Electrical SOW:
1. All panels and subpanels to be 16 SWG and complying to IP65 protection.
2. For Elevated Towers Panels will be installed beneath the tower and for Guard booths these will
be installed adjacent to the post.
3. All Elevated towers and Guard Booths (post) to be provided with separate subpanels. Please
follow details and illustrations provided in Appendix “A”.
4. All subpanels as mentioned in para 1 will be connected to the main panels designated by
Security Gates. A Total of six main panels are required to supply power to elevated towers and
guard booth subpanels. Please follow Appendix “A” for details.
5. All Power distribution from main to the subpanels and inside the posts shall be in water tight
fitting.
6. All underground conduits to be good quality UPVC Schedule 40. G.I conduits will be used for
road crossing and concrete areas. These UPVC and G.I Conduits to buried at a minimum depth of
1feet below finished grade.
7. Where possible conduits will be run on the wall to avoid road cutting, however anything conduit
or other accessories above the ground to the G.I type with proper support.
8. All conduits to be sized in such a way that about 50% space is left after the required cable has
been pulled.
9. Install pull wires in empty raceways. Use polypropylene or monofilament plastic line with not
less than 90-kg tensile strength. Leave at least 300 mm of slack at each end of pull wire.
10. All towers and booths to be provided with lightning protection and ground pits. Follow drawing
QE-USK-14-AB-GTE16-Model for grounding and lighting protection details.
11. For Electrical lights and other accessories requirement follow drawing 23.
12. Power distribution inside each post will be through 1” G.I conduit and switches/receptacles will
be installed on metallic junction boxes. The power distribution as a whole will be bonded up to
the main panel. Junction boxes will be properly grounded. All receptacles to be three pin type.
For Phase, neutral and ground.
13. Install wire and cable with sufficient slack and flexible connections to allow for vibration of piping and equipment. Conductors at each outlet should have at least 200 mm of slack.
14. Locate pull /floor boxes at every 100 feet intervals and other 90-degree bend. All pull/ floor boxes to be water tight to prevent rain water entering into it.
15. Perform the following field tests and inspections and prepare test reports: After installing wiring devices and after electrical circuitry has been energized, test for Proper polarity and ground continuity. Test and verify GFCI operation. Measure all cables insulation resistance.
16. Remove malfunctioning units, replace with new units, and retest as specified above.
