Types of Commercial Electrical Wiring: What You Need to Know

Keep your business up and running with electrical wiring that works for you. Commercial electrical wiring comes in all kinds of shapes, sizes, and types. But the basics stay the same. You need electrical wiring that’s up to code, safe, and efficient. Here’s everything you need to know about the different types of commercial electrical wiring, what they’re used for, and how to pick the best options for your business.

Non-Metallic Sheathed Cable

Non-Metallic Sheathed Cable (NM) is a type of commercial electrical wiring used in residential and commercial buildings. NM cable is an electrical wiring method in which several insulated conductors are bundled together in a single cable. The cables are enclosed in a nonmetallic sheathing. This of which protects from moisture and mechanical damage.

NM cable is available in various sizes and colors, and they come with insulation ratings for both hot and neutral conductors. NM cable should never be used in high-temperature or hazardous areas due to the enclosed nonmetallic sheathing’s amount of flammability.

Conduit Wiring

Conduit wiring is an important type of commercial electrical wiring. It involves the use of metal or plastic conduits to contain and route wires and cables. This type of wiring is used to protect the electrical wiring, so it is especially important in places where there are wet or hazardous conditions.

It is also used when multiple circuits need to be separated from each other and when extra protection is needed against physical contact and electromagnetic interference. This type of wiring has two types of materials. One is the rigid metal conduit (RMC) and the other is the intermediate metal conduit (IMC).
RMC is more durable and offers a higher degree of protection. IMC is more versatile and less expensive. The conduit and its associated components must meet the standards set out by National Electrical Code (NEC) and other safety standards.

Mineral-Insulated Copper-Clad Cable

Mineral-Insulated CopperClad Cable (MiCc) consists of a copper conductor in an environment insulated with a solid metal such as magnesium oxide. MiCc is typically used outdoors or in applications where superior fire resistance is required. But it can also be used for low and high-voltage circuits.

MiCc is a safe option compared to other wiring methods if they become damp or corroded. Its use can reduce the cost of labor since the key property of MiCc is it is durable and long-lasting construction. This of which makes it ideal for applications where maintenance and repairs are needed.
MiCc also provides a high degree of protection from:

  • electrical shocks
  • vibrations
  • other environmental influences

This makes it a preferred choice for particular industries. It’s important to remember that when using MiCc, the type of conductor should be selected based on the current it is expected to carry and the environmental conditions it will be exposed to. But if you are not sure if this is the right cable for you, don’t hesitate to find a website for structured cabling installation.
