Industrial facilities require more advanced electrical services than residential, and even commercial, buildings. Quite often, a need arises for specialized electrical equipment, such as grounding and cathodic protection systems, motor controls, large conduits, and explosion proof wiring. Each of these aspects of your electrical system is important, particularly explosion proof electrical wiring, which is designed for hazardous locations.

If your industrial facility involves the use or creation of flammable gases, dusts, vapors, or flyaway particles, it is essential that you have explosion proof electrical wiring installed. It is equally important to have this setup inspected on a bi-annual or annual basis to ensure its viability as a method of protection against explosive situations that can prove hazardous to the health of your building and the operational capacity of your facility.

The Need for Explosion Proof Electrical Wiring

It makes perfect sense to design your industrial plant to provide a safe, secure, non-explosive environment. Doing so incurs a certain level of expense, but in the end, this financial cost is well worth the time and effort it takes to arrange for an electrician to come in and handle the task for your business.

Since standard electrical wiring poses a risk of igniting combustible, explosive vapors, gases, and particulates, it is essential to have a licensed electrician install proper wiring for your facility. In addition to this installation of industry-grade, explosion-proof electrical wiring, any facility handling ignitable substances should arrange for a bi-annual or annual inspection in order to ensure that all of its electrical equipment is functioning properly and that it does not pose a serious fire hazard.

A Look at the National Electric Code (NEC) Explosion Proof Classifications

The National Electric Code or NEC has provided a definitive explanation of three levels of classified areas that necessitate explosive proof electrical wiring installation. In each case, any industrial facility that falls into one of the classes must take the proper precautions to secure wiring that is not going to become part of an explosive situation.

Class I refers to any location that produces flammable gases/vapors. Class II encompasses all of the locations in a business that are subjected to the creation of a combustible dust. Class III refers to any location in which ignitable fibers or particles are present in the air, whether or not they are self-ignitable.
