Bowtie Engineering’s electrical maintenance keeps your facility’s power systems reliable, safe, and compliant with NFPA 70B — the maintenance standard that became mandatory in 2023. Using a systems-based approach led by licensed Professional Engineers, we combine infrared thermography, power quality analysis, and NETA-standard testing to find problems before they cause outages, equipment damage, or safety incidents. Whether you need a one-time assessment or a recurring program, we document everything for your audits and records.
As of 2023, NFPA 70B is a mandatory standard, not a recommendation. It requires facilities to have a documented electrical maintenance program — with defined inspection intervals, condition assessments, and records — for the electrical equipment their workers depend on. Skipping maintenance is no longer just a reliability risk; it’s a compliance gap. Bowtie builds and runs NFPA 70B-aligned programs so your equipment is maintained on schedule and your documentation is ready when an auditor or insurer asks
The average facility experiences 100 electrical disturbances/transients per month. The result? A System downtime, shortened equipment life, and added expenses.
Businesses need to know the true cost of electrical outages and how they can better maintain their electrical systems.
Our engineers conduct a complete power quality audit and give you a documented snapshot of your electrical system’s health. Each report includes: infrared (IR) thermography with photographs and corresponding thermal images; real-time monitoring of electrical conditions across your distribution system; a breakdown of KW, kVAR, power factor, voltage, amperage, harmonics, and transients; field data documentation; and specific recommendations for upgrades, retrofits, or corrections. You get a clear picture of what’s failing, what’s inefficient, and what to fix first.
Beyond the standard audit, Bowtie performs an Energized System Engineering Analysis on selected distribution components — the difference between a technician taking readings and an engineer interpreting them. This includes ground resistance testing, transformer oil testing, phase-balance measurement, power factor testing, voltage and current harmonics testing, voltage drop testing, and true-RMS measurement. You receive detailed reports with an equipment inventory, written certification of all testing performed, and corrections marked on your one-line drawings. Where it makes sense, we also flag simple-payback opportunities and analyze your utility tariff.
Much of the testing above follows NETA (InterNational Electrical Testing Association) standards — the industry-standard methodology for commissioning and maintaining electrical equipment. Bowtie performs NETA-standard testing and can deploy NETA-network certified technicians anywhere in the United States, giving you consistent, standardized testing across every site. Because NETA is a service buyers search for specifically, we’ve given it its own page with the full detail — acceptance vs. maintenance testing, primary injection, and the standards involved.

Infrared (IR) thermography is the first step in most maintenance programs. A thermal camera finds electrical hot spots — loose connections, overloaded circuits, failing breakers — while your building stays in service, so there’s no shutdown. Bowtie includes IR in our maintenance scope, and every IR job also comes with a report of any code violations we find while the covers are open, at no extra charge. Because IR is a service buyers search for specifically, we’ve given it its own page with the full detail.
A documented maintenance program from Bowtie helps you safeguard personnel, improve system efficiency, reduce utility costs, and minimize unplanned downtime — while keeping you compliant with NFPA 70B. The value isn’t the visit; it’s catching the loose connection, the overloaded circuit, or the failing breaker before it becomes an outage or an injury.
NFPA 70B became a mandatory standard in 2023, requiring facilities to maintain a documented electrical maintenance program. OSHA references maintenance condition when assessing electrical safety, so a documented program is both a compliance and a due-diligence measure.
Intervals depend on equipment type, criticality, and operating environment. NFPA 70B provides the framework; Bowtie sets your intervals based on your equipment and builds them into a recurring program so nothing is missed.
Much of it, yes. Infrared thermography and power quality monitoring are performed with your system energized and in service, so there’s no disruption. De-energized testing (like NETA acceptance or primary injection) is scheduled around your operations.
Both. We provide one-time assessments and recurring NFPA 70B-aligned maintenancecontracts, including IR thermography, NETA-standard testing, and breaker diagnostics, tailored to your facility.
You receive test results, an equipment inventory, written certification of testing performed, corrected one-line drawings, and prioritized recommendations — everything you need for audits, insurers, and internal records.
Bowtie delivers PE-led, NFPA 70B-compliant electrical maintenance, IR thermography, power quality analysis, and NETA-standard testing that catches failures before they cause outages and documents everything for your audits.
