Terminal Blocks
There are two sizes of terminal blocks used on the “X” case design, the current circuit block and the input-
output blocks. The current circuit terminal block is the larger of the two types and uses 8/32 inch Phillips
head screws with lock washers. The input-output block is the smaller of the two types and uses 6/32 inch
slot Phillips head screws with no washer.
As stated, the current circuit terminal block on the “X” case uses 8/32 Phillips head screws with lock
washers. The lock washer is an integral part of the current circuit wiring system and should not be
removed. Without the lock washer, the 8/32 screw may bottom out preventing a tight fit against the lug
(screw feels tight but lug may move under the screw head).
The maximum wire lug width accommodated by the current circuit terminal block on the “X” case is 0.344
inches (8.6 mm). The maximum wire lug width accommodated by the input-output block on the case is
0.320 inches (8.1 mm).
NOTE
Except as noted, relay connections should be made with a minimum wire size of
#14 AWG.
