DON NELLY ENGINEERING ELECTRICAL of the conduit penetrations consisting of gland type sealing bushing or closed cell silicone foam. Provide duct seal inside an appropriate seal-off fitting to seal the interior of the conduit system from water seepage or hazardous gases. D. Routing: Conduits shall be run parallel to building walls wherever possible, exposed or concealed as specified, and shall be grouped in workmanlike fashion. Crisscrossing of conduits shall be minimized. E. Location: All raceways shall be run concealed from view. Surface mounted devices and equipment shall be specifically noted on the contract drawings or shall be located where panelboards are surface mounted. It is the intent that all raceways shall be run concealed unless specifically noted. F. Protection: All raceway runs, whether terminated in boxes or not, shall be capped during the course of construction until wires are pulled in and covers are in place. No conductors shall be pulled into raceways until the raceway system is complete. G. Coordination: All raceways shall be kept clear of mechanical equipment and plumbing fixtures to facilitate future repair or replacement of said fixtures without disturbing wiring. Except where it is necessary for control purposes, all raceways shall be kept away from items producing heat. H. Masonry Installation: All raceway runs in masonry shall be installed at the same time as the masonry so that no face cutting is required, except to accommodate boxes. I. Arrangement: All raceways shall be run connecting outlet to circuits generally as shown on the drawings. Provide circuit connection arrangement shown. Actual final arrangement shall be in accordance with the record drawings section as specified herein. J. Grounding: All branch circuit and feeder raceways shall have a insulated copper system ground conductor within the conduit throughout the entire length of the circuit. All conduit shall be electrically continuous to establish redundant grounding. 1. Branch circuit raceways shall have an insulated equipment grounding conductor installed within the conduit raceway system. 2. Grounding conductor shall be included in total conduit fill determining conduit sizes, even though not shown on drawings. 3. Grounding conductors run with feeders shall be green insulated only. 4. Grounding conductors run with normal and essential electrical system feeders serving patient care area shall be bonded to portions of conduit that are metal by listed grounding bushings. K. Empty Raceways: Raceways which do not have conductors provided under this Division of the specifications shall be left with an acceptable nylon pullcord in raceway. L. Manufacturer: Rigid Metallic Conduit, Electrical Metallic Tubing, Flexible Steel Conduit, Liquid-Tight Flexible Conduit, and PVC Conduit shall be manufactured within the United States, and each shall be as manufactured by one manufacturer. M. Roof Installation: Conduit installations on roofs shall be exposed to a bare minimum. Conduit shall not be installed on roofs. Metal conduit stubs to mechanical equipment or receptacles are allowed however they must connect directly to the equipment or device without resting or supported on the roof. N. Firewall Installation: Provide pullboxes, junction boxes, fire barrier at fire rated walls etc., as required by NEC Article 300 where required. O. Dissimilar Metals: Avoid the use of dissimilar metals to reduce the possibility of electrolysis. Where dissimilar metals are in contact, coat all surfaces with corrosion inhibiting compound before assembling. P. Sealoff Fittings: Provide conduit sealoffs wherever the raceway system enters a hazardous or wet area'or areas of drastic temperature change such as coolers, freezers, etc. as required.
