ELECTRIC WORK ITEMS GENERAL: A) ELECTRIC FEEDER TO BE RELOCATED TO SUPPORT ROOF ELECTRIC FEEDER TO BE RELOCATED TO SUPPORT ROOF REPLACEMENT. CONTRACTOR SHALL REMOVE AND REPLACE A 500AMP FEEDER IN DIFFERENT LOCATION TO SUPPORT THE THICKER EXPECTED ROOF AND ROOF INSULATION. DUE TO ROOF AND INSULATION GROWING IN THICKNESS THE FEEDERS WILL NEED TO BE RAISED ABOVE THE ROOF. B) THE CONTRACTOR SHALL STOP WORK IF ANY DIFFERENCES IN THE CONTRACTOR SHALL STOP WORK IF ANY DIFFERENCES IN THE EXISTING WIRING THAT DIFFER FROM WHAT IS DESCRIBED IN THESES GENERAL OR SPECIFIC WORK ITEMS. CONTRACTOR SHALL SUBMIT AN RFI IMMEDIATELY AND IN SUFFICIENT TIME TO THE ATTENTION OF THE ENGINEER. IN THE RFI THE CONTRACTOR SHALL DESCRIBE THE SPECIFIC ISSUE AND ANY PROPOSED SOLUTIONS THAT THEY MAY HAVE TO CORRECT ISSUES. C) IT IS PROPOSED TO SAVE THE MAJORITY OF CONDUCTORS AND IT IS PROPOSED TO SAVE THE MAJORITY OF CONDUCTORS AND REPLACE THE EXISTING CONDUIT AND JUNCTION BOX ON THE ROOF. THE EXISTING CONDUITS AND CONDUCTORS ARE BELIEVED TO BE A PARALLEL SET OF CONDUCTORS FOR A 500AMP FEEDER. CONTRACTOR SHALL VERIFY AT START OF THE PROJECT IF THIS IS THE CASE. D) ADDITIONAL CONDUCTOR LENGTH AND SPLICING WILL BE ADDITIONAL CONDUCTOR LENGTH AND SPLICING WILL BE REQUIRED. SINCE THE TWO SETS OF CONDUIT AND CONDUCTORS ARE POSSIBLY IN PARALLEL THE EXTENDING OF CONDUIT AND CONDUCTORS SHALL BEEN DONE IN A MANNER TO MAINTAIN CONDUCTOR LENGTHS AND TYPE THAT ARE EQUAL AND SIMILAR ELECTRICALLY. THE WIRING SHALL MEET THE NATIONAL ELECTRIC CODE ARTICLE 310.10(H) CONDUCTORS IN PARALLEL. E) ALL JUNCTION BOXES SHALL BE SIZED TO NATIONAL ELECTRIC ALL JUNCTION BOXES SHALL BE SIZED TO NATIONAL ELECTRIC CODE ARTICLE 314.28 PULL AND JUNCTION BOXES. ALL JUNCTION BOXES SHALL BE ENCLOSED AND GASKETED. ALL CONDUIT CONNECTIONS TO JUNCTION BOXES SHALL USE WATER PROOF HUBS OR DIRECT CONDUIT CONNECTIONS WITH SEALS. F) IT IS PROPOSED TO PULL THE CONDUCTORS BACK TO THE IT IS PROPOSED TO PULL THE CONDUCTORS BACK TO THE POINT BELOW THE SWEEPS DESCRIBED IN WORK ITEM 3 BELOW BY DISCONNECTING THEM FROM THERE BREAKER FEED AND PULLING THEM BACK, AND REINSTALLING THEM IN THE RELOCATED CONDUITS TO THE JUNCTION BOX ABOVE THE ELECTRIC ROOM. THIS REQUIRES THE CONTRACTOR TO UNSCREW OR CUT CONDUITS OFF WITHOUT DAMAGING THE EXISTING CONDUCTORS. THE ADDITIONAL CONDUCTOR LENGTH NEED CAN BE SPLICED IN TO MAKE THE 25' DROP TO THE ELECTRIC GEAR. ALL SPLICES SHALL BE MADE IN A SPLICE OR JUNCTION BOX. THERE SHALL NOT BE ANY SPLICES IN ANY CONDUIT. ELECTRIC WORK ITEMS NUMBERED 1) TWO HORIZONTAL CONDUITS WITH CONDUCTORS WILL NEED TO TWO HORIZONTAL CONDUITS WITH CONDUCTORS WILL NEED TO BE REMOVED AND REPLACED FROM THE JUNCTION BOX ALL THE WAY TO VERTICAL WALL SECTION INCLUDING THE (2) 90-DEGREE SWEEPS TO THE VERTICAL SECTION RUNNING DOWN THE WALL ON THE OTHER END OF THE ROOF. REPLACEMENT CONDUITS SHALL BE SAME SIZE OR LARGER. IF EXISTING CONDUIT ARE REUSED THE CONTRACTOR SHALL TAKE ALL RESPONSIBILITY WITH THE INSTALLATION AS NEW. CONTRACTOR SHALL PROVIDE CONDUITS SUPPORTS COMPATIBLE WITH THE REPLACEMENT ROOF. ALL CONDUIT SPORTS SHALL BE NEW. 2) THE JUNCTION BOX IS TO BE REPLACED WITH JUNCTION BOX THE JUNCTION BOX IS TO BE REPLACED WITH JUNCTION BOX THAT IS LARGER IN SIZE TO ACCOMMODATE SPLICING AND EXTENSION OF THE EXISTING CONDUCTORS. 3) THE TWO 90 DEGREE SWEEPS FROM VERTICAL SECTION TO THE TWO 90 DEGREE SWEEPS FROM VERTICAL SECTION TO THE ROOF SHALL BE REPLACED WITH A JUNCTION /PULL BOX THAT MOUNTS OFF THE BUILDING AND EXTENDS ABOVE THE ROOF, LB'S WITH VERTICAL CONDUIT EXTENSIONS CAN ALSO BE USED FOR THIS SECTION.
