FAQs
Q1: Why is this lug suitable for high-amperage applications?
This lug is designed for 1/0 AWG conductors, capable of handling significantly higher current loads than smaller AWG sizes. The extra-long 1.5-inch barrel maximizes the electrical and mechanical contact area, ensuring efficient heat dissipation and conductivity under load.
Q2: How do I correctly prepare the wire for this long-barrel lug?
The wire must be stripped to precisely 1-9/16 inches (39.7 mm). The inspection window allows you to verify that the 1/0 AWG conductor has reached the stop inside the barrel, ensuring a full and secure termination before crimping.
Q3: Which dies should be used for crimping this specific lug?
For reliable and certified installation, use the corresponding die indexes: Panduit Die P42, Burndy Die 12, or T&B Die 42. Using the correct pink color code ensures proper compression.
Q4: What are the bolt requirements for mounting this lug?
This lug features two bolt holes with a diameter of 3/8 inch (9.5 mm), spaced 1 inch (25.4 mm) apart. This configuration is a common standard, allowing for robust mounting to bus bars or equipment terminals using 3/8-inch bolts.
