It features a reinforced zinc die-cast housing for durability, and its offset pins are designed to make the ground connection first, which prevents damaging electrical arcing when plugging in. Over time, the terminal ends can corrode or the housing can crack due to vibration and weather, requiring replacement to maintain a reliable high-amperage connection. This 4-gauge version is rated for 100 amps continuous, making it suitable for most demanding lift gate and trailer battery charging setups.
