I?m over seeing an electrical rehab at one of out golf courses, and a question came up. Do we need a bollard in front of the main disconnects in a cart barn? There is potential of a cart running in to this panel. I would like to see a bollard in front of this panel but our budget is so tight that there may not be money here to supply this bollard. Do we need this bollard? Where does it state it in the NEC code?
