Different types of electrical wires and their uses.

Types of electrical wire there are mainly 5 types of wire. It helps to understand a few basic terms used to describe wiring. Solid wires are rigid and conduct electricity better. This guide describes the different types of electrical boxes their materials and their applications.

Nm and nmc conductors are composed of two or more insulated conductors contained in a non metallic sheath. The coating on nmc cable is non conducting flame resistant and moisture resistant. The electrical wiring system in most homes is created with non metallic sheathed wire nm. Joint box or tee or jointing system.

In older homes the electrical system is likely made up of single conductor wires. Romex is a common type of residential wiring that is categorized by the national electrical code nec as underground feeder uf or non metallic sheathed cable nm and nmc. Electrical wires and cable have markings stamped or printed on their insulation or outer sheathing. These markings provide important information about the wiring and insulation including the wire size and material the type of insulation the number of wires contained inside a cable and any special ratings or characteristics of the wire.

There are two variations. Today however much of electrical wiring is done with multiconductor cables because of their convenience of use. Single conductor wires are the most common type of electrical wires.

Electrical boxes also known as junction boxes enclose wire connections they help protect against short circuits which can cause fires. You will find stranded wires in many common electronics such as cell phone chargers because they are flexible. They are composed of two insulated aluminum wires wrapped with a third bare wire which is used as a common neutral. Understanding electrical wiring labeling.

Triplex wires are usually used in single phase service drop conductors between the power pole and weather heads. Commonly called romex this wire has 2 3 conductors as well as a bare ground wire and it s coated in. An illustrated explanation of the differences between single conductor wires and multiconductor cables. We ve separated the guide into two sections.

Check with your local building inspector before you start any electrical wiring and cable project and be sure to obtain required permits. Types of electrical wiring. What is electrical wiring different types of electrical wiring systems. Aslan alphan getty images.
