is not responsible for its accuracy or reliability. As a guide, 14 wire is good for 15 amps, 12 wire is good for 20 amps, 10 wire is good for 30 amps. Electrical current is measured as ampacity. The gauge of the wire indicates the amount of current that can safely pass through the electrical wire. Its diameter measures 0.1019 inches (or 2.588 mm). For instance, common sizes include 14-, 12-, 10-, 8-, 6-, and 2-gauge wire. ![]() Likewise, when the length of the cord exceeds fifty feet there is a decrease in amperage. You can also use the same wire for 35 amps, provided you follow certain considerations. ![]() When a cord has three current carrying conductors there is a decrease in amperage. Generally, 30 amps is the best ampacity designed for 10 gauge wires. The amperage rating of a cord is a function of the wire gauge, number of current carrying conductors and length of the cord. Multiple Conductor Correction FactorsÄisclaimer: The information shown here has been assembled from sources believed to be reliable, but is not guaranteed by Cooner Wire Co. The 10 gauge amp capacity is different at different temperatures: 30 amps at 140 degrees F (60 degrees C) 35 amps at 167 degrees F (75 degrees C) 40 amps at 194 degrees F (90 degrees C) In most situations, the 35-amp circuit is a suitable power rating for the 10 gauge wire parameter. UL General-Use Circuit Ampacity Reference Chart. Multiply the ampacity rating from above by the correction factor listed below to determine the ampacity rating of a conductor in a multi-conductor cable. Current carrying capacity is defined as the amperage a conductor can carry before melting either the conductor or the insulation. 14 Gauge Wire Amp Rating Diameter: How Thick is 14 Gauge Wire 2023 Guide, Blue 14 AWG Primary Wire 25Pacers marine wire is designed to handle the.
