Electrical Maintenance Testing

Ground fault protection testing is required by the National Electrical Code (NEC) Article 230.95 and by most insurance companies. Do you know what your insurance company requires?

DYMAX can perform all necessary switchgear inspections, relay tests, electrical equipment cleaning, and calibration needed to keep your electrical system in optimal operating condition. Our electrical maintenance services and testing programs follow electrical testing standards developed by the International Electrical Testing Association (NETA), recognized by the American National Standards Institute (ANSI) as an accredited standards developer.

DYMAX uses an Inspection and Test Procedures Maintenance Specification that follows NETA standards. Click here to examine a sample of this specificaion.

We have also developed a Maintenance Frequency Guide based on the NETA Matrix.  Click here to view a presentation explaining the NETA Matrix. 

DYMAX electrical maintenance testing services include:

A thorough, scheduled electrical maintenance testing program costs you much less than the impact of switchgear or relay failure, or worker injury or death. For complete electrical power system maintenance and testing services, contact DYMAX.
