Check The Tightness Of The Grooved Wire Clamp Nut.

Visually inspect the contact between pg clamps and the conductor, recording the position and condition of all nuts, checking for any obvious signs of loosening, corrosion, or deformation. The upper and lower housings of single bolt parallel groove connector should be on the same mounting surface. If relative tilting is found, readjust their positions; this is fundamental to ensuring the conductor's contact surface with the groove is aligned.

For nuts found to be slightly loose during inspection, readjust them point by point to the specified torque value, maintaining a balanced force on all fasteners.
