Can I install Fiber Optic Cable with Electrical Cable in the same Tray?

This is a very common question and when you start poking around on the internet you’ll find a few different answers to the question if you can install fiber with electrical cable. The best place to go for a question like this is the National Electric Code. Let’s go into Article 770 that covers Optical Fiber Cables, more specifically section 770.133 titled Insulation of Optical Fibers and Electrical Conductors.

Nonconductive optical fiber cables, for example, indoor/outdoor rated fiber shall be permitted to occupy the same cable tray or raceway with conductors for electric light, power, Class 1, non-power-limited fire alarm, Type ITC, or medium-power network-powered broadband communications circuits operating at 1000 volts or less. Conductive optical fibers cables, for example, indoor armored rated fiber shall not be permitted to occupy the same cable tray or raceway with conductors for electric light, power, Class 1, non-power-limited fire alarm, Type ITC, or medium-power network-powered broadband communications circuits.

Let’s get a better look at these two cables from our YouTube Channel.

Indoor/Outdoor Fiber Optic Cable

Indoor Interlocking Armored Fiber Optic Cable

As you can tell, the armored cable will cause an issue if there ever was a problem and can help start a fire and as you know smoke inhalation is the number one cause of death in a fire. There are a couple of other things to know about running fiber cable and power into the same cabinet. If you’re going to be doing an installation like that contact your sales representative to go over your installation. For more information on Article 770 order your National Electric Code book.
