MC Cable: Uses and Advantages of Metal Clad Cable

We wrote in an earlier blog about romex wiring, and why it should be a replacement for knob and tube wiring and aluminum wiring for residences. Today, KB Electric LLC will provide useful information on another type of wiring, known as MC cable (metal clad cable).

What is MC Cable?

MC cable (metal clad cable) is a type of cable that typically contains three insulated conductors (wires) encased in a smooth tube, ridged tube, or interlocking metal. The protective outer interlocking metal is flexible, allowing for easy bending. This type of cable can also house any number of conductors, meaning there is no limit by UL standards.

What Is MC Cable Used For?

Metal clad cable can be installed for service, feeder, and branch circuitry. In other words, MC is useful for wiring your main electrical panel from your service head, your sub panel (if applicable) to your main electrical panel, and your individual outlets and lighting circuits from your main electrical panel. MC cable can be used inside and outside, in wet locations when specified, and in concealed or non-concealed areas. 

 

Advantages of Metal Clad Cable (Why Electricians Love This Stuff!)

  • No need for electrical conduit with indoor applications (since it has its own metal “armor”)
  • Cable is flexible
  • Cable cuts easily
  • Many varieties useful for different applications (wet locations where corrosion can take place, direct burial, hospital settings, etc.)
  • Indoor and outdoor use!
  • Permitted in buildings with an unlimited height requirement
  • Commercial and residential use

 

When one of our licensed, master electricians writes up an estimate for you and you see the term ‘MC Cable’ written on there, you now know what it is and its various uses. It’s always beneficial to know the ins and outs of your home’s electrical system, starting with how it is wired, what type of wiring is used, and how to determine any electrical hazards for you and your home’s safety.
