Instructions:

To determine the effective AWG of multiple wires with a particular gauge.

For example, to see the effective gauge of a cable made from x10 20-gauge wires, select 20 gauge from the drop list, then type 10 into the number of wires field and press the Tab; the combination is equivalent to a single 10 AWG gauge.

Determining how many smaller wires are required to replace a single larger wire.

For example, if you want to create a 12-gauge wire from 20-gauge wires, first select 20 gauge from the Wire Gauge list, then select 12 gauge from the Effective Gauge list; the required number of wires is 6.

Instructions:

This calculator determines the effective gauge of a combination of wires of differing gauges. Select the desired gauge and enter the number of wires of each gauge. (Press the Tab after entering a wire count.)
