Facilities depend on electrical power to operate properly every day. Thorough maintenance ensures the safe, reliable

operation of your electrical equipment. Such regular maintenance and testing can help prevent expensive equipment failures, 

unexpected outages and accidents causing injury or death.  

 

MSG can maintain your electrical system in optimal operating condition by performing all necessary inspections, tests, cleaning

and calibration. Our maintenance and testing programs follow electrical testing standards developed by

NETA (The International Electrical Testing Association), which is recognized by the American National Standards Institute (ANSI) 

as an accredited standards developer.  

 

Maintenance testing may be performed on specific switchgear parts. Contactor operation and circuit breaker close and trip times can be

checked against factory specifications. Sluggish response times could suggest that more thorough maintenance is required.
