Wire ampacity calculator enter the information below to calculate the maximum allowable ampacity for current carrying conductors. Current is measured in amperes or amps. Heat caused by an electrical current flowing through a conductor will determine the amount of current a wire will handle.

It just calculates the voltage drop consult the above table for rules of thumb or your local or national electrical code or your electrician to decide what is legal. 40 amps 35 amps. Current carrying capacity is defined as the amperage a conductor can carry before melting either the conductor or the insulation. You must use the correct size wire for the current load requirement of the circuit to prevent the wire from overheating.

8 thhn allowable ampacity. Below is the ampacity for 8 gauge thhn copper building wire available by the foot in several different colors. Use the stayonline wire ampacity chart to look up the rated amperage of different sizes and types of cords. The following calculator calculates the voltage drop and voltage at the end of the wire for american wire gauge from 4 0 awg to 30 awg aluminum or copper wire.

30 amps 25 amps. This amp chart highlights the types of cords gauge size range number of cord coductors ampacity of current carrying conductors and much more. Allowable ampacities of insulated copper conductors rated up to and including 2000 volts 60 c through 90 c 140 f through 194 f not more than three current carrying conductors in raceway cable or earth directly buried based on ambient temperature of 30 c 86 f. The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor.
