Tubes\u003cbr data-start=\"1971\" data-end=\"1974\"\u003e• Compliance: RoHS 3 Compliant, TSCA Section 6(h) Compliant\u003cbr data-start=\"2033\" data-end=\"2036\"\u003e• UPC: 786210085241\u003cbr data-start=\"2055\" data-end=\"2058\"\u003e• Features: Captive hex-head set screws, positive holding strength, reliable ground continuity, eliminates conduit threading, corrosion-resistant steel construction, and approved for concrete-tight installations. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"1cz0398\" data-start=\"2310\" data-end=\"2334\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"2336\" data-end=\"2405\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e• Thomas \u0026amp; Betts 8424\u003cbr data-start=\"2357\" data-end=\"2360\"\u003e• Thomas \u0026amp; Betts 8624\u003cbr data-start=\"2381\" data-end=\"2384\"\u003e• Thomas \u0026amp; Betts 8523\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e","brand":"Thomas","offers":[{"title":"New","offer_id":51714001568046,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_96b30342-711d-4d7e-8dd4-2aedeca6efba.jpg?v=1770413430","url":"https:\/\/plgautomation.com\/products\/thomas-betts-8524-set-screw-coupling-rigid-conduit-fittings-ea-nsb","provider":"PLG Automation ","version":"1.0","type":"link"}
