Choosing the correct indoor wires requires attention to wire gauge, insulation type and application. Indoor Wires require careful consideration in gauge selection due to current-carrying capacity. The wire’s insulation type also affects its safety and durability in different environments. For indoor applications, wires with PVC insulation can be used for standard installations, while those with higher ratings should be used for special applications. These elements will help ensure that all requirements are met, as well as maintaining the local electrical codes.
