Understanding Romex: An Introduction to NM Cable
Electricians widely use Romex, also known as non-metallic sheathed cable (NM cable), as a type of electrical wire for various residential and commercial wiring applications.
Multiple copper conductors, typically insulated with a thermoplastic material like PVC (polyvinyl chloride), comprise Romex.
Romex cables typically come in various sizes and configurations to accommodate different voltage and current requirements.
They are designed to safely transmit electrical power from the main electrical panel to outlets, switches, and appliances throughout a building.
The Composition of Romex: Unveiling Its Inner Layers
The construction of Romex involves several layers that work together to provide insulation and protection.
At the core of the cable are the conductors, which carry the electrical current. Insulation surrounds the conductors, typically color-coded for identification purposes.
Over the insulation, a non-metallic sheathing is applied, providing mechanical protection and resistance against moisture and abrasion.
This outer sheathing is often made of PVC or another suitable thermoplastic material.
The combination of these layers ensures that Romex is durable, safe, and able to withstand the rigors of electrical installations.
