What is the CMA of 14 AWG?
AWG vs. diameter mil, circular mil, diameter in mm and area in mm2.
| American Wire Gauge (AWG) | Diameter (mils) (10-3 in) | Area (circular mils) (CM) (mil2) |
|---|---|---|
| 12 | 80.8 | 6530 |
| 13 | 72.0 | 5178 |
| 14 | 64.1 | 4107 |
| 15 | 57.1 | 3257 |
What is CMA wire gauge?
Cir Mils or CMA = Circular Mil Area which is equal to 1/1000 (0.001) of an inch in diameter or 0.000507 MM.
How much current can you get from 14 AWG?
Size & AMP Ratings
| NM, TW, & UF WIRE (Copper Conductor) | SE CABLE (Copper Conductor) |
|---|---|
| 14 AWG – 15 AMPS | 8 AWG – 50 AMPS |
| 12 AWG – 20 AMPS | 6 AWG – 65 AMPS |
| 10 AWG – 30 AMPS | 4 AWG – 85 AMPS |

What is AWG unit?
AWG or American Wire Gauge is the US standard measure for the diameter of electrical conductors. It means the higher the AWG number is, the smaller the wire diameter is. Our Belden cables and the pairs in instrumentation cable are some of the electrical cables where the conductor size is expressed as an AWG figure.
How thick is a 14 gauge wire?
Share:
| GAUGE | SWG DIAMETER (Inches) | AWG DIAMETER (Millimeters) |
|---|---|---|
| 12 Gauge Wire | 0.1040 in | 2.052 mm |
| 14 Gauge Wire | 0.0800 in | 1.626 mm |
| 16 Gauge Wire | 0.0640 in | 1.290 mm |
| 18 Gauge Wire | 0.0480 in | 1.024 mm |
Can 14 AWG handle 20 amps?
14 AWG must be protected at 15A, according to NEC 240.4(D)(3). 14 AWG can’t be used on a circuit with a 20A breaker. The screw terminals are the better choice if you want to put 15 Amp receptacle on a 20 Amp circuit with 12 gauge wire.
Can 14 gauge handle 30 amps?
How is it safe? A dead short in the #14 branch will draw up to 30 amps of current through the #14 wire. @Bryce: A dead short on the #14 branch would pass a lot more than 30 amps, but would only have to do so long enough to trip the breaker.
How do you calculate CMA?
The CMA Result is calculated by multiplying the price per square foot of your lowest and highest comps to the living area of your subject property creating the range. The CMA Result is the average. Lowest price per square foot comp x number of square feet of subject property = low end of range.

What is AWG in wire size?
American Wire Gauge
AWG or American Wire Gauge is the US standard measure for the diameter of electrical conductors. The American Wire Gauge chart is based on the number of dies originally required to draw the copper down to the required dimensional size. It means the higher the AWG number is, the smaller the wire diameter is.
What’s the normal AWG rating for a wire?
Because of the small gaps between the strands in a stranded wire, a stranded wire with the same current-carrying capacity and electrical resistance as a solid wire, always have a slightly larger overall diameter. The higher the number – the thinner the wire. Typical household wiring is AWG number 12 or 14.
How to calculate circular mil area ( CMA ) of wire?

What’s the difference between AWG and circular mils?
AWG – American Wire Gauge and Circular Mils. Typical household copper wiring is AWG number 12 or 14. Telephone wire is usually 22, 24, or 26. The higher the gauge number, the smaller the diameter and the thinner the wire. The Circular Mil – CM – is a unit of area used especially to denote cross-sectional size of a wire or cable.
What is the AWG number for a house?
Typical household wiring is AWG number 12 or 14. Telephone wire is typical AWG 22, 24, or 26. The table below indicates the current ratings of PVC-insulated single and multicore wiring cables. Be aware that the current load depends on installation method – the enclosure – and how well the resistance heat is removed from the cable.
