The wire size chart below shows allowable ampacities of insulated conductors rated up to and includingĢ000 Volts, 60☌ through 90☌ (140☏ through 194☏), not more than three current-carryingĬonductors in raceway, cable, or earth (directly buried), based on ambient air temperature of 30☌ (86☏). As you can see in this chart, the resistance of the thickest AWG copper wire is 0.04901 milliohms (m) per foot and the resistance of the smallest AWG wire is 1049 milliohms (m). The number of devices connected to the circuit usually determines how much current will flow through the wire. It is important to pick the correct size of wire so that the wire doesn't overheat. Limit that a wire can handle before damage occurs. /rebates/2fb2fElectrical-Wire2fCopper2f42fN-5yc1vZbm7vZ1z0rqh8Z1z0rqh9&. ![]() Each wire size, or wire gauge (AWG), has a maximum current *Data provided on this page is subject to change based on different manufacturers variances.Electrical current is measured in amps. Stranded, uncoated bare copper conductors per ASTM-B3, ASTM-B787 and ASTM-B8Ĭross-linked polyethylene (XLPE) insulation per UL-44 4 AWG XHHW-2 Specifications*: Solid Bare Ground Copper comes in variety of lengths and. 4 Solid Bare Copper Wire contains 99.999 Copper (CU) Conductors. 4 AWG Bare Copper Ground Wire for residential electrical systems.

UL 1685-FT4/IEEE 1202 (70,000 Btu/hr) Flame Test (1/0 AWG and larger) This general purpose wire is used to supply an electrical current in a range of indoor wiring projects, including control circuits and appliances. Our 088805 4 gauge wire is part of our Prysmian Group line. 1/0 AWG and larger are rated for cable tray use and comply with IEEE 1202/FT4 (70,000 Btu/hr) flame test and ICEA T-29-520 (210,000 Btu/hr) flame test.Ĭanadian Standards Association C22.2 No. 6 AWG and larger rated Sunlight Resistant in all colors. 4/0 AWG, THHN/THWN-2, Stranded Copper, 600V, Yellow, 5000 ft Reel. For 1 AWG through 4/0 AWG, sequential foot markings on master reels only unless otherwise specified. Then, divide the total wattage by the voltage of the system, typically 120 or 240, and that will give you the required current or amps. On 250 KCMIL and larger, sequential foot markings located every foot for easy measuring. To calculate the load requirement for a circuit, first add up the wattage of all the electrical devices that will be on the circuit. Suitable for applications requiring low-leaking circuits and a dielectric constant of 3.5 or less.Īvailable in sizes 14 AWG through 1000 KCMIL. 4 AWG commercial wiring - Sold by the Foot (continuous) Add the Length Desired In Feet as Your Quantity and Add To Cart. Type XHHW-2/RW90 is permitted for 600 volt applications and can be used in wet or dry locations at temperatures not to exceed 90✬. ![]() Type XHHW-2/RW90 building wire is intended for general purpose applications utilized in conduit, underground in conduit, or other recognized raceways for services, feeders, and branch-circuit wiring as specified in the National Electrical Code (NEC).
