# How Many Amps Will 12 Gauge Wire Carry?

Electricity is usually carried throughout a home and business using wires that are connected to a main electrical source and a fuse box. There are many different types of sizes of wires that can be used, and usually, the wire is measured in gauges by the amount of electrical amps that it can safely carry. A 12 gauge wire is commonly used in kitchens and garages. A 12 gauge wire will typically safely carry around 20 amps.
Reference:
Depending on the insulation type, a 12 gauge wire will carry up to 30 amps, however according to the NEC it can only be used for 20 amps maximum.
