Understanding Romex 10 3

Romex 10 3 is a specific type of Romex cable that consists of three insulated conductors and a bare copper ground wire. The "10" in the name refers to the gauge of the wire, which is 10 AWG (American Wire Gauge). The "3" indicates that there are three insulated conductors, typically used for 120/240-volt circuits. This type of cable is commonly used for applications such as:

Powering electrical outlets and switches
Connecting appliances and lighting fixtures
Supplying power to subpanels and other electrical equipment
