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. 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. 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. Shop Southwire SIMpull 250-ft 6-AWG Stranded Black Copper Thhn Wire (By-the-foot) in the TFFN & THHN Wire department at Lowe's.com. More importantly the table shows Ohms per 1000 feet for the following temperatures 0C, 15C, 20C, 25C, 50C and 75C 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. However the point of the table is to quickly show how the resistance varies. 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.

Minimum AVG Insulation Thickness: 0.91 mm / 0.036 inches Lead-free, flame-retardant, sunlight-resistant Polyvinyl Chloride (PVC) Uninsulated bare annealed copper per ASTM B3 The American Wire Gauge (AWG) measurement system was designed with a purpose: for every three steps in the gauge scale, wire area (and weight per unit length) approximately doubles. The middle letters (HH) indicate its high heat resistance and suitable for high-temperature use up to 90 degrees Celsius. The first letter T shows the insulation is a thermoplastic material made from polyvinyl chloride (PVC).
