Each gauge or thickness of wire is capable of carrying a certain level of electrical current without failing. This level varies according to the thickness and rating of a given wire.

How Much Power Can a 22 Gauge Wire Carry

The maximum amperage for a 22-gauge wire is .92 amps for power transmission, according to the Handbook of Electronic Tables and Formulas for American Wire Gauge. For amperage higher than .92 you will require a lower-gauge, or thicker, wire.

Amperage is the amount of electricity moving through a wire.

Dangers of Overloading

If you run more than the recommended amperage through your 22-gauge wiring, you risk an overload of the wiring. This can result in overheating, fire and electrocution as the wiring becomes exposed in your walls and touch insulation, wallboard or metallic elements like screws or nails.

Wire Gauges

With wire gauges ranging from 32 to 0000 with the capabilities of carrying current from .091 amps to 302 amps, there is a proper gauge wire for all needs. Make sure to find the right size for your current load to avoid danger.

Use the right gauge wire for your needs.
