2 Welding Cable Ampacity

Table 2 weights and measurements metric.

2 welding cable ampacity. The total circuit length includes both welding and grounds leads based on 4 volt drop 60 duty cycle. You must use the correct size wire for the current load requirement of the circuit to prevent the wire from overheating. Suggested ampacities for 600 volt in line applications. Awg amperes awg amperes 4 0 315 1 170 3 0 275 2 150 2 0 235 3 130 1 0 200 4 110 6 85 per standards.

The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor. 2 0 223 ampacities for portable cable continuous duty ambient temperature of 40 c. This welding cable features better flexibility due to the thinner 34 awg stranding and is stronger than class m wire because of its more durable orange jacket. Current is measured in amperes or amps.

For welding cable application required cable sizes shown in awg numbers. View the awg reference table below for dimensions and sizing of welding cable. Class m welding cable is our premium welding cable. 120 240 volt 3 wire single phase service entrance conductors service lateral conductors and feeder conductors that serve as the main power feeder to a dwelling unit and are installed in raceway or cable with or without an.

Welding cable ampacities single conductor required cable sizes. Class m cable can be relied on for constant service from 50 c up to 90 c. Icea s 19 81 nema wc 3 part 8 appendix j ampacities for portable cable continuous duty ambient temperature of 40c. Besides the cross sectional area other factors that impact the ampacity of welding cable are its length ohm rating i e resistance rating temperature ratings of the insulation.

Item sold by the foot o d. May not be suitable for all installations per national electrical code. Welding cable size is measured by the american wire gauge awg standard. Cable marked with this symbol is a standard stock item ampacities are based on table 400 5 a of the 2017 national electrical code and cec table 12.

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. 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.
