Standard Operating Procedure for electrical conduit installation ensuring safety, compliance with regulations, and quality workmanship for residential, commercial, and industrial buildings.
To establish a safe and standardized method for electrical conduit installation in buildings, ensuring compliance with IS codes and industry best practices for optimal electrical infrastructure.
This SOP applies to all types of electrical conduit installations including:
Ensures adherence to drawings and safety standards
Installs conduits and wiring as per specifications
Monitors PPE usage and safety compliance
Coordinates with electrical team to prevent structural damage
Ensures installations meet project specifications
Coordinates timing of electrical work with construction phases
PVC, HDPE, or GI conduits with ISI marking (IS 9537:2003)
Appropriately sized PVC or metal boxes for connections
IS-marked copper wires with appropriate gauge
Measuring tape, level, marking chalk
Drill machine, pipe cutter, bending spring, hacksaw
Fish tape, wire pulling lubricant

Use insulated tools, wear PPE (gloves, goggles, safety shoes)
Ensure power is OFF during work, use voltage testers to confirm
Avoid sharp bends, maintain minimum bending radius (2.5× diameter)
Use proper tools for cutting/drilling, secure power tools properly
Keep first aid kit accessible, know emergency contact numbers
Have appropriate fire extinguishers nearby, know evacuation routes
Use IP-rated equipment, maintain minimum 60cm distance from water sources
Separate data conduits from power by minimum 300mm, use metal barriers when crossing
Provide flexible connections when crossing building expansion joints
Use UV-resistant conduits, provide drainage points to prevent water accumulation
Use pulling lubricant, check for obstructions, avoid exceeding 40% fill ratio
Use cable tracer, implement systematic labeling from the start
Improve sealing, use waterproof junction boxes, install drain points
Check terminal connections, ensure proper stripping of wires, verify continuity
Proper electrical conduiting is fundamental to building safety and operational efficiency. Following this SOP ensures that conduit installations meet regulatory requirements and industry best practices. By adhering to these guidelines, electrical systems will be safe, reliable, and maintainable throughout the building's lifecycle.
