What is the expected torque (pound-feet) value of a 3/8" Grade 5 bolt on new switchgear bus?

The expected torque value for a 3/8" Grade 5 bolt on new switchgear bus is typically around 15 pound-feet. This value is derived from torque specifications that ensure adequate clamping force while preventing bolt failure, as well as considerations for the material being fastened.

In the context of electrical installations, such as switchgear, proper torque settings are essential to ensure electrical connections are secure and to prevent issues such as overheating or connection failure during operations. Each grade of bolt has specific torque requirements due to its tensile strength and material properties, with Grade 5 being a common choice for general applications.

Understanding the proper torque for bolting applications is critical for safety and reliability. Therefore, using 15 pound-feet ensures that the connection is tight enough to handle operational stresses while adhering to best practices for installation.
