Here is what gauge wire is used for houses:
14-gauge: It uses a 15-amp breaker and is mostly used for lighting circuits.
12-gauge: Perfect for general-purpose circuits and regular outlets. It typically operates on a 20-amp breaker.
10-gauge: It operates at 30-amp breakers. It is necessary for larger, more powerful equipment, such as water heaters, electric dryers, and some cooktops.
6-gauge: The largest equipment, such as electric ranges, usually requires a 50-amp breaker and 6-gauge wire.
What gauge wire is used in houses depends on the amperage of the circuit and the load it will support. Having the right size is essential for preventing fires.
