Diagram Wire Size. For higher power systems or longer lengths 16 gauge is a great choice. Explanation of wire charts 22 gpt insulation thickness stranding nom.
Every wire except the ground wire is coated with a non conductive coating of insulated material. To calculate the wire gauge with the help of diameter you can use the following formula. Dont worry calculating the wire size is made easy with the wire size guides below.
