Start With Maintenance and Downtime Records
Review work orders, alarm histories, breaker trips, operator reports, infrared findings, and industrial electrical repair costs. Compare the results by asset, production line, and failure type.
Do not dismiss nuisance trips or repeated resets as isolated events. They may point to an overloaded circuit, a weak breaker, poor coordination, a motor problem, or unstable voltage. Equipment that needed several repairs during the year should be considered for deeper testing, modernization, or replacement during a planned outage.
This history also helps you judge whether current inspection intervals are working and when to schedule an industrial electrical inspection.
Review Panels, Switchgear, and Motor Control Centers
Electrical panels, switchgear, and motor control centers should receive close attention because small defects can affect large parts of your operation. Qualified personnel should evaluate them for heat damage, loose or discolored connections, corrosion, moisture, dust, worn components, damaged barriers, and signs of arcing.
The review should also cover breaker condition, trip history, fuse selection, enclosure seals, ventilation, and load balance. Compare voltage and current readings with earlier results. Changes may reveal a developing load or connection problem.
Marshall provides industrial electrical maintenance services for power distribution, motor control centers, high- and low-voltage systems, transformers, generators, wiring, and equipment upgrades.
Check Transformers and Distribution Equipment
Review transformers, disconnects, busways, feeders, conductors, and junction points as one connected distribution system. Look for abnormal temperature patterns, oil leaks where applicable, noise changes, damaged insulation, corrosion, poor ventilation, and signs of water entry.
Your review should also confirm that disconnects operate as intended and remain clearly identified. Wiring methods, conduit, cable supports, seals, and hazardous-area components should match the operating environment. Any voltage drop, phase imbalance, or power-quality concern should be documented for qualified testing.
Grounding and bonding deserve their own review. Confirm that inspection and test records are current and that later equipment installation or plant changes have not weakened system integrity.
Evaluate Motors and High-Use Equipment
Motors, drives, starters, controls, heaters, fans, pumps, and other high-use loads often provide early warning signs. Review overload trips, current imbalance, vibration reports, operating temperature, insulation-test history, and repair frequency.
Include lighting and emergency lighting, especially in production, warehouse, exterior, and egress areas. Failed fixtures, damaged wiring, and poor light levels can create both operating and safety concerns.
When electrical findings overlap with worn machinery, coordinated plant maintenance services can simplify industrial electrical work, Mechanical Equipment Repair Services, and industrial equipment installation during the same shutdown.
Use Preventative and Predictive Maintenance Data
Infrared thermography can reveal abnormal heat at connections, breakers, fuses, contactors, and loaded conductors without relying only on visible damage. Marshall’s infrared thermography services help facilities identify conditions before they become larger problems.
Your program may also include electrical testing, cleaning, torque checks, breaker inspection, grounding verification, and comparison with earlier readings. The value comes from trends, not one isolated result.
A 2025 industrial survey found that 61% of manufacturers experienced unplanned downtime during the prior year. In a separate 2024 report, 78% of maintenance professionals said they were supporting preventive maintenance efforts to address downtime.
Verify Backup and Emergency Power
Review generators, transfer switches, uninterruptible power supplies, batteries, emergency panels, and fuel systems. Confirm that test records, load-bank results, alarms, battery condition, fuel quality, and transfer performance are documented.
The review should also verify which loads are truly critical. Production changes or new equipment installation may have altered emergency-power demand since the original design.
Close Safety and Compliance Gaps
Check panel directories, equipment labels, arc-flash labels, one-line diagrams, lockout/tagout procedures, working clearances, and access to electrical rooms. Documentation should reflect current equipment and field conditions.
Review alignment with OSHA requirements, the control of hazardous energy standard, the 2024 edition of NFPA 70E, and your facility’s rules. OSHA still placed lockout/tagout among its ten most frequently cited standards for fiscal year 2025.
Inspection, testing, opening energized equipment, and corrective industrial electrical work should be assigned only to qualified personnel under approved safety procedures. Marshall’s contractor safety program supports that expectation.
Turn the Review Into Next Year’s Plan
Rank findings by safety risk, production impact, failure likelihood, lead time, and repair cost. Build a plan covering preventive maintenance, capital upgrades, spare breakers and other critical parts, equipment replacement, and scheduled shutdown work.
When comparing industrial maintenance contractors, industrial specialty contractors, or search results for “industrial general contractors near me,” look beyond hourly rates. Relevant plant experience, electrical capability, safety performance, outage planning, and the ability to coordinate repair and installation work all affect your real cost.
