1/16/2024 0 Comments Thhn wireIf you require wiring for wet locations, you must use THWN wire. *Data provided on this page is subject to change based on different manufacturers variances. Where can THHN wire be used THHN wire is allowed for use in dry and damp locations only. It comes with a variety of characteristics, the conductor can be stranded or solid, of copper or aluminum, and jacketing can be of PVC insulation with Nylon. These cables are typically used in control circuits, machine tools, and heavy appliances. Nylon Jacket Thickness: 0.100 mm / 0.004 inchesĪllowable Ampacity: 30 Amps at 60✬ / 30 Amps at 75✬ / 30 Amps at 90✬ THHN stands for Thermoplastic High Heat-resistance Nylon coated wire. PVC Insulation Thickness (Conductor): 0.510 mm / 0.020 inches Stranded, uncoated copper conductors per ASTM-B3, ASTM-B787 and ASTM-B8Ĭolor-coded Polyvinyl Chloride (PVC), heat and moisture-resistant, flame-retardant compound per UL-1063 and UL-8 Solid, uncoated copper conductors per ASTM-B3 Institute of Electrical and Electronics Engineers You have to either go with the NM-B cable, or you have to use conduit to put the individual wires in. Encore Wires PVC Jacketed Metal Clad Cable is available in sizes 14 AWG through 750 KCMIL. Its not allowed to just put straight THHN or bare copper loose inside a wall. Sizes 14 AWG - 1000 KCMIL Copper building wire Permitted for 600-volt. All sizes are rated gasoline and oil-resistant II.Ī tough, polyamide, Nylon outer covering per UL-1063 and UL-83. PVC Jacketed MC Aluminum Armor THHN/THWN-2 Inners. THHN / MTW / THWN-2 / T90 is intended for general purpose applications as. THHN wire is typically two-conductor, and found in the familiar ROMEX-style cabling that laces all homes and other structures. Designed to withstand heat up to 194 degrees Fahrenheit, this resistance drops to 167 degrees if oil exposure occurs. Applications requiring Type AWM conductor is appropriate for use at temperatures to not exceed 105☌ in dry locations.ġ0 Gauge Copper Wire, #10 AWG THWN, building wire, 10 gauge hook up wire, conduit wire, bathtub wire, lighting wire, nylon copper wire, construction cable, 10 gauge wire, #10 awg wire, 100' of 10 AWG Wire THHN wire is the original version of the dual-rated cable. Applications requiring Type MTW conductor is appropriate for use in dry locations at 90☌, or not to exceed 60☌ in wet locations or where exposed to oils or coolants. Applications requiring Type THHN or THWN-2, the conductor is appropriate for use in wet or dry locations at temperatures not to exceed 90☌ or not to exceed 75☌ in oil or coolants. Type THHN/THWN-2 building wire is intended for general purpose applications as defined by the National Electrical Code (NEC). Type THHN-THWN-2 is permitted for new construction or rewiring for 600-volt applications.
