Important: Existing pole is a type-2A which has a 15FT horizontal measurement from the center of the vertical shaft to the end of the mast arm, not a Type-2D which has an 18 FT measurement. The reference to a Type 2D is continuously noted in the drawings, on Sheet A1, keynote 12, Sheet A2 note 7, Sheet A3 keynote 10, sheet E2 keynote 10, and drawn on sheet S1 box 1, the horizontal measurement needs to be changed to 15 FT which indicates a Type 2A pole. Keep in mind if the contractor brings a type 2D mast arm for this location it will be rejected. 3. This streetlight pole installation is utilizing single phase 480 volt power: For all installations with this voltage... On Sheet G-1, N.T.S 5 "Grounding details"... The drawing is indicated as a representation of grounding, this includes "bonding" of metal parts all the way back to the load center. What needs to be illustrated is that the #4 bare solid Cu"UFER" ground in the pole foundation is connected to the ground lug on the pole, and to the #8 bare solid Cu "bond" wire which goes to the City "J" box or pull box. Per discussion with Brian Cunningham the AT&T transformer can be grounded to the ground rod at the pole. This streetlight uses a single phase 480 volt system (which 95% our streetlights are), No Neutral. There are two lines (two black wires each with 240 volt to ground) Obviously you can't have a white wire which is the NEC standard color for a Neutral, which is a non-current carrying conductor, used as a current carrying conductor with 240 volts. Hand hole and grounding detail (Sheet G-1, NTS 5) continued : "480V POLE HAND HOLE AND GROUNDING DETAIL" : In your notes within the box I see you are trying to cover all voltage scenarios. For this installation both wires are "240 volts #12 black-THW / XHHW". You can add note here both wires are black in color and carrying 240 volts each for single phase 480 volt systems. The representation of the wire nut can be eliminated in your hand hole drawing since a continuous run is preferred. The fuse holders shall be in the City pull box (J Box) to the fixture, not spliced at the hand hole. Normally the City uses continuous run of #10 THW, but #12 is acceptable from pull box to fixture. Also at the hand hole drawing, Change text "#8 Cu FROM GROUND GREEN - THW / XHHW - FROM JUNCTION BOX" to read ( #8 BARE CU FROM POLE GROUND buss TO CITY J-BOX ) This will be our bond wire which connects to all the metal poles and goes back to the grounding lug at the City load center. Note: The City of Tucson Roadway Lighting Systems don't use a green ground/bond wire. We use a #8 BARE SOLID COPPER BOND for the grounding/bonding system within the circuit conduits and to any grounded equipment or ground buss. The only place you might see a green ground is in the luminaire or maybe some small equipment at the load center. (note the #4 bare Cu wire from foundation to pole ground bolt at hand hole or ground buss is correct!) |
