  • Which conductor size has the largest diameter?

  • The larger the AWG number or wire guage, the smaller the physical size of the wire. The smallest AWG size is 40 and the largest is 0000 (4/0). AWG general rules of thumb – for every 6 gauge decrease, the wire diameter doubles and for every 3 gauge decrease, the cross sectional area doubles.

  • How to size conductors?

  • Sizing ConductorsThe continuous load current of 80% of conductor ampacity for 3 or more conductors (CEC Rule 8-104),The normal short-term overcurrents that can be safely handled,The voltage drops to be within specified limits to ensure proper equipment operation (CEC Rule 8-102),More items…

  • What size conductors are needed for 100 amp service?

  • There are four provisions for circuits rated 100A or less or marked for 14 AWG through 1 AWG conductors. The conductor selection must be based on one of these four provisions. The first provision instructs us to use a conductor rated 60C. The maximum ampacity for a 60C conductor is listed in the 60C column of Table 310.15 (B) (16).

  • What is relation between size of conductor and voltage?

  • When same power is to be transmitted through a transmission line, size or volume of the conductor would be inversely proportional to the voltage to be transmitted. This is one of the reasons as why we are transmitting the power at very high voltages , the others reasons being reduction in losses, higher efficiency..etc..
