Refer to Table 2 above.
Conduit identification shall be verified by the QC Inspector to comply with the latest approved drawing requirements at drawing changes / revisions are released which change a condui t's identification after QC acceptance of the conduit, the following actions shall be taken:
- a. Changes to " Raceway Function", " Train / Channel Designation" or " Unique Number" shall require rework to reidentify the conduit and QC verification of proper identification. An IR, Attachment 2, shall be initiated to ' document the above verification. All Inspection attributes except "Ve rify Conduit Identification" shall be noted "N/A" and the drawing nunber and revision or DCA nunber that authorized the change shall be recorded in the " Remarks" section. The previous conduit identification shall also be referenced in the
" Remarks" section.
- b. Changes to the " Unit Designation" shall not require reidenti-fication and reinspection of the affected conduits. The Interim Vault shall prepare a Pennanent Plant Records Vault Transmittal, to document these conditions and provide a cross reference record. The transmittals shall be sent to the Pennanent Plant Records Vault for filing with the respective conduit records.

- QI-QP-11.10-1A Rev. 1 Page 19 of 37 SEP 21 19A4
- a. Recommended Method - Paint exposed conduits with a full 360*
band at intervals not to exceed 15 feet and at points of entry to and exit from enclosed areas and on both sides of floor and wall penetrations. Paint color shall match as close as possible the appropriate cable jacket color of the safety related cables to be installed in a conduit. Paint band shall be at least one inch wide and shall be readily visible from floor level. It is recognized that for conduits in-stalled against walls and floors, it may be impossible to obtain a full 360' band for color coding requirements. In these cases, the maximum band possible shall be made,
- b. Alternative Method - Use color coded adhesive markers with similar requirements as to color, width or marker.
Adhesive marking labels shall not be used inside containment or in manholes.
3.7.6 Verify Junction and Pull Box Size and Type Unless shown otherwise on material lists or drawings, junction boxes shall be type NEMA 12 enclosure (minimum).
Where the installation and corresponding drawing requires a Nema 4 junction box the QC Inspector shall verify that the junction box is a Nema 4.
The QC Inspector shall verify that rubber gaskets have been in-stalled on the mounting hardware (interior and exterior) and is of the type and size as specified on the drawing, Reference 1-N and 1-0.
Electrical " pull boxes" which are unscheduled on the Engineering drawings, may be installed to minimize conduit installation
. problems.
Where junction boxes are provided solely as cable pulling points in the conduit system and where space or support considerations make junction box installation impractical, pull box fittings, OZ/Gedney type "PBW" or approved equal, may be substituted for the junction box shown on the drawing.
Where junction boxes are used as terminal boxes the inspector shall visually inspect for those attributes previously stated herein for boxes and, in addition, verify the mounting hardware 1 for the tenninal block installed, j l
