FAQ<\/h2><div class=\"cards\"><div class=\"card\"><h3>What does TC-ER mean?<\/h3><p>Tray Cable \u2013 Exposed Run. Under NEC 336.10(7) it may be run exposed (without conduit) between the cable tray and the industrial machine or equipment it serves. This eliminates the conduit or armour otherwise required for the exposed section.<\/p><\/div><div class=\"card\"><h3>TC-ER versus AWM \u2014 what is the difference?<\/h3><p>AWM (Appliance Wiring Material) is for wiring inside equipment only. TC-ER is a listed cable type for field wiring in cable trays and the exposed run to the machine. If the NEC or the local authority requires a listed tray cable, AWM is not sufficient.<\/p><\/div><div class=\"card\"><h3>What is WTTC?<\/h3><p>Wind Turbine Tray Cable \u2014 a 1 000 V tray-cable rating for wiring inside wind-turbine towers and nacelles. The cable also carries the standard 600 V TC rating.<\/p><\/div><div class=\"card\"><h3>What is MTW?<\/h3><p>Machine Tool Wire, listed to UL 1063. It confirms the cable is suitable for wiring inside machine tools per NFPA 79 (Electrical Standard for Industrial Machinery).<\/p><\/div><div class=\"card\"><h3>Can it be used in Class 1 Division 2?<\/h3><p>Yes. It is listed for NEC 336.10(7) Class 1 Div. 2 per NEC Articles 336, 392 and 501 \u2014 hazardous locations where ignitable concentrations of flammable gases or vapours exist only under abnormal conditions.<\/p><\/div><div class=\"card\"><h3>Is it oil-resistant?<\/h3><p>Yes: UL OIL RES I per UL 1277 and UL 1063, and water-resistant with UL wet approval at 75 \u00b0C. The sheath is also largely resistant to acids and bases.<\/p><\/div><div class=\"card\"><h3>Does it need a screen?<\/h3><p>This cable is unscreened. For EMC-critical circuits, combine with a screened type or add external screening at the installation.<\/p><\/div><\/div>\n<div class=\"contact\"><div><strong>FeiChun Cable \/ \u98de\u7eaf\u7535\u7f06<\/strong><br>Technical and project enquiries: <a href=\"mailto:Tech@feichuncables.com\">Tech@feichuncables.com<\/a><\/div><div><strong>Manufacturing in China, export support<\/strong><br><a href=\"tel:+8613855123218\">+86 13855123218<\/a><\/div><\/div><\/section><\/main>\n<footer><div class=\"wrap\"><div class=\"grid\"><div><div class=\"tag\">FEICHUN CABLE<\/div><h2>UL-listed tray cable: TC-ER, MTW, WTTC and Class 1 Div. 2 in one construction<\/h2><p class=\"small\">For machines, wind turbines, trays and exposed runs on the North American market.<\/p><\/div><div><p><strong>Tech@feichuncables.com<\/strong><\/p><p><strong>+86 13855123218<\/strong><\/p><p class=\"small\">Document FC-ART-TCER-2026-6290.
