Low Voltage, Low Frequency Harmonic Emission Limits

The high end of the Class B range, which is 1.5 kw, represents 12.5 amps at 120 VAC, so for up to 12 amps, the professional and Class B limits could be considered identical. For the range of current between 12 and 16 amps, there may be occasions when professional type equipment is fitted with a 20-amp plug and used with a 20 amp receptacle. ................
