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. guy concert tourWebDec 15, 2024 · \$\begingroup\$ 1. yes, depending on what you mean by "needs". There's two problems (heat, voltage loss) that both stem from R, or resistance, which is the answer to the title question. 2. R/distance; longer wire = more resistance, thicker wire = less resistance, you have to balance it to keep R acceptably low for the application. boycott tpmpWebfor a complete cable tray reference source for electrical engineers and designers.
