The most common household item that requires a 30 amp circuit is a central air conditioner often people living in rvs use 30 and sometimes 50 amp systems to run all the appliances in the vehicle. Determine correct wire gauge in the intersection of amps and feet.

Usually a general purpose house circuit is designed for 20. The n gauge wire s cross sercional area a n in square millimeters mm 2 is equal to pi divided by 4 times the square wire diameter d in millimeters mm. Don t worry calculating the wire size is made easy with the wire size guides below. Always oversize wires if voltage drop is critical.

Determine amount of current in wire. The n gauge wire resistance r in ohms per kilofeet ω kft is equal to 0 3048 1000000000 times. A n mm 2 π 4 d n 2 0 012668 mm 2 92 36 n 19 5. 60 c 140 f 75 c 167 f awg mm copper.

Wire size based on 3 0 36 v voltage drop in a 12 volt circuit. For a maximum of 40 amps you ll need a wire. 30 amp wire size. Current is measured in amperes or amps.

The size of wire required for a given task depends on the voltage being used the amount of amps required and also the distance that power is being transmitted. For the 00 000 0000 etc. 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. We have a chart for 12 volt 24 volt 36 volt 48 volt and 72 volt applications.

The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor. Gauges you use 1 2 3 which makes more sense mathematically than double nought. Awg wire sizes see chart below awg. For a maximum of 30 amps you ll need a wire gauge of 10.
