Usually a general purpose house circuit is designed for 20.

2 welding cable ampacity.

Suggested ampacities for 600 volt in line applications. Welding cable class m. Item sold by the foot o d. 2 0 223 ampacities for portable cable continuous duty ambient temperature of 40 c.

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. 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. Class m welding cable is our premium welding cable. The total circuit length includes both welding and grounds leads based on 4 volt drop 60 duty cycle.

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. Welding cable ampacities single conductor required cable sizes. Welding cable size is measured by the american wire gauge awg standard. View the awg reference table below for dimensions and sizing of welding cable.

Table 2 weights and measurements metric. 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. Current is measured in amperes or amps. 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.

Class m cable can be relied on for constant service from 50 c up to 90 c. For welding cable application required cable sizes shown in awg numbers. 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. Icea s 19 81 nema wc 3 part 8 appendix j ampacities for portable cable continuous duty ambient temperature of 40c.

The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor. You must use the correct size wire for the current load requirement of the circuit to prevent the wire from overheating. 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.
