Terminal Blocks
H- or P-style cases use two sizes of terminal blocks.
The terminal block used for current sensing connections uses #8-32 screws with lock washers. The lock
washer is an integral part of the current-sensing wiring system and must not be removed. Without the lock
washer, the terminal screw may bottom out and prevent a tight fit against the lug. The torque applied to
the terminal screws should not exceed 15 inch-pounds (1.69 N•m). Each terminal block screw
accommodates a lug no wider than 0.344 inches (8.6 millimeters).
All other terminal blocks use #6-32 screws. The torque applied to these screws should not exceed 12
inch-pounds (1.35 N•m). Each terminal block screw accommodates a lug no wider than 0.320 inches (8.1
millimeters).
