The National Fire Protection Association (NFPA) has developed more than 300 codes and standards that are used worldwide in the fire and life safety industry. These codes guide everything technicians in this industry do, providing standardized safety measures for different industries.
In this blog, we’re diving deep into NVPA Code 70 - also known as NEC 70 - or the National Electrical Code.
What is the code?
As the name would suggest, NFPA Code 70 deals with matters of electrical standards. The code was first established in 1987, and it lays out the requirements for the installation and design of electrical systems. All 50 states in the U.S. have adopted some interaction of the code. It was last updated in 2017, and included updates to nearly every page.
Some of the topics covered include:
- Electrical installations
- Circuits and circuit protection
- Wiring methods and materials
- General-purpose equipment, such as switches and heaters
- High-voltage and low-voltage rule classifications
- Branch circuit requirements
- Conduit and cable protection practices
- Temperature ratings for wires and cables
Where is it used?
As mentioned, this code is used in every state. It is often referenced by electricians and builders. Despite its name, it’s important to understand that NFPA codes are not lawas - they are meant to serve as guidelines for industry professionals. However, many parts of this code have been written into local or statewide building codes, making compliance absolutely mandatory.
It can be difficult for the average person to understand the code if they read it, because it is written very technically. But, it’s important to note that a reputable electrician, builder or fire and life safety technician should be well aware of the code and reference it when working with electrical equipment.
What is the impact?
Electrical fires are some of the most common building fires, with an estimated 50,000 home fires caused by electrical issues each year. When NFPA Code 70 is not followed, some of the biggest risks can be:
- Electrical fires
- Electrical shock
- Property damage
- Electrical system failures
With states making many components of NFPA Code 70 legal requirements for new construction or remodels, these risks can be mitigated.
What are the most common violations?
Because this code is so complex, it can be easy to violate. Some of the most common violations to NFPA Code 70 include:
- Faulty wiring
- Overloading outlets or circuits
- Using too many extension cords
- Loose-fitting plugs
It is essential to work with a certified fire and life safety technician who can assess these issues and more when looking at your electrical system during routine maintenance. During a maintenance inspection, professionals can catch these violations in a system before it’s a problem, preventing fires from happening in the first place and protecting your people and property.
