Welding Cable Ampacity Calculator

Southwire s voltage drop calculator is designed for applications using awg and kcmil sizes only.

Welding cable ampacity calculator.

Determines wire size to meet specific voltage drop limits or calculates voltage drop for a specific conductor run. The ampacity or amperage capacity is the maximum amount of electrical current that the welding cable can conduct safely. For welding cable application required cable sizes shown in awg numbers. Current is measured in amperes or amps.

For arc welding cable applications length in feet for total circuit for secondary voltage only do not use this table for 600 volt applications. Welding cable ampacities the total circuit length includes both welding and ground leads based on 4 volt drop 60 duty cycle required cable sizes. The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor. Arc one welding lens.

Cable length wire size gauge insulation temperature rating and the type of machine the. 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. Southwire excelene welding cable extra flexible rated for 50 c to 105 c temperatures. 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 equipment grounding conductor.

The welding cable size chart below includes the wire gauge length of the wire diameter weight technical details and color of available. Welding cable ampacities single conductor required cable sizes. The total circuit length includes both welding and ground leads based on 4 volt drop 60. You must use the correct size wire for the current load requirement of the circuit to prevent the wire from overheating.

When sizing conductors calculations limits wire size to voltage drop and nec ampacity. Length is in feet for total circuit for secondary voltages only do not use this table for 600v inline applications. Usually a general purpose house circuit is designed for 20. 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.

Different welding cable running on the same voltage will have different amp ratings depending on several factors which include. Made in usa free shipping over 500. This cable used for secondary voltage resistance welding cable leads national electrical code article 630 electric welders and for temporary power industrial applications.
