Testing EPSS Breakers: An Essential Routine Maintenance Practice

Testing requirements are set by the National Fire Protection Association or NFPA 110 standards to ensure the reliability of your Emergency Power Supply System. An EPSS contains multiple electrical switches designed to manage the current being created and sent from this system to devices within your building. For example, circuit breakers are a switch designed to interrupt current flow in situations where an overloaded or short circuit is present. An automatic transfer switch is the component used to connect the primary and standby power sources. The emergency generator might not kick on if this portion of your backup system is not functioning appropriately. Every component in your generator must be tested regularly to make certain this important power source is available when needed.

Dependable system components, a solid maintenance budget, and qualified professionals are required to provide increased startup reliability. Maintenance should be performed based on manufacturer recommendations and NFPA standards for critical emergency electrical sources. Testing of EPSS breakers allows experienced professionals to guarantee these components will properly interrupt current flow when anomalies exist. System evaluations, installation assistance, planning, product selection, acceptance testing, and numerous other services are easily obtainable from a qualified professional in the Georgia area.

Emergency Power in Georgia: Why Is Switchgear Commissioning Performed?

Emergency power professionals in Georgia will run several tests to verify the operation of breakers and switchgear. Breaker tests involve a visual inspection of the component as well as cleaning. A breaker can be opened or an outage can be simulated to verify the operation of these components. Technicians may use various devices to measure current voltage or other flow factors. Transfer switches require regular maintenance in the form of testing, connection verification, dirt removal, and contact inspections. A technician will look for signs of overheating or the presence of extensive contact erosion to determine if contact replacement is necessary. Lack of appropriate switch care is a common reason for system failure. Expert commissioning prevents device damage, increases startup reliability, and confirms current flow will be appropriately handled by these generator components.

Reliable emergency power professionals are well aware of manufacturer recommendations and NFPA 110 standards, and have the knowledge necessary to evaluate the current condition of your system. The goal is to spot problems before the system is used, thus increasing the dependability of a smooth switchover in the event of a power failure. Current testing and servicing requirements set by NFPA standards fall in the preventative maintenance category. You can take other approaches including predictive, reliability-centered, or the highly undesired “run-to-failure” method.
EPSS parallel switchgear, breakers, and automatic transfer switches require specific procedures to be completed for a solid backup source. Switchgear is a vital component for the proper operation of your backup emergency system that should be routinely inspected to ensure safe operation.
