Across US manufacturing plants, data centers, hospitals, utilities and commercial buildings, electrical switchgear quietly sits at the heart of everything that runs. It controls and protects the critical power that drives production lines, climate systems, lighting and critical processes. Yet for many facility and operations managers, maintaining that infrastructure is treated as a reactive afterthought, not a strategic priority.
The numbers point to a systemic issue. Unplanned downtime is estimated to cost manufacturers around $50 billion each year in the United States, based on Deloitte analysis of maintenance inefficiencies and equipment failure across the sector. At the plant level, the impact escalates quickly.
ABB’s global Value of Reliability survey shows that outages cost industrial businesses around $125,000 per hour on average, with more recent ABB research indicating losses can reach as much as $500,000 per hour depending on the scale and complexity of operations.
Independent benchmarking from firms such as Aberdeen further reinforces the scale of exposure, consistently placing average downtime costs across manufacturing environments in the hundreds of thousands of dollars per hour. Taken together, these figures highlight not only the immediate financial impact of outages, but the cumulative erosion of production capacity, margins and operational performance over time.
OEM partnership: Advantages in proactive maintenance
So what’s driving this level of exposure? In many cases, it comes down to something surprisingly basic: electrical equipment failure. Production is interrupted, costs rise quickly and teams are forced into reactive decisions under pressure.
A significant portion of those failures are preventable with the right maintenance partner in place, and this is the case for partnering with your Original Equipment Manufacturer (OEM) to service and maintain your electrical equipment and switchgear, and why it has never mattered more.
Working with your OEM partner plays a key role in shifting from reactive to proactive management. OEMs bring deeper knowledge of installed equipment, structured maintenance approaches and better visibility across the asset lifecycle – reducing failure likelihood and giving operators more control over risk management.
The difference between an OEM-trained technician and a generalist service provider is not marginal; it can be the difference between a managed repair and a catastrophic event.
NFPA 70B 2023: Mandatory maintenance standards
For decades, electrical maintenance was largely discretionary. Facility teams could decide how and when to maintain equipment. That changed in January 2023. The National Fire Protection Association released a landmark update to NFPA 70B – the Standard for Electrical Equipment Maintenance – shifting it from a "Recommended Practice" to a mandatory “Standard”, meaning electrical maintenance is now a clearly defined obligation.
Key mandates under the 2023 NFPA 70B Standard include:
- Mandatory Electrical Maintenance Programs (EMPs): Facilities must develop, document and operate a formal EMP covering all electrical equipment.
- Mandatory Maintenance Intervals: Chapter 9 defines required scopes of work and inspection frequencies based on equipment condition, ranging from annual to every five years depending on the equipment's physical state, criticality and operating environment.
- Infrared Thermography: All electrical equipment must undergo infrared inspection at least every 12 months. Equipment in the most degraded condition class requires inspection every six months.
- System Study Intervals: Short-circuit studies, coordination studies and incident energy analyses must be performed at intervals not exceeding five years.
- OSHA Enforcement Risk: While NFPA 70B is not directly enforced as law, OSHA can use non-compliance as evidence of a failed practice under the General Duty Clause. If an incident occurs, OSHA will cite what "shall" have been done using NFPA 70B as the standard of care.
NFPA 70B is clear on one critical point: manufacturer guidelines always supersede the standard's minimum requirements. That means the OEM's specifications are the gold standard of compliance, making the OEM the most credible maintenance partner of all.
For facility and plant operators, this regulatory shift has a practical consequence. The question is no longer whether to maintain your electrical infrastructure, but who is best qualified to do it, and how to build a defensible, compliant maintenance record that protects your organization.
Condition-based maintenance framework and cost allocation
Previously, maintenance schedules were “one size fits all.” Every piece of electrical equipment in your facility was maintained on the same calendar interval, regardless of condition. But NFPA 70B 2023 introduced a condition-based framework recognising that not all equipment requires the same maintenance. Your Condition 1 transformer operating in optimal condition can run on extended intervals, while your Condition 3 transformer showing signs of deterioration requires significantly more attention. The difference comes down to a single assessment decision, yet the financial impact can be substantial.
The practical impact is substantial. A Condition 1 asset might require visual inspections every five years. That same asset, degraded to Condition 3 status, now requires inspection every 12 months – five times more often. The testing frequency increases, labor demand multiplies and costs escalate. But here's the critical part: resources are allocated precisely where they are needed most, cutting unnecessary maintenance on healthy assets while preventing catastrophic failures on at-risk equipment.
Reactive repairs cost as much as three times more than planned maintenance. A single unplanned outage can run into hundreds of thousands of dollars per hour. But what's often overlooked is that correctly identifying an asset as Condition 3 early can prevent a costly emergency call tomorrow.
Aging switchgear: Liabilities and TCO escalation
Much of the electrical infrastructure in US industrial and commercial facilities is decades old, creating multiple hidden operational and financial liabilities:
- Spare parts scarcity: Legacy components become difficult and expensive to source, particularly for discontinued or obsolete product lines
- Declining reliability: Aging circuit breakers suffer from degraded lubrication and worn mechanisms, leading to slower clearing times and increased arc flash energy and safety risks
- Compliance gaps: Equipment installed decades ago often falls short of modern ANSI, NEMA, IEEE, NFPA 70E or NFPA 70B standards, creating massive liability exposure
- Mixed-OEM complexity: Facilities operating multiple switchgear brands require fragmented maintenance protocols, specialized training and redundant spare parts inventories, driving up labor costs and human error risk
These challenges compound exponentially. As switchgear ages, Total Cost of Ownership grows driven by spare parts scarcity, arc-flash risk and potential catastrophic failure.
OEM technical expertise, compliance and digital integration
Only the OEM has complete access to original product drawings, design specifications, testing procedures and engineering history. When an OEM technician diagnoses your switchgear, they work from the same data that built it. That depth of knowledge enables faster and more accurate diagnostics, often identifying root causes that generic technicians miss. OEM engineers can also identify opportunities to improve upon original designs, reducing recurring failures and extending equipment life in ways third-party providers cannot.
OEM partners guarantee original spare parts and UL-listed compliance critical safety and legal requirements in the US. Substituting non-OEM parts can void UL listings, compromise system performance and create significant liability exposure.
For mixed-OEM environments, OEM retrofit solutions replace legacy breakers with modern technology without disturbing existing cables, conduits or structures – standardizing a facility's entire electrical distribution system under a single platform, one set of spare parts and one maintenance protocol. The result is lower costs, higher reliability and simpler operations.OEMs are also leading digital transformation.
Modern switchgear monitoring systems capture real-time data on temperature, humidity, load, circuit breaker timing and contact wear. Artificial intelligence and machine learning analyze this data continuously, identifying degradation trends before they become failures.
OEM solutions can generate actionable intelligence and enable less frequent intrusive maintenance while maintaining full NFPA 70B compliance – unlike facilities defaulting to more conservative schedules and frequent disruptions.
The OEM partnership is a strategic imperative
The era of discretionary, reactive electrical maintenance is over. NFPA 70B has made proactive maintenance a legal and safety obligation. Rising downtime costs have made it a financial imperative. And increasing complexity of aging infrastructure has made OEM expertise more valuable than ever.
Partnering with your OEM is not simply about finding the most technically qualified service provider – it is about aligning your maintenance program with the entity that built your equipment, holds the engineering data, manufactures original parts and has a vested interest in long-term system performance. In a world where downtime can cost millions, the right maintenance partner is not an expense. It is the most cost-effective investment your facility can make.
