2.
Electrical Cable Installation During the reporting period, the inspector observed work including a.
installation, handling, and protection of electrical cables. Speci-fically, work associated with these electrical cable pulls was observed:
(1) Cable Pull 263 Cables 4GNK03BA 4ENG02bc 4ENG02BD 4EJG09AC 4EJG09BC (2) Cable Pull 650 Cable 1SAZO2LC b.
For each of the pulls some or all of the following activities were observed:
(1) Pull cards were in use, (2) the cables were identified, (3) Quality Control inspections were performed and Quality Control personnel witnessed the pull.
On one occasion it was noted that Electrical Craftsmen were stepping on previously pulled cable. This condition was brought to the attention of the Licensee. Action was taken in training sessions to re-emphasize to Electrical Craftsmen that installed cable must be protected from work activities.
g, The method of supporting electrical cables in vertically
,
' mounted raceways was reviewed. Presently the cables are tied
j in place and supported by plastic tie wraps around tray rungs.
Bechtel Drawing No. E0103Q (paragre.ph 5.3.9.2) discusses cable i
support in vertical cable trays and states that cables may be supported from building steel using Kellum gripes or from tray rungs. The drawing also refers to IEEE std. 422 paragraph 7.2.5 which states that vertically run cables be supported by holding devices in tray and be lashed or served at support points co keep the cable within the side rails. The Siesmic qualification data for plastic tie wraps is not available for review. Pending review of this data along with any installation instructions such as the number and type of cable allowed to be tied by a signie wrap, will be nn unresolved item.
