Speaker wire may be either solid copper wire or stranded copper wire, with stranded wire being the most common usage.Īlso see the Color Codes used on wire Insulation page ColorĬoding of wire insulation based on application.ĭetermine cable length vs. Of course any of those wire gauges will work for a speaker system,īut as the cable run increases the gauge or wire diameter should also increase. Speaker wire is normally around 16AWG, also 18-gauge and 14-gauge are common. Which leads to the two reasons to select the correct gauge wire resistance or Wire Current carrying capacities.ĭata or signaling use resistance per gauge, while power lines use Current carrying ability. So the table provide DC resistance and the link provides AC resistance. This link provides a graph of 24 gauge twisted pair wire 24AWG Frequency vs Attenuation in dB/meters. Its polyvinylchloride insulation makes it oil, gasoline and heat. The first table in combination with the second table offer a good start for selecting a wire gauge for data exchange.Īs indicated 24 AWG is one of the standard wire sizes used to transfer data. THHN 6 AWG Building Wire is constructed with stranded or solid, bare copper conductors. Of course the Diameter in Mils and the Cross-section in circular mils are provided at a standard temperature, 20C. Temperatures are given in both centigrade and Fahrenheit. Note: The maximum load permitted on 1 AWG THHN at 75☌ is 130A 110.14(C) and Table 310.16. More importantly the table shows Ohms per 1000 feet for the following temperatures 0C, 15C, 20C, 25C, 50C and 75C CM 83,690 (1 AWG, Chapter 9, Table 8) VD 460V × 0.03 13.8V K 12.9 ohms, copper D 300 ft. Along with the diameter and cross-section for each gage. The table above provides data for Gage numbers from quadruple ot to 40 gage. So wire gauge needs to be selected at the highest temperature expected, as far as resistance is concerned.Īs wire resistance increases so does cable heating.Īluminum wire properties Aluminum electrical Wire gauge chart page. Wire gauge standard vs Resistance vs TemperatureĪ larger gauge wire may be required at higher temperatures to sustain the same wire resistance. Use these guidelines for Cable Derating to insure the cable functions over the proper temperature range. Of course the table below shows the actual values as they change over temperature.
Applications requiring Type THHN or THWN-2, the conductor is appropriate for use in wet or dry.
6 AWG THHN-THWN-2 is permitted for new construction or rewiring for 600-volt applications.
6 AWG THHN CODE
However the point of the table is to quickly show how the resistance varies. 6 AWG THHN/THWN-2 building wire is intended for general purpose applications as defined by the National Electrical Code (NEC). When you compare the table above with the AWG table below small resistance values may be noticed. More than any other wire size 24 gauge is used by a vast number of electrical interfaces. Interface Buses are #22AWG, #24AWG, #26AWG, and 30AWG. The first Table shows wire gauge vs resistance per 1000 feet.Ī fast and easy way to see the wire resistance changing as the wire gage changes. *Data provided on this page is subject to change based on different manufacturers variances.A quick reference guide to cable resistance for the American Wire Gage.
