Junction boxes shall be placed near the base of each light as shown in Standard Drawing 5-22 (SD 5-22). If the power source is within twenty feet of the street light, this junction box will notbe required. All junction boxes used for the street lighting system shall have the words STREET LIGHTING displayed on the metal lid. (See Section 502 ofthe City Standard Specification for additional details.) Junction boxes shall notbe placed in sidewalks or ramps. If there are more than four conduit stubs going into the junction box, the box shall be upgraded to a junction box number 2.
