Dear Delphiers,

Do you know if we are required to put the gray insulator in between the black and red blocks on the Din Rails distribution system? The FIRST manual doesn't specify, except that the grays must go at the ends of the blocks (understandably). I see no reason for the gray in the middle, as the red and black blocks are already insulated from each other. It seems superfluous. Do you know if we are required to put the gray in the middle to pass inspection? If so, do you know of any loopholes to get around this (an official manual from the actual manufacturer, etc.)?
