In Mass we’re having all kinds of issues with inspectors requiring/allowing an array of different things for 690.12 rapid shut down ranging from roof top disconnects, disconnects on the side of a house 20’ up, disconnects in attics, or only disconnects that can be activated on the ground.  It varies between inspectors.
