5.0.        Installation Procedure

5.1.  Site Preparation

5.1.1. Ensure that all necessary permits and approvals have been obtained for the installation.

5.1.2. Identify the routing for the conduit, ensuring compliance with electrical design drawings and safety regulations.

5.1.3. Clear the surface area of any obstructions, debris, or obstacles that may hinder the installation process.

5.1.4. Identify and mark the locations for conduit supports and anchors at regular intervals along the intended route. These should be spaced as per industry standards and project specifications.

5.1.5. Verify that the surface where the conduit will be mounted is level and properly prepared for attachment.

5.2.  Installation of G.I. Conduit

5.2.1. Measure and cut G.I. conduit pipes to the required lengths using a hacksaw or pipe cutter.

5.2.2. Use pipe benders to shape conduit, if necessary, to accommodate bends as per the design.

5.2.3. Secure conduit straps and clamps to the wall or ceiling using appropriate anchors and screws.

5.2.4. Mount the G.I. conduit pipes onto the straps and clamps, ensuring they are level and aligned with the marked route.

5.2.5. Secure conduit fittings (elbows, couplings, connectors, etc.) as needed, using appropriate techniques and fittings.

5.2.6. Ensure all conduit joints are properly threaded and sealed with suitable thread sealant.

5.3.  Installation of PVC Conduit

5.3.1. Use a pipe cutter to Measure and cut PVC conduit pipes to the required lengths.

5.3.2. Dry-fit the PVC conduit pieces to ensure proper alignment and fit.

5.3.3. Clean the ends of the PVC conduit and apply PVC solvent cement as per the manufacturer's instructions.

5.3.4.Assemble and secure the PVC conduit sections together, ensuring a watertight and secure connection.

5.3.5. Mount PVC conduit onto the wall or ceiling using appropriate straps and clamps.

5.3.6. Ensure that the PVC conduit is level and aligned with the marked route.

5.4.  Cable Pulling

5.4.1. Lubricate the inside of the conduit using cable lubricant.

5.4.2. Pull electrical cables through the conduit, ensuring they are not strained or damaged during the process.

5.4.3. Ensure proper separation between different types of cables, as per electrical codes and design specifications.

5.5.  Final Checks

5.5.1. Conduct visual inspections to verify that all conduits and fittings are securely installed and aligned.

5.5.2. Ensure that all electrical cables are properly routed and secured within the conduit.

5.5.3. Label the conduit as necessary, indicating the cables' type and conduit functions.

5.5.4.Test5.5.4. Test the conduit system for any obstructions or defects by pulling a cable through it.

6.0.        Safety Precautions

6.1.1. Always wear appropriate personal protective equipment (PPE) while performing installation work.

6.1.2. Be cautious of sharp edges and hot surfaces when working with conduit materials.

6.1.3. Follow all electrical safety procedures when handling live electrical cables.

6.1.4. Use proper lifting techniques when handling heavy conduit pipes and materials.

6.1.5. Keep the work area clean and organized to prevent accidents.

7.0.        Quality Control

7.1.1. Ensure that all conduits and fittings are installed according to the manufacturer's recommendations and industry standards.

7.1.2. Conduct inspections and tests to verify the integrity of the conduit system and cable installations.

7.1.3. Address any non-conformities or defects promptly and make necessary corrections.
