Some submittals are already marked with a “G”. Only delete an existing “G” if the submittal item is not complex and can be revie
14、wed through the Contractors Quality Control system. Only add a “G” if the submittal is sufficiently important or complex in context of the project.For submittals requiring Government approval on Army projects, a code of up to three characters within the submittal tags may be used following the “G“ d
15、esignation to indicate the approving authority. Codes for Army projects using the Resident Management System (RMS) are: “AE“ for Architect-Engineer; “DO“ for District Office (Engineering Division or other organization in the District Office); “AO“ for Area Office; “RO“ for Resident Office; and “PO“
16、for Project Office.

The installation of cutouts rated at 7.8 kV on these systems is not allowed.Provide fuse links with a continuous rating equal to approximately 150 percent of
27、 the full-load line current when used for transformer protection, and approximately 100110_ percent of the conductor rated capacity when used for circuit protection. Ensure the 15-kV cutout has a wet withstand, 10-second voltage rating of 37 kV, with a 95-kV basic impulse level (BIL). Provide with a
28、 continuous current rating of 100 amperes unless otherwise indicated. Provide fuse disconnects rated not less than 100 amperes, having attachments to permit manual operation of the disconnect under load without external arcing.Where indicated,combine lightning arresters and fuse cutouts.PART 3 EXECUTION3.1 INSTALLATIONInstall distribution fuse cutouts in accordance installation drawings with the manufacturers installation instructions.- End of Section -SECTION 33 77 36.00 40 Page 6Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-
