All successful Maintenance Programs start with a Predictive Inspection.
NFPA – ANSI / NETA
all have standards recommending
NFPA 101(00), Sec. 220.127.116.11
Because they are such a key component in the successful operation of your emergency generator, it is recommended that you consider having infrared testing of your transfer switch(es) conducted annually to check for loose connections.
NFPA 70B 21.17.1 Infrared Inspection.
Infrared inspections of electrical systems are beneficial to reduce the number of costly and catastrophic equipment failures and unscheduled plant shutdowns.
NFPA 70B 21.17.2 Advantages of Infrared Inspections.
Infrared inspections are advantageous to use in situations where electrical equipment cannot be de-energized and taken out of service or where plant production is affected. They can reduce typical
visual examinations and tedious manual inspections and are especially effective in long-range detection situations.
NFPA 70B 18.104.22.168
Infrared detection can be accurate, reliable, and expedient to use in a variety of electrical installations. More important, it can be relatively inexpensive to use considering the savings often realized by preventing equipment damage and business interruptions.
NFPA 70B - 22.214.171.124
Infrared inspections are considered a useful tool to evaluate previous repair work and proof test new electrical installations and new equipment still under warranty.
NFPA 70B - 126.96.36.199
Regularly scheduled infrared inspections often require the readjustment of electrical maintenance priorities as well as detect trends in equipment performance that require periodic observation.
ANSI/NETA. - Appendix B – Frequency of Maintenance, Inspections and Tests.
Section 9 Thermographic Survey – every 12 months
NFPA 70B - 21.17.5
Inspection Frequency and Procedures.
Routine infrared inspections of energized electrical systems should be performed annually prior to shutdown. More frequent infrared inspections, for example, quarterly or semiannually, should be performed where warranted by loss experience, installation of new electrical equipment, or changes in the environment, operational, or load conditions.
NFPA 70B - 188.8.131.52
During the initial design stages, thought should be given to EPM, with ease of maintenance and accessibility being of extreme importance in the design considerations and emphasis on access for adequate visual and infrared inspection of all bus bars and joints.

Your facility relies on proper inspection and maintenance for safe reliable operation. From the minute you open the door and turn on the lights you are inspecting the predictable functions of your building systems. Inspection is the most important part of maintenance.
“Just because your facility is working well today, doesn’t mean it will tomorrow. In fact, without proper inspection and maintenance, failure is inevitable.”
When a system or piece of equipment isn’t working as designed or fails, you give it a closer inspection. If a repair is needed, this would be called Reactive Maintenance. You’re waiting for functional failure before taking corrective action. The cost of reactive maintenance is high and indicates a failing preventive maintenance program. This type of maintenance greatly reduces the full life cycle of your equipment.
If a repair is needed on a regular basis to continue reliable operation or at the manufacturer’s recommendation, this would be called Preventive Maintenance. You’re assuming that general maintenance will prevent or stop the failure mode cycle. Only an inspection will prove the effectiveness of your preventive maintenance program.
“Inspections should always inform your maintenance program to ensure the program is effective and efficient. This is one of the many benefits of a Predictive Maintenance Inspection.”
