4 Gauge Welding Cable Ampacity

Welding cable size is measured by the american wire gauge awg standard.

4 gauge welding cable ampacity.

Usually a general purpose house circuit is designed for 20. These values for current carrying capacity are based on a copper temperature of 60 c 140 f an ambient temperature of 40 c 104 f and yield load factors from approximately 32 for the 2 awg cable to approximately 23 for the 3 0. You must use the correct size wire for the current load requirement of the circuit to prevent the wire from overheating. The important specs to go by when choosing the appropriate wire that is suitable for your applications are the wire gauge amp voltage rating and the length needed.

View the awg reference table below for dimensions and sizing of welding cable.

Figure 1 lists the awg sizes. Use the stayonline wire ampacity chart to look up the rated amperage of different sizes and types of cords. Awg sizes will have three numbers for example 2 awg 625 30 this means that the welding cable has a total cross sectional area of 2 awg and is made from 625 strands of 30 awg wire. 4 0 the total circuit length includes both welding and grounds leads based on 4 volt drop 60 duty cycle.

Current is measured in amperes or amps. Electrical cable is typically categorized by an awg american wire gauge size where the smaller diameter cable has a larger number. The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor. For welding cable application required cable sizes shown in awg numbers.
