How to Perform a Radiated Emissions Measurement

Radiated emissions testing is the measurement of the electromagnetic field of the emissions that are unintentionally being generated by the equipment under test.

These requirements cover open, enclosed and dead-front switches rated up to 1500 V dc, intended for use in dc photovoltaic (PV) systems and installed in accordance with Article 690 of the National Electrical Code, ANSI/NFPA-70. These switches are intended for ambient conditions between minus 20 to +50°C.
