2 Awg Welding Cable Ampacity

Welding cable ampacities the total circuit length includes both welding and ground leads based on 4 volt drop 60 duty cycle.

2 awg welding cable ampacity.

For 14 awg 20 amperes for 12 awg and 30 amperes for 10 awg copper.

Southwire excelene welding cable extra flexible rated for 50 c to 105 c temperatures. Current is measured in amperes or amps. This cable used for secondary voltage resistance welding cable leads national electrical code article 630 electric welders and for temporary power industrial applications. Ampacity also known as current carrying capacity or current rating is the maximum amount of current that a cable can safely carry without exceeding its operating temperature rating due to the heat generated from losses and ambient heat around the cable welding cable ampacity is a common source of confusion because it is calculated differently than other types of wire and therefore appears to.

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. Welding cable size is measured by the american wire gauge awg standard. 104f and yield load factor of approximately 32 from the 2 awg cable approximately 23 for the 3 0 awg cable and higher for the smaller sizes. 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 awg. Factors tor ambient temperature and number of conductors have been applied. You must use the correct size wire for the current load requirement of the circuit to prevent the wire from overheating. May not be suitable for all installations per national electrical code.

The sizes of cables generally used ranged from 2 awg to 3 0 awg. Or 15 amperes for 12 awg and 25 amoeres for 10 awg aluminum after any correction. The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor. Figure 2 shows a comparison between welding cables in awg sizes and metric sizes.

Awg metric cable size comparison now when selecting the proper cable size for your welding equipment it is best to choose cable that can handle the maximum output of the welder.
