Precision in Every Turn: The NS Controls Torquing Standard

At NS Controls, we take precision seriously, and proper torquing is a key part of our integration process. Our procedure ensures that all hardware connections meet our quality and safety standards for MCC panels, MV gear, and other electrical enclosures.

NS Controls’ Torquing Procedure

Our team follows a structured torquing process to ensure consistency and compliance with project specifications.

1. Verify Bolt Size and Torque Specification

Before beginning, our team:

• Identifies the bolt or nut size and type.

• Retrieves the appropriate torque setting from the Torque Signoff Sheet

• Checks out the correct torque wrench and necessary attachments from the tool room.

• Uses a torque multiplier wrench for torque values exceeding 600 ft/lbs.

  
  

2. Torquing Process

At NS Controls, we follow the principle that “it takes two to torque”—one technician operates the torque wrench while another verifies and signs off.

Once the correct specifications and tools are in place, our technicians:

• Set the torque wrench to the required torque value.

• Secure the correct attachment and place it on the hardware.

• Apply consistent pressure until the torque wrench clicks (or, for digital wrenches, until a solid tone and green light indicators confirm proper torque).

• Sign off each completed torque point on the Torque Signoff Sheet to document compliance.

  
  

For lifting eyes:

• On racks, bolted lifting eyes are torqued and painted before integration whenever possible.

• On buildings, lifting eyes are torqued after all work is completed and verified by the Production Manager or Quality Coordinator.

  
  

3. Marking and Documentation

After torquing, all completed connections are clearly marked:

• Torque paint is applied where possible so that anyone can easily verify completion.

• If torque paint is not feasible, a “Torqued by NS Controls” sticker is placed near the torqued bolt.

• Black Sharpie markings are used to ensure visibility.

• Torque sheets are provided to the customer upon request as part of our documentation process.

  
  

4. Special Considerations for Transformers & Buss Connections

For transformers using Grade 5 hardware:

• Electrical Technicians wire the transformer per manufacturer’s instructions.

• A Project Manager or Quality Coordinator verifies the connections before torquing.

• Torque is applied as per the Torque Signoff Sheet, followed by splice taping where required.

• A “Torqued by NS Controls” sticker is applied to indicate completion.

  
  

For buss connections:

• Electrical Technicians assemble sections per the design specifications.

• Buss connections are torqued according to the manufacturer’s torque settings.

• The Quality Coordinator, Production Manager, or Design Team member witnesses the torquing process and applies the necessary markings.

• In some cases, customers prefer to witness the torquing process themselves. We welcome this and allow them to act as the official witness and sign off on the torque sheet.

  
  

5. Final Review

Once torquing is complete:

• A final review is conducted to ensure all required markings, sign-offs, and documentation are in place.

  
  

At NS Controls, proper torquing is an essential part of delivering high-quality, reliable electrical integration solutions. By following our structured process, we ensure each project meets our high standards for safety and performance.
