wire size amp rating
You must use the correct size wire for the current (load) requirement of the circuit to prevent the wire from overheating. The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor. Usually,a general-purpose house circuit is designed for 20 amps.

What is the relationship between wire size and amp rating?
Take a look at our ampacity chart to discover the relationship between wire size and amp ratings. Amperage is a measure of the electrical current flowing through a circuit. Current is measured in amperes or amps. You must use the correct size wire for the amperage requirement of the circuit to prevent the wire from over heating.

What size wire do I need for 50 amps?
8 AWG wire has a rated ampacity of 55 amps. That is a perfect wire size for a 50 amp circuit. If you want to have an even safer circuit, you can use 6 AWG wire as the 50 amps wire size. Note: Do inform yourself about the specific characteristics of these wires before you buy one.
How is electrical current measured in amps?
Electrical current is measured in amps. Each wire size, or wire gauge (AWG), has a maximum current limit that a wire can handle before damage occurs. It is important to pick the correct size of wire so that the wire doesn’t overheat. The number of devices connected to the circuit usually determines how much current will flow through the wire.
