Each ungrounded conductor of the service carries 100 amp a piece of the 200 …, Advanced Wire Size Calculator. Enter the information below to calculate the appropriate wire size. Voltage - Enter the voltage at the source of the circuit. Single-phase voltages are usually 115V or 120V, while three-phase voltages are typically 208V, 230V or 480V. Amperes - Enter the maximum current in amps that will flow through the circuit., The actual wire diameter of #14 copper wire can vary among manufacturers and wire types. The wire size table below gives the typical diameter of #14 copper wire as 0.073- .064 / 1.84-1.63 inches / mm. [Thanks to Anonymous for careful editing] , For 100 amp service, you will need to use 3 AWG hot copper wire because it has 100A ampacity. As we will see further on, if you need 100 amp service 50, 100, 150, 200 feet away, you need to use 2 AWG wire with 115A ampacity to negate the voltage drop across the wire. For 100 amp service, you will need to use 00 (2/0) AWG hot aluminum wire ..., Jun 10, 2008 · we just did a church that had a 200 and a 400 disconnect feeding 2 panels on the inside. the plans called for a 2/0 to building steel and a 2/0 to water pipe and a #6 to ground rod. the building was wood framed and incomming water was plastic. we placed 2 ground rods (1 at each disconnect) run a 2/0 to each disconnect from the ground rods and connected the ground rods together with 2/0 cadweld
