**What size wire for AMP?**

Amps (amperage) is the measurement of current required to power an electrical appliance or piece of equipment. Wire size is also important in sizing a circuit breaker. For circuit breakers up to 15 amps, use 14 gauge wire or larger. For a 20 amp breaker, use 12 gauge wire or larger. For up to a 30 amp breaker, use 10 gauge wire or larger.

### How do you calculate wire size?

Derive the formula for calculating the AWG wire sizes. This will be given by the general formula Dn = (D0)r ^((N-(d + n))/N), where Dn is the diameter of n gauge wire, r is the ratio between the largest and smallest wire, N is the number of draws needed to obtain the smallest wire from the l, and d is the offset of the largest gauge from 0.

### How do you calculate conductor size?

The formula for calculating the size of conductors for direct currents, where the length, load, and loss in volts are given, is as follows: The size of conductor (in circular mils ) is equal to the current multiplied by the distance (one way) multiplied by 21.6, divided by the loss in volts; or, CM= C X D X 21.6.(1)

**What is the standard electrical wire size?**

American wire gauge (AWG) is a standard for the width of electrical wire used predominately in North America. The standard specifies the width of the the diameter of the wire, ranging from 0000 to 40.
