        There shall be a 300-V limitation on all operating control and signal circuits and related equipment,including door operators. Exceptions are permitted for 25 to 60 Hz ac if the current cannot under any conditions exceed 8 mA, or for dc voltage if the current cannot, under any circumstances, exceed 30 mA.
