Understanding NFPA 70B Compliance: What It Means for Commercial Electrical Systems
4 Min. Read
Initially introduced in the 1970s by the National Fire Protection Association (NFPA), NFPA 70B outlined recommended practices for maintaining commercial electrical equipment and improving safety. While beneficial, compliance was voluntary for decades.
That changed in 2023 when NFPA 70B was reclassified as an enforceable standard. Businesses that fail to follow it now risk fines, legal liabilities, and increased exposure to safety hazards.
Read on for a detailed NFPA 70B compliance breakdown and a closer look at how this standard makes your facility safer.
What Is New in the 2023 Version of NFPA 70B?
The most significant change is that NFPA 70B is now a mandatory standard for commercial facilities, which means OSHA can use these rules to issue citations. The updated version of the standard also has additional content and definitions.
Electric Maintenance Intervals
NFPA 70B establishes guidance regarding how long you can wait between routine maintenance, which you should use to create a maintenance schedule.
The standard also has provisions for intervals between system studies. These studies look at potential hazards, performance, and NEC compliance, helping you assess which systems might need upgrades or updated maintenance practices.
Condition-Based Maintenance
The 2023 version of the NFPA 70B standard introduces the idea of condition-based maintenance. The guidelines explain how to categorize your different electrical systems into three categories based on their condition.
You can then use this information to determine how often to conduct commercial electrical maintenance. For instance, based on the condition, visual inspections need to happen every six to 12 months, while lubrication intervals can range from 12 to 60 months.
Implementing a predictive maintenance program and engaging in continuous monitoring can help space out these intervals.
What is preventive maintenance?
Under the standard, electrical preventive maintenance focuses on smart features that can monitor equipment health. These can include built-in features in new electrical equipment or add-ons that you implement for online monitoring.
Your Electrical Maintenance Plan (EMP)
Besides introducing the concept of an Electrical Maintenance Plan, NFPA 70B defines the scope of these plans.
We’ll delve into this in more detail below.
What Is NFPA 70B-Compliant Periodic Maintenance?
Electrical equipment maintenance requirements vary from system to system, and the condition also affects the checks you should perform.
Generally speaking, NFPA 70B defines five areas of periodic maintenance in Chapters 11 through 38.
The standard highlights the importance of visual inspections. It breaks down this step into 11 key areas to check, ranging from inspecting insulating material for wires to checking for legible markings on circuit breakers.
Cleaning is another area of focus, followed by lubrication for systems with moving parts.
Next, NFPA 70B explains how to perform mechanical servicing. This includes checking the torque of hardware connections, switching circuit breakers off and on, and verifying mechanical safety interlocks.
You’ll also find detailed guidelines for electrical testing. The standard defines acceptable methods of testing, such as infrared thermography, inverse time trip testing, pickup testing, relay checks, following the manufacturer’s recommendations, and more.
How Does NFPA 70B Define Electrical Maintenance Plans?
NFPA 70B defines what to include in your EMP, but you should customize this plan to reflect the unique needs of your commercial buildings.
It’s also worth noting that, besides addressing compliance requirements, keeping your EMP up to date has several benefits, including preventing electrical fires and outages, avoiding costly damage, and making your building safer.
A compliant EMP should define the scope of your maintenance efforts by listing all relevant electrical systems and their condition.
It should also define who implements the plan and is responsible for specific tasks, such as visual inspections or cleaning electrical equipment. These different tasks should be further outlined, along with compliant inspections, tests, and servicing, organized in an electrical maintenance schedule.
Documentation is another critical area of focus since your EMP should include processes for recording maintenance procedures, listing electrical systems, and keeping records of your personnel responsible for electrical maintenance.
Lastly, there should be room for change and updates, with processes you can follow to add new or upgraded electrical components to the plan and steps you can follow to assess your EMP’s performance and improve it.
