Current is measured in amperes or amps. Standard cable wire sizes by steven mcfadyen on april 9th 2012 iec 60228 is the international electrotechnical commission s international standard on conductors of insulated cables. Find out about cable sizes for electrical use in the uk and 1 5mm and 2 5mm and other electric cables and the current they carry. Amperes enter the maximum current in amps that will flow through the circuit.

Also learn about what electric flexes and electric wires do and protected against overloading. The cable sizing calculator uses the resistance r c from table 35 in as nzs 3008 at 75 c. The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor. Table of common electrical wire sizes and amps or fuse ratings residential sec cable other wire ampacities for 1 3 current carrying conductors in cable earth or raceway for 120 240 volt systems sized between 100 and 400 amperes.

Today we are here with another comprehensive copper and aluminum wire size calculator as we have discussed in detail the topic of how to calculate the proper wire size for electrical wiring. Wire size chart and maximum amp ratings. Voltage enter the voltage at the source of the circuit. 40 x 1 25 14 3 50 14 3 67 amps.

Single phase voltages are usually 115v or 120v while three phase voltages are typically 208v 230v or 480v. Electric cable sizes and amp ratings for the uk electrical resistance and cable rating tables. You must use the correct size wire for the current load requirement of the circuit to prevent the wire from overheating. This is the worse case scenario.

The wire size chart below shows allowable ampacities of insulated 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 air temperature of 30 c 86 f. From table 430 150 they draw 40 amps 14 amps and 3 amps respectively. For motors it is recommended to multiply the nameplate fla by 1 25 for wire sizing.
