Dec 1, 2023 · Yellow sheathing indicates NM cable with 12-gauge conductors. Orange sheathing indicates NM cable with 10-gauge conductors. Black-sheathed cable is used for both 6- and 8-gauge wire. Gray sheathing is not used for NM cable but is reserved for underground (UF) cable or service entrance cable (SE or SER).

- Electrical Wire vs. Electrical Cable. Homeowners and electricians alike casually use the terms “wire” and “cable” interchangeably, but there is a significant difference.
- Please, Read the Fine Print. We’re all guilty of skipping the fine print in the User Agreement when we download a new app to our smartphones. But in effect, the information on a wire or cable is an important User Agreement.
- Wire Insulation Color and Sizes. To ensure safety and uniformity, the electrical code requires certain wires to have a specific color. The color green is strictly reserved for grounding and bonding wires.
- Type UF Cable. Type UF indicates underground feeder (UF) and branch-circuit cable. It’s permitted to be installed underground in direct contact with the earth, and in other wet, damp, dry or corrosive locations.
- Romex® Cable. Romex® cable is a brand name for a type of Non-Metallic Sheathed Cable (NM cable) commonly used in residential electrical wiring. It consists of two or more insulated conductors, typically color-coded for identification and a non-metallic sheath that encases the conductors.
- Non-Metallic Sheathed Cable (NM) Non-Metallic Sheathed Cable, commonly known as NM or Romex, is a type of electrical wire that consists of two or more insulated conductors bundled together and surrounded by a non-metallic sheath.
- Armored Cable (AC) Armored Cable, also known as AC cable or BX cable, is a type of electrical wire that combines the benefits of a metallic armor layer with insulated conductors.
- Underground Feeder Cable (UF) Underground Feeder Cable (UF) is a type of electrical wire specifically designed for direct burial applications without the need for a conduit.
Steel Wire Armoured Cable. Steel wire armoured cable, commonly abbreviated as SWA, is a hard-wearing power cable designed for the supply of mains electricity and auxiliary control cable. Used for underground systems, cable networks, power networks, outdoor and indoor applications, and cable ducting. The SWA cable can also be referred to mains ...

Proper electrical wire size is critical to any electrical wire installation. The American Wire Gauge (AWG) system relates to the wire's current-carrying capacity, or how much amperage it can safely handle. When choosing the right wire, you must consider the gauge, the wire capacity, and its intended use.
Most interior wiring is done with non-metallic, or NM, cable—sometimes referred to by a popular brand name Romex. NM cable is made of three or more wires wrapped inside a flexible plastic jacket, or sheathing. It is used for most interior circuits, such as those for outlets, switches, light fixtures, and appliances. The color of the sheathing indic...
Electrical wiring is safe to work on if you observe four basic principles: 1. Work on dead equipment: If the electrical wiring or device is completely dead, it is safe to work on. 2. Lock it out: Make sure the wiring or device, or anything upline (such as a circuit breaker), cannot be accidentally turned on. 3. Test the equipment: Use a voltage tes...
Cable coloring relates to the type of wires inside the cable sheathing and their uses: 1. Black and red: Typically are used for current-carrying or hot connections. 2. White: Usually, grounded neutral conductors. 3. Green and bare copper: Grounding wires.
Electrical wires and cables have markings stamped or printed on their insulation or outer sheathing. These markings provide important informationabout 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. While ...
Standard electrical cable is designed to be run indoors, where it stays dry and is protected by wall, ceiling, or floor structures. For outdoor projects or when running wiring underground, you must use direct-burial cable, which can be installed underground with or without conduit (depending on local building code rules). With direct-burial cable, ...
Stripping electrical wire involves removing the plastic insulation surrounding the wire's metal core. It's important to do this carefully so there is no damage to the metal. The procedure is simple but requires a special wire stripping tooland an understanding of how to use it. This is a critical skill—and tool—for DIYers to have for any wiring pro...
There is a set limit to the number of wiresallowed in electrical boxes. Fill capacity is determined by the size of the box, wire gauges, and the number of devices installed on the box. For safety, it is important to remain at or below the fill capacity. One way to determine wiring fill capacity is to find the box's volume (usually printed on the bo...
The electrical panel, or service panel, is the power distribution point of a home electrical system. This is where all of the individual circuits of the house get their power and where they are protected by breakers or fuses. Wiring an electrical panelis a job for a licensed electrician, but DIYers should have a basic understanding of how a panel w...
An electrical disconnect switch provides a means to shut off the power to a home's electrical system from an outdoor location. It is typically mounted below the electric meter, either on the side of a home or on the utility company's power pole. This is a service disconnect switch.Not all homes have a dedicated disconnect. A disconnect must be inst...
Electrical Wire vs Electrical Cable Electrical Wire. Electrical wire is an assembly of one or more conductors that are insulated but do not have an outer sheath/encasement. The conductors in an electrical wire are either solid or stranded metal conductors.
