Answer:
Hey Ray thanks for your question. High pressure spray washers that are cord and plug connected must have factory installed GFCI protection as stated in 422.49. Three phase pressure washers that are operate above 208Y/120 volts are not required to have GFCI protection. There are 3 phase 480 volt special purpose GFCI's available but I don't know if any are rated over 100 amperes.
