2 SUMMARY The Adhunik Poshak Shilpa Ltd. factory is in a twenty storied building. The building was constructed in The factory started production in The building was approved for industrial purposes, and during the survey the factory had about 2,285 workers working on regular basis. The Factory was surveyed for electrical safety by Woosun Energy and Construction Co., Ltd. (WEC). The purpose of the survey was to identify significant electrical safety issues and to provide recommendations for remediation based on applicable standards specified by the Accord. The scope of this initial electrical safety inspection was limited to the review and identification of major electrical safety issues. The inspection did not include identification of minor deficiencies, which will be further addressed as part of follow-up inspections. Table below summarizes the major electrical safety issues identified during the inspection. Recommendations have been provided to address each issue. An implementation schedule shall be developed by the factory to remediate each of the findings. The specific timing of improvements, including any requested extensions due to design / installation constraints, shall be submitted to the Accord for approval. Adhunik Poshak Shilpa Ltd.

3 FINDINGS AND RECOMMENDATION Finding No. E- 1 Category: SERVICE LINE HT cable laid on floor without protection. Construct a cable trench to route the HT cable safely inside the substation room or install cabletray or duct to provide mechanical protection to the cable to prevent any physical damage to cable. HT cable inside the basement. Finding No. E- 2 Category: SERVICE LINE HT cable entering panel touching sharp steel edges of the enclosures and laid on concrete floor. Cables must be protected from possible damage of cable-insulation due to panel edges or sharp objects and Install a cable ladder to terminate the excessive cables and fasten the cables with the ladder so that the cables get fixed with the ladder firmly. Ensure the cables are free from dust and debris. HT cables passing through wall and underground. Adhunik Poshak Shilpa Ltd. Page 3 of 8

4 Finding No. E- 3 Category: SERVICE LINE HT cable passing through the wall/floor without support and protection. HT cables entering the ceiling/wall left. must protect with mechanical structure around the cables to prevent it from physical damaging. HT cable inside the basement. Finding No. E- 4 Multiple cables/wires connected at a terminal of the HRC fuse. Multiple cable/wires terminating at a terminal in single point must be avoided to prevent heat generation at terminal. Cables connecting to HRC fuse inside LT panel. Finding No. E- 5 Multiple cables terminating to contactor without lugs inside the panel. Multiple cables connecting to MCCB terminal must be avoided. Individual protective device must be provided for the protection of each circuit/load. Cables shall be connected to terminals only by soldered/welded lugs according to cable size. Cable connecting to contactor. Adhunik Poshak Shilpa Ltd. Page 4 of 8

5 Finding No. E- 6 Panel doors not connected with earth bond. Provide earth connection for body and doors of metallic distribution boards using green cables preferably braid so that the metallic door remains at zero potential all the time. Control panel for Diesel generator. Finding No. E- 7 - Multiple cables connected to single terminal at the changeover switch. Multiple cables shall not be connected to a single terminal to avert loose connection that may induce unexpected heat and it may be replaced with single core cable with bigger size of current carrying capacity or separate bus bar for multiple cable termination. Manual changeover switch. Adhunik Poshak Shilpa Ltd. Page 5 of 8

6 Finding No. E- 8 Excessive wires crowded inside the panel. Wires terminating to devices inside panel must be connected firmly and wires approaching devices must be securely fastened to avoid unintentional contact with live parts. Install PVC slotted wiring duct to latch the excessive cable inside the duct. Control panel for motors. Finding No. E- 9 Excessive bent in cable and Cable inside panel touching bare bus bar. Sharp cable bends shall be avoided such that no stress is imposed on the termination of the cable or insulation of the cable. Cables terminating in the panel must not contact/touch the bare bus bar. Install slotted wiring-duct inside the panel to arrange and latch the haphazard cables. Cables inside DB-A/L-3 (typical). Adhunik Poshak Shilpa Ltd. Page 6 of 8

7 Finding No. E- 10 Category: CABLE & CABLE SUPPORTS Cables are supported with PVC pipe which is partially exposed and dust deposited. The PVC/rigid pipe used for surface wiring must be continuous through-out its length and properly supported (clamped with saddle, at regular interval of 600 mm).the conduit shall not be open at any instant and it should be fully protected through its length to prevent ingress of dust inside. PVC conduit fills with dust. Finding No. E- 11 Category: WIRINGS Wires exposed while transiting between different wiring systems (e.g., Casing capping to PVC conduit) Provide PVC pipe to support and protect the cables throughout its length. Wiring exposed between different wiring systems may be prevented by selecting appropriate adapter to connect two wiring system. Wiring inside production floor. Adhunik Poshak Shilpa Ltd. Page 7 of 8

8 Finding No. E- 12 Panel base plates removed to allow cable entry. Make circular hole at the base plate/top plate of panels and provide cable gland according to the respective cable size for cable entry and exit so that the cables are not stressed on the sharp edges of the hole of panels. Provide covers (of noncombustible material) if any additional gap remains after installing cable glands. Cable connecting to the MCCB inside LT panel. Adhunik Poshak Shilpa Ltd. Page 8 of 8
