			 less, shall not be considered to constitute a structure as that term is defined
			 by the National Electrical Code (NEC). The disconnecting means shall not be
			 mounted to the pole. The disconnecting means may be permitted elsewhere in
			 accordance with NEC, Article 225.32, exception 3. SEC special purpose fuseable

			 (time-delay - minimum - 10K RMS Amps 600 VAC) in break-a-away fuse holder
			 accessible from the hand hole. Any poles supporting or incorporating
			 utilization equipment or exceeding the prescribed number of luminaires, or in
			 excess of forty (40) feet, shall be considered structures, and an appropriate
			 service disconnecting means shall be required per the NEC. All luminaire
			 supporting poles shall be appropriately grounded and bonded per the NEC.
