TORQUE AND SCREW SIZING
The following table shows, broadly speaking, the recommended torque for both mechanical and electrical
connections, applicable to all cabinets.
[a] For other qualities, follow the screw’s manufacturer guidelines.
For all screwing that holds a particular component such as a bus, contactor, etc. it will be necessary to
apply the tightening torque indicated by the manufacturer of the same component
Screwing should be tightened correctly only when necessary, i.e. when the factory marks are not in place.
For small screws that do not have marks, the good electrical praxis will determine if it is loose.
