Killark OTB-1 TB Type Conduit Body Instruction Manual

1. Introduction

This manual provides essential information for the safe and effective installation, function, and maintenance of the Killark OTB-1 TB Type Conduit Body. The Killark OTB-1 is an aluminium electrical fitting designed for use in conduit systems to protect electrical conductors, provide access for wire pulling, splicing, and to change direction of conduit runs.

Please read this manual thoroughly before proceeding with any installation or maintenance procedures.

2. Safety Precautions

• Always disconnect power to the electrical circuit before installing, servicing, or inspecting the conduit body.
• Ensure all installations comply with national and local electrical codes and regulations.
• Use appropriate personal protective equipment (PPE) during installation.
• Do not modify the conduit body. Use only as intended.
• Ensure all connections are secure and properly sealed to prevent moisture and dust ingress.

3. Installation

The Killark OTB-1 TB Type Conduit Body is designed for straightforward installation in rigid or IMC conduit systems. It features a 1/2 inch hub size.

3.1 Components

The conduit body typically consists of the main housing and a removable cover (not explicitly shown but implied for access).

3.2 Installation Steps

1. Preparation: Ensure the conduit ends are clean, free of burrs, and properly threaded.
2. Mounting: Securely mount the conduit body to a suitable surface or structure using appropriate fasteners. Ensure it is stable and can support the weight of the conduit and wires.
3. Conduit Connection: Thread the conduits into the hubs of the conduit body. Tighten connections firmly to ensure electrical continuity and mechanical strength.
4. Wire Pulling/Splicing: Once conduits are connected, wires can be pulled through or spliced within the conduit body's accessible interior.
5. Sealing: After wire installation, ensure the cover (if applicable) is securely fastened and any necessary gaskets or sealing compounds are properly applied to maintain environmental integrity.

4. Function

The Killark OTB-1 TB Type Conduit Body serves several critical functions within an electrical conduit system:

• Wire Protection: It provides a protective enclosure for electrical conductors, shielding them from physical damage and environmental elements.
• Access Point: The removable cover allows for easy access to conductors for pulling, splicing, and maintenance without having to dismantle the entire conduit run.
• Direction Change: The 'TB' type configuration allows for a 90-degree change in conduit direction, with an additional hub for a straight run, facilitating complex wiring layouts.
• Conductor Management: It provides space for making splices, taps, or for managing excess wire length at junction points.

5. Maintenance

Regular inspection and maintenance ensure the longevity and safe operation of the Killark OTB-1 TB Type Conduit Body.

• Visual Inspection: Periodically inspect the conduit body for any signs of physical damage, corrosion, or wear.
• Connection Integrity: Check that all conduit connections are tight and secure. Loose connections can lead to electrical issues or compromise environmental sealing.
• Sealing: Verify that the cover (if present) is properly sealed and that any gaskets are intact and providing an effective barrier against moisture and dust. Replace damaged gaskets as needed.
• Cleaning: If necessary, clean the exterior of the conduit body with a damp cloth. Avoid abrasive cleaners that could damage the finish.

6. Troubleshooting

While the Killark OTB-1 is a passive component, certain issues may arise that require attention.

• Issue: Loose Conduit Connection.
  Solution: Disconnect power, then re-tighten the conduit into the hub. Ensure threads are clean and undamaged.
• Issue: Water or Dust Ingress.
  Solution: Disconnect power, inspect the cover and gasket for damage. Replace damaged gaskets or covers. Ensure the cover is securely fastened. Apply appropriate sealing compound if necessary.
• Issue: Physical Damage (e.g., cracks, dents).
  Solution: If the conduit body is significantly damaged, it may compromise its protective function and structural integrity. Disconnect power and replace the damaged conduit body immediately.
• Issue: Corrosion.
  Solution: Minor surface corrosion on aluminium can sometimes be cleaned. However, if corrosion is extensive and compromises the material's integrity or sealing, the conduit body should be replaced.
