Sujal Jwarchan

Apartment unit and Residental Rough in-fit out and Industrial

-Interpreted and marked out wiring layouts for power, lighting, and Telecommunication circuits using floor plans

-Ran cabling in Loop at light and loop at the switch

-Fitted off GPOs, smoke detectors, led strip lights, oyster lights, socket outlets, fans, cat 6 keystone jacks, hot water systems ,intermediate switches, etc

-Added speaker systems, cameras, to pre existing spaces

- Mounted and fitted off highbays, floodlights, spitfires, 3 phase socket outlets, Dbs, Comms rack, etc

Deckwork / Groundwork

-Interpreted plans and marked deck for feeds, exit signs, lights, powerpoints, wall lights, roller doors, lifts, pumps, etc and connected with conduits and junction boxes

-Set up 3 phase Temporary boards on the deck

-Marked paths for underground submains and ran conduits

-In charge of spotting various eqiupment to dig treches

Construction of Cable Support System

- Planned the most efficient path for the cable tray

- Fabricated UT3, UT5 ,perforated tray and cable mesh to make turns and bends while being mechanically strong

- Built cable tray supported by uni-strut suspended overhead leading from Main switchboard room to desired locations i.e. building electrical risers and using various different support methods such as various angled post brackets and threaded rods horizontally to set up vertical cable trays whilst keeping them mechanically strong

Submains

-Mounted Distribution boards, Meter panels and link boxes

-Connected unit mains and 3-phase power supply on the Meterpanels

- ConnectedMeter panel supply to rat fuses in Linkboxes

-Connected lighting, power circuits and Emergency lighting test switch in Distribution Boards - Ran 3-Phase cables to building services (elevators, stormwater pumps, sewage pumps, mechanical boards, Linkboxes, etc)

-Connected generators to supply hoists and cranes for temporary power

- Connected rainwater pumps in the control board

Main Switch Board

-Joined together MSBs weighing over 2t using rollers, a jack, forklift and crowbar making sure we are precise to mm as the internal copper bars need to be aligned to connect the MSB internally

- Connected Main power supply, Submain supplies, and essential and non-essential services such as lifts cables ( Aluminium and copper) to various breakers ( RCD, MCCB, ACB) with capacities up to 600A -Used Hydraulic Crimpers to crimp copper, Bi-metal Aluminium lugs and Bi-metal Reducing links up to 300mm.

- Modified copper bars in MSB to allow Bi-Metal and copper lugs to fit by adding offset copper bars or drilling a 10mm hole for the lugs

-Measured, marked and drilled holes on Bakelite (top of the board) for glands to allow cables through in the most efficient spot to their connection

- Connected 10 core cables in the CT Chambers and Testblocks

Fire systems

-Interpretted wiring diagrams and floor plans to run radox cable

-Mounted and fitted off smoke alarms, speaker system, lifting magnets, strobe lights

Testing

-Tested Insulation Resistance, Shorcuits, Polarity and Phase rotation for Main Power supply and sub-mains supplies Permanent or Temporary ( hoists, Link box feeds, cranes, etc) RCD testers on temp boards
