The Breaker Wire Size Chart is an important tool for electrical contractors and home owners alike. It provides information about the recommended AWG size for different wire sizes and conductor temperatures. Whether the wire is used in a 50-amp circuit or a 15-amp circuit, it’s important to select the correct wire size.The calculation stands like this: 30 amp wire = 30A x 100% / 80% = 37.5A ampacity. So, with 37.5A ampacity, an 8 AWG wire after 10 AWG wire will perfectly fit 30 amps. The 310-16 code suggests adding an extra 20% of the wire’s ampacity for 30 amps every time the distance increases to 100 feet.The best wire size for a single-phase 120/240V 80 Amp circuit is 4 AWG copper wire (85 Amps ampacity at 75°C) and 2 AWG aluminum wire (90 Amps ampacity at 75°C). These sizes are recommended for a maximum run of 100 feet. The 80 Amp wire size for distances up to 200 feet is 2 AWG copper wire and 1/0 AWG aluminum wire …120-240 volt 30 amp outlet can be installed on 30 amp breaker only/ use 10 gauge wire ... cannot be connected to 15-20-40 amp breaker.
