The next wire size larger than 4/0 has a cross section of 250 kcmil. A circular mil is the area of a wire one mil in diameter. One million circular mils is the area of a circle with 1000 mil (1 inch) diameter. An older abbreviation for one thousand circular mils is MCM.
American wire gauge size calculator and chart. ... Wire gauge calculations Wire diameter calculations. The n gauge wire diameter d n in inches (in) is equal to 0.005in times 92 raised to the power of 36 minus gauge number n, divided by 39:
The following wire size chart is intended to be a general guide for wire size and amp ratings
The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 Volts, 60°C through 90°C (140°F through 194°F), not more than three current-carrying conductors in raceway, cable, or earth (directly buried), based on ambient air temperature of 30°C (86°F).
You must use the correct size wire for the current (load) requirement of the circuit to prevent the wire from overheating. The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor.

The wire size calculator will give you a very simple and quick solution to the problem of calculating the size of wires and cables for pump applications in golf courses, landscape projects, and agriculture. The requirements of the National Electrical Code (NEC) and local codes must always be followed. Source Voltage
It goes like this. 4 AWG, 3 AWG, 2 AWG, 1 AWG, 0 AWG, 00 AWG, 000 AWG, 0000 AWG. Another way to name this is with numbers, referring to the zeros. That is, 0000 can also be called 4/0, (or, like, 4 zeros, or in wire-nerd-speak, “four-aught”). Where a 4AWG wire is a little ... 3 responses to “ Wire Size, AWG and Funny Numbers ”
