PowerPact J frame lug kits AL175JD and AL250JD

Both lug kits, AL175JD and AL250JD, include 3 lugs each. The lugs actually use the same lug body, but have different length wire binding screws to accomodate different sizes of wire.
-The lugs in the AL175JD have a longer wire binding screw to allow use of a smaller wire range of #4-4/0 Al/Cu. This longer wire binding screw has a BLUE TOP SURFACE.
-The lugs in the AL250JD have a shorter wire binding screw to allow use of a larger wire range of #3/0-350 Al/Cu. The shorter wire binding screw does NOT have a blue top surface.
In situations in which an AL250JD is required to be used with smaller wires, the longer blue-top wire binding screws can be ordered separately using the following part numbers.
S1A59551 (3 longer blue-top wire binding screws)
S1A59552 (6 longer blue-top wire binding screws)

The following video discusses the differences between the lug kits, highlighting the size difference between each type of binding screw:
