The Standard
What NFPA 70B actually requires, and why it’s showing up in your insurance renewal.
NFPA 70B is the National Fire Protection Association’s Recommended Practice for Electrical Equipment Maintenance. The 2023 edition significantly strengthened the language around documentation, maintenance intervals, and the record-keeping a facility is expected to maintain.
Until recently, most facilities managers treated it as background guidance. That has changed. Insurance underwriters use it to evaluate risk. Loss-control organizations reference it in survey requirements. Internal risk and compliance teams cite it when reviewing whether a facility kept documented electrical maintenance records. The question is no longer whether you know about NFPA 70B. It’s whether you can show that you follow it.
The key change in the 2023 edition: NFPA 70B 2023 moved from general guidance on maintenance intervals to specific, documented requirements — written records, condition assessments, and corrective-action documentation for every maintenance activity. Facilities that relied on informal or undocumented maintenance programs now have a gap.
Who Is Asking For This
The people who now expect documented maintenance.
Loss-Control Surveyors
Property Loss Prevention data sheets cite NFPA 70B intervals and documentation requirements during on-site surveys and renewal assessments.
Property Managers & Developers
Writing NFPA 70B language into facility management contracts and requiring documented maintenance records as part of asset handover and annual audits.
Internal Risk & Legal Teams
Using NFPA 70B as the reference point for whether a facility maintained a documented electrical maintenance program.
What We Deliver
A program built to NFPA 70B intervals. Documentation that proves every visit.
NFPA 70B-Aligned Intervals
We assess your equipment types, operating environment, and load conditions against the intervals NFPA 70B recommends, and build a schedule around them, not around what’s convenient or generic.
Written Findings & Condition Ratings
Every piece of equipment is rated, photographed, and documented in writing — in plain language, not raw test data, so your team, your insurer, and your surveyor can all read the same report.
Corrective Action Documentation
Every deficiency gets a corrective-action entry — what the problem is, how serious it is, and what happens next. The record shows not just that you inspected, but that you acted on what you found.
Maintenance History You Own
Your documentation stays with the facility, not with us. Change contractors, bring on a new team, or face an audit. The complete maintenance record is yours. No gaps, no missing reports.
Insurance & Loss-Control Aligned Reports
Our reports are structured to answer the questions an underwriter or loss-control surveyor will ask. You hand them the report. You don’t have to translate it.
Multi-Site Standardization
Manage more than one facility? We run the same program at every site and produce one consistent reporting format across your portfolio, so compliance review is one conversation, not twelve.
Equipment Coverage
The equipment NFPA 70B covers, and that we inspect on every visit.
NFPA 70B applies to virtually all electrical distribution equipment in a commercial or industrial facility. The standard sets recommended inspection and maintenance intervals for each equipment type based on its function, service conditions, and criticality to operations.
- Switchgear and switchboards
- Transformers (dry-type and liquid-filled)
- Motor control centers and variable frequency drives
- Protective relays and trip devices
- Cables, bus ducts, and connections
- Grounding systems and bonding
- Emergency and standby power systems
- Automatic transfer switches
- UPS systems and battery banks
- Panelboards and distribution equipment
The Process
From first call to a maintenance record your insurer can audit.
01
Equipment & interval assessment
We review your facility and equipment list against NFPA 70B recommended intervals to build a maintenance schedule tailored to your systems and risk profile.
02
On-site inspection & testing
Our team inspects and tests each piece of equipment, writes findings on-site, and photographs every asset — condition ratings assigned as we go.
03
Written report delivery
You receive a full written report: a condition rating per asset, corrective-action items ranked by priority, and complete photo documentation, all in plain language.
04
Ongoing maintenance record
Each visit adds to a running maintenance history for your facility. When your insurer or property manager asks for records, you hand them a complete file, not a stack of disconnected reports.
Don’t let your next loss-control survey or policy renewal be the first time you find out there’s a gap.
Common Questions
NFPA 70B compliance questions, answered.
What is NFPA 70B?
NFPA 70B is the Recommended Practice for Electrical Equipment Maintenance, published by the National Fire Protection Association. It defines how often electrical equipment should be inspected and maintained, what a proper maintenance program looks like, and what documentation is required to show the work was done. The 2023 edition significantly strengthened the documentation and interval requirements.
Is NFPA 70B a legal requirement?
NFPA 70B is a recommended practice, not a legally adopted code in most jurisdictions. However, insurers, loss-control surveys, property management contracts, and internal risk and compliance teams increasingly reference it as the expected maintenance standard. Facilities that cannot show documented maintenance aligned with NFPA 70B intervals are finding it affects their coverage, premiums, and renewals.
What equipment does NFPA 70B cover?
NFPA 70B covers virtually all electrical distribution equipment in a facility: switchgear and switchboards, transformers, motor control centers, cables and connections, protective devices and relays, grounding systems, emergency and standby power systems, and UPS equipment. The standard sets recommended inspection and maintenance intervals for each equipment type based on its service conditions and criticality.
How often does NFPA 70B say equipment should be inspected?
NFPA 70B sets recommended intervals based on equipment type, age, and operating environment. For most commercial and industrial facilities, a full electrical inspection every one to three years is the floor. Critical equipment, including switchgear, transfer switches, and emergency systems — is typically recommended for annual inspection. We assess your specific equipment and build a schedule around those recommendations.
What documentation does NFPA 70B require?
NFPA 70B expects written records for every maintenance activity: what was inspected, what was found, when it was done, and who did it. A condition rating for each piece of equipment and a corrective action plan for any deficiencies found are also expected. BASS MCS delivers all of this in every inspection report — in plain language, not raw test data.
How does BASS MCS help with NFPA 70B compliance?
We build and run a maintenance program calibrated to NFPA 70B recommended intervals for your specific equipment and facility type. Every inspection is documented with written findings, condition ratings, and corrective recommendations. The resulting records are structured so your facilities team, insurer, or loss-control surveyor can verify compliance without needing to decode technical test data.
