What Type of Electrical Wires Are Used in Commercial Buildings?

Hooking up electrical wiring is easy, right? As long as you know enough not to shock yourself too badly, there’s not much else to it, right? Wrong, and wrong. There’s a lot to know when it comes to electrical work, including commercial electrical wiring in the Dallas-Fort Worth Metroplex, TX.

Some of the things anyone working on electrical systems needs to know include wire sizing, color coding, wire labeling and types of commercial electrical wiring in the Dallas-Fort Worth Metroplex, TX. That’s why it’s a good idea to call a professional like C&F Electrical right from the beginning.

Here are some types of commercial electrical wiring and different aspects about commercial electrical wiring that professional electricians will be familiar with.

Gauge (wire sizing)

When choosing commercial electrical wiring, it’s important to be sure the wire will be the right size for the project. The gauge, or thickness, of a wire determines its capacity for electrical current. The higher the gauge, the thicker the wire, and, therefore, the more current it can handle.

There are risks to choosing an incorrect gauge to complete an electrical circuit. Wires that are improperly matched in regard to gauge and amperage of their circuits will be at high risk of shorting out and causing a fire.

Color coding

The outer sheathing of bundled electrical cables is color coded to easily identify the wires for each connection. This is not to indicate gauge but, instead, is used to signify the preferred use of the wire.

For example, white means a cable is used for 15-amp circuits, while yellow indicates a cable is rated for a 20-amp circuit. Black or red coloring indicates the wires are “hot” connections carrying current, while white indicates a wire designated as a “neutral” conductor. Green and bare copper wires are grounding wires.

Cable labeling

Many electrical cables have information about them printed right on the outer sheathing. This includes info on their wire size, the number of wires inside the cable and type of insulation, as well as any other unique or defining characteristics.

This is a good way to determine the best cable for a given use. It’s also helpful for any electricians looking to fix or upgrade previous installations, as this will give information about the type of connection this cable is used for.

Non-metallic (NM) sheathed cable

The most common type of wiring found in any building is non-metallic, or NM, cable. This is also known by the brand name Romex. It’s made up of at least three wires in a flexible jacket or sheathing and is commonly used for interior circuits like outlets, switches, light fixtures and appliances.
